Fix for the botched Calendar app on Windows Phone 8.1 is now live in the Store

Earlier this afternoon we harangued Microsoft about the recent Calendar app update for Windows Phone 8.1 that occurred on Monday, June 30. The update virtually broke the app for thousands of users by crashing whenever one adds a new appointment. Soon after our article, the app was unpublished from the Store preventing users who rely on auto-app updates from suffering the same fate.

Tonight, Microsoft's Joe Belfiore took to Twitter to address the situation, noting that a fix would be available very soon.

"WP8.1 Calendar fix is ready and getting posted to the store. Will take a bit of time to show up everywhere. Sorry for the inconvenience!" – Joe Belfiore, Microsoft

Apologies aside we knew Microsoft would quickly address the bungled update though it still raises questions about how such an obvious bug made it through certification. People may brush this off by claiming Windows Phone 8.1 is currently in beta (it is not) or we knew what we were getting into when we signed up for Preview for Developers, but the truth is official 8.1 devices have been on the market for weeks e.g. the Lumia 630. For the sake of the platform's success, such incidents simply cannot happen if Microsoft expects to make any inroads in the competitive mobile space. They need to execute flawlessly.

For now, if you're on Windows Phone 8.1, you can head to the Store to get version 1.0.14127.247 of Calendar.

Update - For the record, this is not a new version, but rather the old one prior to the June 30 update. While it's a 'quick fix' for the add appointment bug, it also brings back a region specific bug affecting those in Russia (opens in new tab). We surmise that Microsoft will attempt once again to update Calendar in the coming days with bug fixes, making it a true update. Thanks, @Alovchin91, for the heads up.

  • Download Calendar for Windows Phone 8.1 Note: Since this update is so new, you may not see it in your region right away. If that is the case, please try again later once the update has propagated to all of Microsoft's Store servers.

  • Yes. It works again.
  • It was stopped on my phone - +820
  • Why can't Microsoft put an Every other Feature in the Occurs option? Every other Friday, Every other Saturday, every other Monday. I have games, trainings, paydays, weekend worked, all kinds of crap that occurs Every Other Week and all these years Microsoft still can't put in that lil feature. And why the hell can't it go Landscape!!!??? WTF MS
  • thats a really great idea wonder why people aint talking bout this.....why come in handy with school time tables and such  
  • My live tile will not update. Anyone else?
  • It's working ok for me.
  • Try rebooting your phone. I've had that work in the past.
  • Still having this problem in 2016 and by now it is clear no update is ever coming. When that happens, the notifications don't work either, so I missed some appointments I had in my calendar. Yay Microsoft!
  • The punchline is don't be lazy and use auto updates.  Look before you leap - read the version notes and apply a sanity check before putting stuff on your phone and whining about it here later.  I say this with love
  • I knew they weren't sitting doing nothing... I hope MS learned a lesson and wont update again without testing
  • Microsoft should be in shame of themselves for releasing an app without testing it.
  • ...yeah, its a real shame!  Broken apps would never happen with Apple or Android...  :-D
  • Are you sure?
  • Frankly, I have not faced any broken calendar, google play, gmail, etc on Android before.
  • ...you must be either extremly lucky, or kitting or have a short memory.  Just check the various communities about Apple or Android app glitches. You will have a lot to read......  :-)  
  • Return to Android
  • When our how often would you get an update on those platforms?
  • Really!?  Then perhaps you can explain these: http://appadvice.com/appnn/2014/03/glitch-removes-apples-stock-apps-from-ios-7-1 http://www.cnn.com/2012/07/06/tech/mobile/apple-glitch-fixed/index.html https://groups.google.com/forum/#!topic/google-calendar-help-dataapi/Z_RkJD7BZyc  
  • LOL!!!!! Core Android features force closing (including the home screen) was one thing that made my next phone a Windows Phone.
  • +1520
  • We hold Microsoft to a higher standard.
  • everytime apple updates it's OS it always gets screwed up . go to there forums and see for yourself. thats why i never update my ipad or ipod. there both the same as when i bought them.
  • I can't Believe you people are Unglued. I tried to add and event and it didn't work. Then I tried a few other time and Just moved on. I knew in 1 to 2 day my patch would be in. When life deals you lemons make lemonaide or move to apple. Just shut up about it, quit your crying.  
  • Why, was apple ever ashamed of that map situation they put out?
  • Microsoft just wouldn't be Microsoft without fixing unbroken things by breaking them just to have to find a way to repair that unbroken thing they broke.
  • Had to read your comment twice, but going by what MS's been doing lately to WP apps, I've to agree with you.
  • Read you comment twice, and I agree with you!
  • Is probably an intern test. They have 24 hours to fix a live problem with the least number of consumer complaints.
  • So many smart guys here make me sick.
  • Yeah, they do a fair amount of whining when mistakes are made. Just listen to 'em scolding MS like it wet the bed. lol.
  • Instead of upgrading app MSFT sometimes seems to downgrade them
  • Summer interns need to start somewhere.. WP team!
  • I think someone wanted a bit of overtime to pay for their upcoming holiday, maybe :D
  • Lol, -calendar update
  • Yep it seems 90% of WP devs are summer interns!
  • Yeah. Obviously, they were not doing these intentionally. But making WP native apps upgradable without having to update the whole system was for the betterment, at least that was what they wanted. First time experiments often fail but the least they could do was to test it without releasing. At least that's what we could expect from MS but now we've to rethink while updating... Or that they'll rethink.
  • Great news ! I knew this would get fixed within 24 hrs and indeed it did. :)
  • I doubt anyone truly felt that it would not have.
  • Maybe it was all a social experiment
  • :) see what you did there, I did.
  • +520
  • Got it
  • Working fine again! +920
  • Just got it. As for this entire business...I wonder if the apps are even going through testing anymore. This clear blunder left me with more doubts about the quality control on the store than anything else...
  • I don't think the qc on store ever check apps by MSFT. The only way left for us is to turn off the automatic updates
  • This is why I never update automatically.
  • Well they clearly should. Though even generally, the quality control had been dropped in the store. Fortunately I don't have automatic updates enabled. I like to see what gets updated and when manually.
  • Well, those things sometimes happen. Maybe someone uploaded the wrong release or they thought their update was so minor nothing could go wrong. As long as it does not happen all the time and gets fixed in time I don't have that much problems with it.
  • Did you ever stop to think that maybe they DID test it and it worked perfectly on the devices "in-house," but those devices didn't have something on them that the rest of the world does?  Or perhaps someone messed up and didn't load the correct version onto the Store servers?  Many things can happen when upgrading apps, especially at the pace Microsoft has been.  God knows Apple and Google aren't immune to these kinds of glitches.  Bing it if you don't believe me (see what I did there - Goog what?)  Instead of COMPLAINING all the time, appreciate that Microsoft is working extremely hard to create an OS to rival the competition.  Look at the progress they have made in just the past year alone.  Microsoft IS listening to us and they AREworking as hard as possible to provide us with features we want like Cortana, Action Center, etc.  The fact that they fixed this issue in one day proves it.   Are there still issues?  Of course, like Xbox Music (I really want them to make creating and editing playlists easier - similar to Android where you just create a playlist, name it and then select the songs you want in it and click save.  And I would LOVE it if we could have interactive live tile for Xbox to pause/play/ffwd/rev songs from the live tile.)  But I digress.  We have to support Microsoft's attempts and accept some glitches and setbacks in order to reach that ultimate goal of having the BEST OS on ALL devices.  I sincerely believe that THRESHOLD OS (Windows 9 / WP9?) will be the thing to blow Apple and Android out of the water!  Let's hope I'm correct.
  • +1
  • Thank you for being a voice of sanity here NOLATechy
  • I wish they bring the weather within the calendar back. It's a small feature but yet useful...
  • Just got the update, I got weather.
  • Still get weather in week view... Was it in any other view?
  • Weather isn't working for me either, hmm?
  • Make sure location is turned ON or you wont get weather in Calendar.
  • I get weather, location has to be turned on.
  • No more weather for me either, It was working fine before latest update. And yes, all location services are turned on. Lumia 925.
  • Fixed. Had to go in to calendar settings and turn off location settings, back out and then go back in and set location settings back on.
  • Nice, this fixed it.
  • "Microsoft Account Service is unavailable"
    To many downloads I guess?
  • GREAT. They broke this again: http://social.msdn.microsoft.com/Forums/en-US/a8ee579b-d6c0-48be-a1b0-1d... Are they crazy?
  • HAHAHAHAHAHAHAHA I LOVE MICROSOFT
  • I wonder how they are going to start selling Lumia 930 in Russia next week with this bug. A usual user will just return the phone.
  • I'm not sure you're very familiar with the "usual user". How many people have choked down the crap android was pushing at them without returning their phone?    
  • It was on 18 may... Not now... The app fully functional now
  • No, it's not. They fixed it yesterday, but broke new/edit appointment. Now, they fixed the latter bug, but broke this again. Seems like they just pressed "Undo".
  • I too guess its just "undo" with change in version number
  • You should know, MS can't fix one bug without causing 5 more ;)
  • Yeah, seems so lately :/
  • And please note that I really posted this thread on May 18, but they fixed it only yesterday! And moreover, today we don't have a fix for this yet again.
  • I wonder if they'll have to update OS to fix this issue.
  • Just tried (Lumia 720), I didn't notice that when using 24h date format.
  • Try switching the time zone in phone settings to GMT+4 Moscow. It's not because of 24h time format, it's because of time zone changes in 2011 in Russia.
  • Thanks for the link!, so glad I don't have auto updates enabled. I don't think it needs an o/s fux but more stringent and robust qc of their own apps. As it looks like MS will never kick the habit of breaking things that are not broken lol.
  • Not showing events on the tile.
  • I too am having issues with the live tile.
  • Not showing the events in the live tile
  • Seems faster
  • When rapid release gets too puffed up.
    This incident, like the recent Outlook outage, just can't happen. We are paying customers guys, not guinea pigs.
  • I don't understand the uproar, 8.1 is a dev release, not a mass release. Use with caution.
  • It's already out on new devices like 630.
  • No, it is not.
  • It's the final release
  • The only "final release" is for software that is end-of-life (EOL), meaning no further development and expiring support. The correct term is Release to Manufacturer (RTM). I disagree with Daniel.  RTM does not guarantee full functionalty.  Full functionality is determined by manufacturer, for computers this would be HP, Lenovo, etc.  Mobile phones are unique in that this is two step:  manufacturer (Nokia, HTC, Samsung, etc.) and carrier (USA only apparently. The easiest analogy:  buy any laptop pc.  For example purposes, install clean Windows 7.  I guarantee no full functionality from that laptop until you download drivers from manufacturer website/CD.  That is where Windows Phone Developer Preview is at.  The app problem is a different issue.  Clearly, it is a QA issue whether incompetence or incapability. On the bright side, interns will cycle out in a month and the real devs return from vacation.  Hang in there folks!
  • Thanks for such a nice explanation
  • WP8.1 on the Lumia 635 isn't RTM or preview, it's the final release save for what's coming in Cyan.
  • Again, there is no such thing as a final release unless the software is dead, i.e. Windows XP.
  • Glad someone else understands this too. Was getting tired of explaining it myself. :)
  • Well said! And then there's also the effect of a build for "RTM" being different and may behave differently from a "preview" build. Past BETA releases of many other products (not just from MS) behave differently from RTM'd ones when 99% of the code was unchanged. Some things may be enabled or disabled when it's switched from a debug build to 'general release' build as debugging and feedback features are turned off or others turned on which can cause behavior differences. I think of all the times I've run into issues where enabling debugging or using checked builds appeared to 'resolve' issues in some cases, and ressurected 'fixed' bugs in others, yet the code itself remained the same. But this was not the core anyway. It was an app provided with the core and never should have never made it out into the wild. I think back to my days of testing, and back then, every button, checkbox, slider, network connection process, interop with other apps, etc. all had to be tested and was verified by at least 4 other testers (5 total) and you had to sign-off on each item individually. I wonder why that did not happen here. Did testers simply assume it worked and signed off without actual verification? Was it simply seeing if it installed? Ineptness/incompetence definitely seems to be the case.        
  • We have a joke here in the US, sounds like an indian job [indians are known for taking shortcuts and releasing partially-baked stuff]. Maybe the indian in charge just gave it the A-OK and published it to store. hahaha
  • Since Windows Phone 8.1 isn't a final release, and Microsoft is shipping Lumias with these bugs on them to consumers, we should assume that Microsoft won't accept payment for those devices until after the software is fully functional and usable, right? When do the refund cheques to Lumia 630, 635 and 930 owners who thought they were purchasing a usable, ready-for-prime-time device with working calendars get issued?
  • Yes, Got it :)
  • I know I'm on a preview version, and I know MS will resolve these things quickly, so I wasn't worried at all! :D
  • No, it is RTM
  • True, but mine would still be preview. I'm not a manufacturer, lol
  • And it is quicker to launch then it was before the updates!
  • Great that they fixed it quickly. But they still have the AM/PM bug (does not respect formatting setting of 12h/24h). Sigh.
  • Glad I'm not the only one who is annoyed by this..
  • It doesn't use my date format either. Date format for my locale is YYYY-MM-DD but the date picker in Calendar uses MM-DD-YYYY. It was fine in WP7/7.5/8. 7/7.5 was even better in that regard as you could customize your date formats.
  • How hard can it be to fix this... It's annoying.
  • +720 or may I say that I'm extremely agree with your sigh ;)
  • It happened because there is no qa, it should be more simple to roll back massive issues than spend a day coding a fix
  • Great, now fix Bing Weather
  • How can a weather forecast get more inaccurate? Bing weather.
  • +HTC 8S
  • WHY CANT THEY USE THE SAME URGENCY AND FX THIER BOTCHED MUSIC crAPP?
  • +920
  • +920000000000000
  • Oh Danny Boy, one glitch in such a complex world or coding is not the End of the world, just like Malware and Trojans aren't killing the Android momentum
  • The quality control should have atleast checked once before submitting the app but they didn't.. Laziness laziness everywhere
  • Its not a glitch that is difficult to replicate but a simple function as adding an appointment which caused the app to crash. This is a core app not some third party app one downloads from the store.
  • Yay! Downloaded fix and it's working
  • Happy to know that MS is actually listening to us :)
  • "The update virtually broke the app for thousands of users" Where are the Android wags posting they didn't know there were that many WP users?
  • Nahhh! I can't use my phone until now. Stocked on home screen becaise of this.1hr ago have already passed and no response yet. Soft reset doesn't work. Now I know what is the limitation of uni body. I'll definitely download this update, as soon as I turned on my phone.
    Lumia 720
  • I went to install app from the WP Central app and it said "View" Lo and behold, it had auto updated while I was eating lunch. Confirm it again works as advertised.   Now, where is my next update for "Music?" Overdue, lads.
  • Bad  form to release a busted update. Great form to fix it asap.
  • The update is live in Vietnam. Tested ...fixed!
  • I've never had an android or iPhone. All windows mobile and I waited until wp7 came out. Only thing that upsets me this late in the game is I want and will continue to support no matter what but common with the updates already. Official 8.1 is out, 630, and I do have preview on my 1020... But push the darn official out and move on to the next update, should get the one after that before Christmas also...
  • Wow that's the first time I've been really upset with Windows Phone in my three years of use. I depend on the calendar app, probably my third or fourth most used feature because I do shift work - never remember where I need to be! Glad the fix came quick, unhappy the issue existed in the first place. Onto some good news, now :)
  • Seems Working ..
  • Thanks in Lumia 920 now it's work very well
  • Music fix..please
  • What are they going to fuck up next, the phone dialer? Oops, but wait something HUGE is coming soon! Pffft. I'll get excited when you can do basic shit.
  • They didn't break the email app yet...
  • Nah, they'll break the calculator first.
  • Don't worry dialer and email app are next, rest everything is already fucked up... Just let that huge update come up
  • The update is available in Mexico and does not open the app, it says that i need to buy it. Lumia 625.
  • And then MSFT said let Richard buy the calendar app
  • Yes, only because we can't upload images from the app i can't show you the screenshot.
  • I just cant believe you, but still save a screenshot, use twitter and send it to WinPhoneSupport
  • And if possible send it to me as well on twitter @yoursRitesh
  • I send it to Joebelfiore account.
  • I have no problem with MS having a bug in an app here and there but when I pay for a music app and after 3 years its still subpar and basically garbage compared to Zune i get pissed.
  • We all hear you and on board. Until they fire who ever the ego maniac is in charge of Xbox Music and Video, that is not listening to us, that we just want Zune back rebranded, nothing is changing.
  • +920
  • live tile doesn't work.
  • solution: restart my phone and it work.
     
  • 'Calendar Update for Windows Phone 8.1: A cautionary tale.'
    By Daniel Rubino.
    (I'm making light of it with this post but in all seriousness, this is a great entry that Belfiore and his teams should pay attention to regarding Windows Phone.)
    ((But this is a VERY prompt response and I'm completely stoked about that. Good job.)) EDIT: Forgot quotes. And a bunch of other stuff...
  • Apps like calendar, music, video, file manager and folders they should be build in OS. We install so many different apps for doing so simple things. WP 8 were smoother in apps like music games calendar and so on. The OS is really good but I believe even with WP 9 it will still be incomplete. For me its a shame that I can't send a full size photo by build in mail app and need to install another app for this reason when I got a Lumia 1520. That's all for me right now.
  • Yehey! Cool fix.
  • But when I close the calendar app, it stays in back, I have to close it from multitask-screen.
