  • Please add a guide how to uninstall Outlook2016 from Office365 because any email with appointment request ends up in OL instead of the mail app. There is also no option to change the "Standard App" settings to the default calendar app.
  • Unfortunately, I'm pretty sure with Office 365 you can't uninstall individual Office apps. You should still be able to change the defaults in Windows if you go to control panel > programs > default programs > set your default programs > Mail (or calendar, whichever one you want to change) > set this program as default > OK.
  • I tried that, the settings for Outlook2016 are not unselectable. E.g. ICS files always go to OL2016...
  • I am also pretty sure that the latest Office365 installer does not let you select which applications to install nor let select individual apps to uninstall. Which is extremely frustrating.
  • Is it possible to sync Facebook calendar events with windows 10 desktop calendar?
  • Yes, you need to go to outlook.com and then select "New", "Internet calender". Then paste the calendar links (webcal) you can find in Facebook on the events page (at the right below all events you will see a box explaining how to get internet links to the calenders). There are events and birthday links. The events work, the birthday link has not been working for two or so months.
  • How to add an event from .ics file?
  • I could only get that to work with office mail client desktop. No go on phone, also no support for attachments in meeting invites.
  • Use the import function in outlook.com (select Calendar and then import). This will sync to your PCs calendar.
  • What I'm interested in: Sync my Win10 calendar with my calendar on my Ipad. Sync my Win10 calendar with my Samsung phone (S-calendar)
  • I'd like my calendar on my phone to not tell me when US holidays are and instead tell me about Australian holidays, but I guess that's too much to ask.
  • I've been having trouble syncing a calendar but to win10m, in mobile I don't have the option to turn on and then off the calendar switch. Any idea on how to fix this?
  • will 10586.456 will be releasing to production build ? or MS is going to release direct Anniversary update on Aug 2 for mobiles ?
  • Still such a lame app on the phone! Still cannot select or deselect calendars from various accounts! Argh! MS come on!
  • Windows 10 Mail is no longer syncing my mail automatically. Please help.
  • What makes me sad is that even if you choose the city, it will not adjust the timezone! =( If you have meetings at many countries (with Skype, in my case), would be much nicer!
