Microsoft Outlook for Windows began crashing at startup for people around the world today. Reports of the issue began to surface late this morning, and it looks as if it's caused by a recent update. The company says it is looking further into the problem.
We're investigating whether a recently deployed update could be the source of this issue. As a workaround, users can utilize Outlook on the web or their mobile clients. Additional details can be found in the admin center under EX218604 and OL218603.We're investigating whether a recently deployed update could be the source of this issue.

If you're affected by the problem, you'll see Outlook crash immediately upon startup while throwing up the error code 0xc0000005. In an update to the Microsoft 365 Admin Center, Microsoft says it has traced the likely cause of the crashes to "recently deployed updates." Microsoft says it is looking at all recent service updates to determine the underlying cause before attempting a fix.
For now, Microsoft recommends using the Outlook mobile or web apps in lieu of the Windows app. However, as detailed by Bleeping Computer, there are a couple of workarounds you can try.
The first method incolces rolling Outlook back to the June 24 release. It involves entering strings into command prompt.
- Type CMD in the start menu and open "Command Prompt" by clicking on it.
- Type cd "\Program Files\Common Files\microsoft shared\ClickToRun" into command prompt and press enter.
- Type officec2rclient.exe /update user updatetoversion=16.0.12827.20470 and press enter.
- Follow the on-screen installer to download Microsoft Office and roll back to the June 24 build.
If the above steps don't work for you, or you want to use a simpler method to get Outlook working again, you can open the app in safe mode. You do this by holding the Ctrl key while launching Outlook. Windows will ask you if you want to start Outlook in safe mode. Click "yes" to continue.
Note that all add-ins will be disabled when running Outlook in safe mode.
We'll update this post with more information as it becomes available. In the meantime, you can use one of the above methods or open the Outlook mobile and web apps to access your email.
