Microsoft’s Outlook is crashing for people worldwide, River Net has the fix.
Microsoft’s Outlook email app for Windows is crashing at launch for a large number of users around the world. Office 365 business users are reporting that Outlook launches and then crashes immediately, seemingly after a recent update. “We’re investigating whether a recently deployed update could be the source of this issue,” explains Microsoft in a Twitter status update. “As a workaround, users can utilize Outlook on the web or their mobile clients.”
These crashes started occurring over the last hour, and reports are flooding in from users all over the world.
Users who examined their Application event logs will see an error log stating that the OUTLOOK.EXE program has crashed with an exception code 0xc0000005.
In an incident status message in the Microsoft 365 Admin Center titled ‘EX218604: Users experiencing Outlook connection issues and crashes’, Microsoft suggests users use web and mobile clients until the issue is resolved.
Microsoft Outlook users have had success rolling back to a previous version of Microsoft Outlook to resolve this issue, which is explained in the next section.
BleepingComputer has contacted Microsoft for more information but has not heard back.
River Net suggests to try the following:
Click the Start Button and type CMD and hit enter.
A Command Prompt should show up, RIGHT click it and “Run As Administrator”
Copy and paste the following text into the black command prompt window:
cd "\Program Files\Common Files\microsoft shared\ClickToRun"
officec2rclient.exe /update user updatetoversion=16.0.12827.20470
Affected users should be able to log into Outlook on the web until the issues are resolved. IT admins over on Reddit are also testing a variety of workarounds to roll back the update that appears to have caused the crashes today.
We’ve reached out to Microsoft to comment further on the Outlook crashing problems and we’ll update you accordingly.
