To roll back to the June 24, 2020, release and fix the Microsoft Outlook crashes, please follow these steps:
- Open a command prompt by clicking on the Start Menu and typing CMD. When the 'Command Prompt' result appears, click on it.
- In the command prompt type cd "\Program Files\Common Files\microsoft shared\ClickToRun" and press enter.
- You will now be in the ClickToRun folder. Type officec2rclient.exe /update user updatetoversion=16.0.12827.20470 and press enter.
Some Outlook users are reporting that the above steps do not work for them, but were able to use the
officec2rclient.exe /update user updatetoversion=16.0.12527.20880 command instead to resolve the issue.
