A Microsoft Outlook update released today for the desktop client introduced bugs that prevent users from creating or viewing mail.
In an incident status message in the Microsoft 365 Admin Center titled 'EX255650: Issue affecting viewing email content in Outlook', Microsoft states that they have identified the root cause of the issue and released a fix.
More info: Impact is specific to the Outlook client and users with access to other protocols, such as Outlook on the web or the Outlook mobile app, can view message content in those platforms as a potential workaround while our fix is applied.
If you are experiencing this issue in Microsoft Outlook, users have reported that you can fix the bug by rolling back to a previous Microsoft Outlook version.
Microsoft Outlook will now be rolled back to the previous version, and you should be able to start Microsoft Outlook again.
If you do not want to roll back to a previous version of Microsoft Office or cannot find the ClickToRun folder, you can launch Microsoft Outlook in Safe Mode to fix the bugs until an update is released.
