PS: Salesforce is also suffering a widespread outage at the moment, which has even taken out its status page. Microsoft did not respond with more information at time of writing.

to roll back to April's working version (specifically, version 2103, build 13901.20462) but unless the situation is desperate it's perhaps better to wait for the fix and restarting. If you prefer not to disable the reading pane settings as described, you can still mark a message as unread if Outlook treats it as though you have read it. "C:\Program Files\Common Files\microsoft shared\ClickToRun\OfficeC2RClient.exe" /update user updatetoversion=1.20462 Some users report fixing the issue by running. It's no coincidence that Outlook has broken down on Patch Tuesday, when Microsoft and others emit security fixes and other software patches: an automatically installed update issued by the tech giant â specifically Outlook version 2104 ( build 13929.20372) â has seemingly screwed up the desktop client.
