We have approximately 100 computers and outlook started crashing for some people I would say after Windows 21H2 update or maybe sometime around that update. We tried repairing office from control panel, renaming the .pst file to .old so it would get re-downloaded and also creating a new office profile and nothing helped. I also tried with another outlook profile but the issue persist. When outlook is use in safe mode that does not happen but it could be a coincidence. I also tried download "SARA" from Microsoft and it didn't find any issues.
Windows and BIOS are updated to the latest versions and so is office, basically all updates are installed.
