Outlook Crashes when O365 emails are sent to or replied from365 groups?

Brass Contributor

We have discovered an issue when O365 emails are sent to or replied from 365 groups – Outlook crashes. 

Two different environments (unrelated entities) with the same issue. 

The issue has been occurring for quite some time (many months).  Each troubleshooting team (different groups of folks) has tried everything under the sink to resolve it.

 

 

The environments are:

  • Entity A:
    • RDS (2019 latest patches)
    • Office 365 (latest version) x32 and x64
  • Entity B:
    • Windows 10 devices (latest patches).
    • Office 365 (latest version) x32 and x64

It only happens when a user is working with O365 emails sent to 365 groups and replying to them. Happens on different types of equipment ie surface, normal laptops, etc. Tried many different versions of Office (32 bit and 64). Office in safe mode and no addons does not change anything. New profiles (windows and Outlook), new computers, etc you name it.
