O365 group not populating in Outlook

Norbert de Graaf 6

I have 2 users who are members of an O365 group and on 10 Feb the mail folder for this group in their Outlook stopped populating. Bottom of the screen shows "This folder has not been updated" OWA shows them there. I made myself member and mine is working fine. Outlook is up to date. I have enabled "Turn on Modern Authentication" in the Admin portal. I have an open support ticket with MS but response is slow. Last resort is to remove and recreate profile for user but thats disruptive for this high profile user. 80gb mailbox size. so not an option right now. Any ideas or suggestions welcome, thank you.

It is recommended that the Outlook profile size be less than 50G, otherwise it will cause various problems.

So, I would suggest you create a new configure a profile for this mailbox for test (Do not need to remove old profile). We could create multiple profiles for one Outlook client. If you could see emails from this new profile, it means this phenomenon caused by the size of profile.
