Hi All,
FIXED!!! in my case it was a classical error - in our Azure AD we had created a user with polich characters like Michał, after renaming the user to Michal and readded the Laptop via Intune Outlook did not crash any more.
So bleep always be very careful with using special characters...

Same issue here. Same setup as well.
Not been able to solve this one.

Microsoft seems to acknowledge the issue, https://support.microsoft.com/en-us/topic/outlook-closes-shortly-after-it-is-opened-2d32d880-70a0-4ee0-b1e9-9e920721abdd, but this registry fix does not make any difference.
