Using Outlook for Android for personal email and calendar management
The way we "fixed" this where I work: (not really a fix, it's a workaround)
- Remove Work profile
&& Remove Company Portal
- Remove all phone identifiers from Intune.
- Full Factory reset
After confirmation of completing factory reset (y'know, because users):
- Add device to allowed list in Intune
- Install Company Portal
- Log in with work account
Fixed it in about 90% of cases, some needed to do this twice or it didnt work at all...
Only had succes without factory reset once or twice on a test device... not on something being used daily.
And I've only seen it happen om Samsung devices.
