Intune work profile outlook keeps asking for password

[junaid04]

I have an intune work profile installed in organizations personal cell phones. When using outlook people are facing an issue that outlook keeps on asking for password again and again after some time. Anyone who could tell me the reason and solution for this error

@junaid04  It sounds like there is an app protection policy assigned for Outlook assigned, requiring a PIN for access. This is set in the Access requirements section of the app protection policy.

@junaid04 Is there any particular phone model? Let me guess, some kind of Android?
