Hey, i have a problem with one user in my organization,
i get error CAA50021 when he tried to connect to his mail -
i tried to do everything in this arcticle
https://enterinit.com/something-went-wrong-error-caa50021/amp/
and i checked in Azure AD admin center->Devices->Devices settings, and check if “Users may register their devices with Azure AD” setting is enabled
any ideas?
Hi @Noam Atias
What application did this error occur on?
Based on my research, this error seems to be related to Azure AD join and registration service.
You could contact your admin to check if Mobile DeviceManagement for Office 365 or Microsoft Intune services is enabled.
Any updates, you may post back.
Hi @Noam Atias

Hello, the solution that I found and that has always worked for me is the following:
-go to settings
-accounts
-get access to work or school
-select the user account and click on "disconnect"
-then restart the PC and log in again to the office application that has the error
