Mailbox Not Enabled for RESTAPI

Hello, i have been looking for a solution to this problem but cant seem to figure this out. 

 

My app is using O365, Sharepoint and OneDrive Connection. It used to have an Outlook connection but I removed that because of this error which still didnt fix the issue..

 

The application works fine even with the error about 25% of the users are recieving this error? Any idea of how to resolve this or hide it?
