AADSTS50020: User account 'hansdeweerd@hotmail.nl' from identity provider 'live.com' does not exist in tenant 'Synology' and cannot access the application 'af08ce07-1df9-4a39-b6e6-092ac934eb21'(Synology Active Backup for Office 365) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account. When trying to login to micosoft accoun I used for my synology account, I get his error what does it mean?
