      Hello

      We have an issue with configuration the PostMaster mail account with Exchange Online.
      I configured the application in Azure Active Directory with a redirectURL like https://xxxxx/otobo/index.pl?Action=AdminMailAccount
      I configured the oauth2 system parameters in System Configuration -> Core -> Email -> OAuth2 with the secretID, domaine name, and applicationID, with the Scope parameter configuration with: offline_access https://outlook.office.com/IMAP.AccessAsUser.All

      but each time I save new postmaster email user credential prompt pops up but after fill in password nothing happens and I’m redirected to the redirect URL with error log in the system logs:

      Could not request access token
      Got: ‚401 Unauthorized‘!
      Can’t perform POST on https://login.microsoftonline.com/xxxxxxxMyTenantIdxxxxxxx/oauth2/v2.0/token: 401 Unauthorized

      Thanks for your help.

      thanks for reply, but we think that the problem is with server configuration on otobo side, as we tested on different server with the same Azure AD settings and it’s working fine :/
