Hello,

I am trying the oauth2 plugin to overcome the MS limitation planned for end of Sepember, but I am struck…

1. I registered an application in Azure
2. I setup a redirect URI to the local IP (since it’s not published) : https://172.22.20.226:8443/otobo/index.pl?Action=AdminMailAccount
3. I assigned the DELEGATED API permissions with ADMIN CONSENT
   1. email
      IMAP.AccessAsUser.All
      offline_access
      POP.AccessAsUser.All
      SMTP.Send
      User.Read
4. I created the SECRET
5. I modified the Povider inserting my tenant id

I am still getting errors…

Wed Aug 10 14:20:12 2022 (Europe/Rome) error OTOBO-CGI-11 Could not request access token
Wed Aug 10 14:20:12 2022 (Europe/Rome) error OTOBO-CGI-11 Got: ‚401 Unauthorized‘!
Wed Aug 10 14:20:12 2022 (Europe/Rome) error OTOBO-CGI-11 Can’t perform POST on https://login.microsoftonline.com/4d0aca28-2980-409e-8efa-7351d66d1be2/oauth2/v2.0/token: 401 Unauthorized

Any idea on how to debug this problems ?

Thanks,

Massimo
