The latest release candidate for OSTicket 1.17RC3 includes support for the new oAuth2 authentication method for IMAP and SMTP.
We have trialled this with Google and Microsoft, and to no ones’ suprise the Microsoft one is presenting issues. We have it authorising with oAuth2 but IMAP then throws us out. I imagine this will be resolved by the time the final release is provided.
Google Workspace took us 10 minutes to configure and test with oAuth2. Microsoft … 3 days later, not working yet 😛
