What terms did you try when SEARCHING for a solution: "HESK Office 365 SMTP ERROR: AUTH command failed: 451 4.7.0 Temporary server error" "HESK Not connecting with Office 365" "SMTP Error HESK Office 365" "Hesk error Error: Authentication failed: AUTH command failed office 365"
That got me to these help articles: https://www.hesk.com/knowledgebase/?article=93 and https://www.hesk.com/knowledgebase/inde ... rticle=111
I verified the OAuth Provider, it's working correctly and it's Verified.

I'm trying to set up an Email account for Ticket Verifications, everything went fine up until the point of testing the connection, where I get the following error message:
I tried restarting the http server, I undoing and redoing all the OAuth configuration all over again in Azure but no luck, still the same error. The email address is correctly spelled, there is no password since I'm using OAuth. 2FA is enabled, and I cannot change that setting, but that shouldn't affect anything since I'm using OAuth. SMTP Access is allowed for all accounts on the Domain.
I ran out of options and my knowledge on these kinds of problems is limited because It's my first time using Office 365 and Exchange online in a professional setting.
