Oauth2 SMTP error

jnyunt

Hi Guys,
I have osTicket (v1.17) on Centos 8 Stream. I was able to setup Oauth2 for imap and able to fetch email from mailbox. However when setting up SMTP , Oauth2 was successfully configured but unable to save the email config itself and giving me 5.7.3 Authentication unsuccessful error. I was following the guide https://docs.osticket.com/en/latest/OAuth2/Microsoft%20Authorization%20Guide.html . smtp.send is allowed in API permission. Please see the screenshot

If you have OAuth2 setup for IMAP on the same email then set SMTP to Same as remote mailbox and retry. If you still get the same error then you’ll need to contact MS for further support.

Cheers.

sorry ntozier for taking too long to reply. this has worked for some and not other, I still get '5.7.3 Authentication unsuccessful' . I haven't followed up with MS yet.

Everyone that has ran into this error has had to delete the email completely from O365, recreate it, re-add it to osTicket, and re-configure the email/OAuth2 settings.

Microsoft has a real issue on their hands yet they just throw the blame around and provide no real solution, ever. I suspect it has something to do with old accounts that were migrated/messed with after the Legacy cutoff in October.

Cheers.
