Email Requests- OAuth 2.0 "OAuth token not defined for connection. OAuth Authorisation required."

[Aaron Vo]

Our Jira's email requests using OAuth 2.0 used to work, but now it's not parsing emails.

We tried recreating the OAuth integration, and the test from there is successful, but setting up email requests returns the error "OAuth token not defined for connection. OAuth Authorisation required."

Any ideas what the fix may be?

After about 3 days, it eventually started working again. Related post below.

We are experiencing the same issue. It works for one of our service desk email request mail boxes but the other one gives us the error you are getting.

"OAuth token not defined for connection. OAuth Authorisation required."

The test connection works fine and all the scopes are set up correctly.

Maybe I need to wait a few days like you said for it to start working.

Did waiting help?  I am experiencing this same issue now.

The fix was making sure that the account that is authenticating the oauth has SendAs and Full access for the mailbox.

The mailbox we configured for the service desk email request is linked mailbox, there is no option to grant send as and full access. Any idea?
