Hi @ARajagopal2 ,

Can you maybe share some additional details (potentially examples or screenshots) of how you actually want to integrate Jira with your mailbox? Also, are we talking about Jira or JSM, and which environment are we looking at (on-prem or cloud)? 👀

Generally, you can try to re-authorize the mail server (as stated in the previous answer) and/or it might depend on whether we're looking at a distribution list (DL) rather than a direct mailbox.

Also, if you're on an enterprise plan in the cloud, I'd maybe suggest reaching out to your Atlassian or IT department, who can probably help you out with this 🤔

Cheers,
Tobi

This sounds like an OAuth authentication issue rather than a problem with the mail queue itself. I’d first re-check the mailbox OAuth connection and make sure the authorization hasn’t expired or been revoked.

Also verify that the configured mailbox, OAuth credentials, and required permissions are still valid. If the connection looks correct, try re-authorizing the mailbox and then send a test email to confirm whether ticket creation and automation start working again.

If it still fails with “Failed to retrieve OAuth token,” checking the application/server logs for the exact authentication error would be the next step.
