I have been using the Thunderbird email client on my Mac for a long time to access my corporate Gmail account.
(This is not a personal Gmail account, it is a corporate Gmail linked with Okta.)
In this corporate Gmail account, I do not have access to "App Password" settings or "Less Secure App Access" options.
Everything was working fine until 25th April 25. On that day, I updated my Okta password, which also affected my Gmail account because Gmail is connected through Okta.
Since then, my Thunderbird email client has stopped working.
It keeps asking me to allow Thunderbird to access Gmail, and even though I allowed it many times, the same pop-up keeps appearing.
To troubleshoot the issue, I have tried the following steps:
- Reset my Okta password again to rule out any password issues. (I am able to log in to Gmail successfully with the new password and I can configure the same Gmail account with the Mac Mail app without any issue.)
- Upgraded the Thunderbird client to version 137.0.2.
- Cleared saved passwords and cleared cookies. (Note: "Accept cookies from sites" is enabled under Web Content settings.)
- Deleted the account from Thunderbird and tried to re-add it.
After this, I started getting the error:
"Unable to log in at server. Probably wrong configuration, username, or password."
- While adding the account, I entered my name and email address, left the password field blank, unchecked "Remember Password", and filled in the configuration manually.
When I clicked on "Re-test", it detected the server settings correctly.
But when I clicked on "Done", I got the same error again.
- Created a completely new profile in Thunderbird and tried again, but still faced the same issue:
"Unable to log in at server. Probably wrong configuration, username, or password."
- Uninstalled Thunderbird completely and reinstalled it, but the issue still remains. (Please refer to the attached screenshot.)
- I tried the troubleshooting mode, which disables all the add-ons and themes, but the issue is still the same.
Any help would be appreciated.
I'm not sure if this is relevant, but Gmail has made some changes (see the link https://support.google.com/mail/answer/7126229?visit_id=638814378228955739-1844270273&hl=en&rd=1). This might be causing the issue, though it was working fine until I reset my password on April 25th.
