Hello,
since Saturday, 9th Sept. 2023, ca. 14:00 GMT my Thunderbirds are producing error messages.
I have added four different outlook.com email-accounts, each with IMAP+TLS+OAuth2 as incoming server and SMTP+STARTTLS+OAuth2 as outgoing server configuration. The error messages are only regarding these outlook.com-accounts. A gmail.com-account with the same settings is not affected.
I encounter constantly popups with the following error messages:
- "...user ist authenticated but not connected"
- "the server is offline"
- something like "authentification error while connecting to server outlook.office365.com"
Also the Page where i should enter the password to create the OAuth-Token keeps opening and closing before it could load completely.
The most astounding thing is, the synchroniziation seems to work nonetheless. It's just the messages that annoy me.
Here is an entry from the Thunderbird error-log:
"mailnews.oauth: Error response from the authorization server: invalid_grant; AADSTS50196: The server terminated an operation because it encountered a client request loop. Please contact your app vendor.
(...) https://login.microsoftonline.com/error?code=50196"
The problem occured more or less suddenly on 3 different PCs:
- Two Windows 10 Pro 22H2 machines with the Thunderbird versions 115.2.0 and 115.2.1
- A Fedora Linux machine where Thunderbird 115.2.0 is installed via Flatpak
What I already tried with no success:
- De- and reinstalling Thunderbird with deleting _all_ user Data
- Upgrading Thunderbird from 115.2.0 to 115.2.1
- Revoking the access for the Thunderbird-app in the Microsoft.com account OAuth-Settings and granting it again when creating a new token by logging in with Thunderbird
What my inquiry has delivered yet:
- Thunderbird seems to have problems to remember the OAuth-Tokens. When I look in the privacy settings at the saved passwords I can see that the passwort seems to change constantly. In contrast, the Google-gmail.com-account keeps the same passwort.
- It seems to be especially triggered by closing thunderbird and opening it again shortly afterwards, though it does happen without doing so too.
- The error messages pop up and the password-page opens mostly when I click on a folder (presumably because Thunderbird is trying to sync it then)
My accounts seem to be fine. I have no problems accessing them with OAuth2 via K-9 Mail on my Android 13 phone. I can also log in via the Web Interface.
Thank You for your Time!
