Suddenly and without warning, Thunderbird is no longer able to get messages. It just says DONE. Trying to get messages even from the menu bar does nothing. It doesn't prompt me for anything. Composing and sending work fine! I know it's an old OS Win7, but my other Win7 machines work fine. I'm afraid to do an uninstall and reinstall and lose very important messages. Can someone please help? Thanks so much! Jack116.0

Hello,

I am having a problem with Thunderbird on Windows when connecting my Gmail/Google Workspace account through IMAP.

The Google account authentication completes successfully and Thunderbird appears to connect to the account, but no email messages are displayed in the Inbox.

Here is what I have checked so far:

I am using Thunderbird on Windows. The email account is a Gmail/Google Workspace account. The account has been added to Thunderbird successfully. I signed in through Google's normal authentication/OAuth process. The account shows as connected in Thunderbird. IMAP is enabled and working on the Gmail side. Gmail webmail works normally and all my emails are visible there. Thunderbird displays the account and its folders. However, the Inbox contains no messages at all. I have checked the Subscribe section, but it does not show additional folders that I can subscribe to. I have already removed and re-added the account. I have also completely uninstalled and reinstalled Thunderbird and signed in again. The same problem remains after the fresh installation. The problem is therefore not simply that the account cannot authenticate; Thunderbird appears to connect, but it is not downloading/displaying the messages.

I would like to understand what could be preventing Thunderbird from synchronizing the Gmail IMAP mailbox.

Could this be related to:

Thunderbird's IMAP synchronization/cache, the Gmail IMAP folder/root settings, the Thunderbird profile, an IMAP subscription issue, OAuth2 authentication, Gmail's IMAP labels/folder mapping, or a corrupted Thunderbird preference/profile setting?

I would appreciate detailed troubleshooting steps to determine why Thunderbird can connect to the Gmail account but does not populate the Inbox with messages.

I can provide screenshots of the Account Settings, Server Settings, Synchronization & Storage, Gmail IMAP settings, or Thunderbird error/connection logs if required.

Thank you.

When I try to send a email from my secondary account I get the following error: A unique identity matching the from address was not found. Message will be sent using the current From field and settings Identity. In other words my main account sends a message to my secondary account. When I try to use secondary account I get the error message. The secondary account does not work now.

Thunderbird is downloading new messages but failing to display them.

Other functionality remains active, ie I can see and open messages, delete all the contents of folders, compose and send messages, but when the software downloads new messages they simply do not display and cannot be accessed.

Not sure if it's relevant, but the message INBOX count appears to be stuck at the number 59, although more messages than that have been downloaded.

Bizarrely this is the message displayed whenever I now open the Thunderbird application (it was there when the problem first appeared and returns everytime). Out of desperation I even made a donation in the hope it would release the messages!

Thank you in advance, Steve Davidson

For a few weeks now we have been unable to send emails through tbaytel server via Thunderbird. We get SMTP error. This happened after recent upgrades to Mozilla. Any idea when a fix will be out?
