I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.

Hey all, I installed the current version of Tbird on a couple of machines for a friend, one machine worked fine for a month or so, then started giving the "unable to write the email to the mailbox, make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox" error. There is a ton of free space on his C: drive, hundreds of GB. Yesterday I installed Thunderbird to another of his PCs, also no 3rd party AV (both running Win 11), same exact error after downloading a handful of emails from a few weeks ago. To make things weirder he took his laptop (the machine that worked ok for a short time) to his office, where he has a different ISP and it downloaded all of his mail! What is going on here? I have seen plenty of threads about this error, I tried compacting, repairing the folder etc, nothing fixes the problem and Thunderbird sits there not syncing his mail. At the bottom of the window it shows that there are 200 or so emails to download, it looks like they are downloading for a bit, then it quits trying and gives the error. Is there a known cause of this seemingly common error? Are Thunderbird devs aware there's an issue that renders their software unuseable for some users? His mail account is with Brightspeed, an old centurytel.net account. Please share any tips you may have for overcoming this error, thanks!

I have been trying to add new email accounts to Thunderbird and they never complete the process (I have several that configured correctly prior to this error). I have tried both automated methods (With and without HUB) and the manual method of adding an account. Here is what is happening. When I add an account, I can watch Thunderbird login to the account on the status line. The login goes correctly, however the "Done" tab is always greyed out, the process never completes. I then try configure the account manually at the same screen and I get "the server is already in use" message. I believe that Thunderbird is not correctly closing the connection, leading to the "server is already in use" message, but I am not sure how to correct the issue.
