Question Thunderbird: Unable to write the email to the mailbox - GMAIL account only

[Great White North]

I have been receiving the following message for 2 days. This comes up for my main Gmail account only, and I have about 8 other accounts, including 2 other Gmail accounts that rarely get emails. The other 2 emails can receive emails and get no error messages.

"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."

I have repaired the account and compacted it. I've also deleted half of the emails in the account, as well as form the sent and trash versions of the account.

I also rebooted the program several times, and later rebooted the computer.

The version is 102.11.2 32 bit

At times, one message from Zoom that was originally sent at 1:12PM on June 5 keeps appearing, that gives me the code to enter because Zoom didn't recognize my account. That email didn't come through originally, and has since come through hundreds of times, and only on my PC, not on my phone, which uses Blue Mail as the client primarily.

Does anyone have any suggestions?

Have you read and followed the instructions given here:

Thanks. Turns out it was set up as a POP account. I set up a new IMAP account and turned off the POP account, and things are working fine now, it seems.

No idea why it chose Monday to stop working.

I tried to award you a trophy as best answer and can't figure out how to do that.
