When I try retrieving my email from my AOL account (IMAP) using Thunderbird and Windows 11 I get the message "Authentication failure while connecting to server imap.aol.com." This account was working fine for months until the T-bird update. I have several other accounts on T-Bird, including Gmail and others, and they're still working just fine.

I have double-checked all the account settings and tried deleting the AOL account from T-Bird and setting it up again from scratch, but the problem persists.

Please help!

Many thanks.

You updated to version 148 yesterday, or close to it?
