One of my email accounts will not connect. It was working but has not connected for two days. The message says log in failed for rosemarierussell33@yahoo.com.

Thunder bird version 140.10.Oesr on iMac desktop. Just stopped DL mail. Asked me to sign in; shows my user name. When I click NEXT it goes to a blank page and say "too many trys" Next dy; say on first attmpt.

When checking for new email a pop asking for the username and password of the for the email server. Also when a separate email client is downloaded. This only happens when. using a mac book pro. No problem when. using Ubuntu.

Hello,

In my Thunderbird Profiles folder, I can drill down to ImapMail. I see multiple subfolders prefixed with my imap server name. eg:

- imap.server-5.com 10.85GB - imap.server-3.com 8.83 GB

and so on. The datestamp on each is different.

Within the two examples above is a large Inbox folder taking up ~8.8GB.

The size doesn't concern me as much as the fact of having two of these. I'd like to understand what Thunderbird is doing under the hood here. Does it create new imap.server-#.com folders periodically as backup/recovery folders?

I'd like to recover space where possible but if these are protective measures, I could live with that. However, if it creates future folders and replicates 8+GB of data multiple times, I'd like to know what steps I can take to free up disk space.

Thanks,

I seem to have caused my emails to disappear completely. I cannot find them anywhere on my macbook. I don't think there has been anything unusual from outside sources.

I fully expect that I am the cause of it, I am getting old and my so are my eyes and fingers.

For the last 2 days or so, I cannot receive emails in Thunderbird from my Comcast email account, The app receives from other accounts. The app also sends emails from all my accounts, lets me read already-received messages and move the messages to other folders as it usually does. I just can't receive emails from Comcast/Xfinity. I note that Thunderbird had a update a few days ago.

My computer has not worked for nine months.

I've been looking at my e-mail on my phone (not in Thunderbird for Android, which pretended to send my messages but didn't). I want it on my computer.

I didn't want to do that right away, but it looks like Thunderbird started doing that automatically when I launched it. It successfully got my small account, of course, but not my big one.

It's been stuck on this for more than 12 hours. (See image. My apologies, I've forgotten how to embed them.)

Is it safe to shut the process down? Whether it is or isn't, what do I do next?

My computer is a MacBook Pro (13-inch, Mid 2012), running OS X.15 (Catalina), with Thunderbird 140.0.1esr (64-bit). The process started before I could upgrade to 149esr.

Thank you for any help you can give me!

UPDATE, 4/11, 8PM EDT: No change. . . .

Hi there. I'm looking for a shortcut that takes me from the folderlist pane to the message pane and the first new message, when I'm on the inbox folder. The tab is not good. It moves between to many fields/options.

regards bjarne

Thunderbird (actual version) is demanding constantly for caldav- and carddav authentications although the two mail accounts are deleted in Thunderbird. How can I get rid of these annoying messages?

Hello,

I had an issue with my Thundebrid 148.0 (aarch64) running on Mac OS Squoia. I am using it since 2012 and had no issies. But last week when I was trying to empty the trash in the app, it got deleted everything! I had my saved local folder intact. But all IMAP data was errased. Luckily my hostng company were able to restore the back up, but I lost almost a day of emails. Please look into that issue and let me know.

Thank you Alexey

It would be great if you could help me restore the view and, consequently, access to my email accounts in Thunderbird under the circumstances described. Thank you!

good morning , I am using a mac mini 8 gb ram and the latest ios, avg antivirus and vpn. Following the latest ios update in feb/2026 thunderbird opens then locks with a rotating color circle and force quit is needed to close it. Emails are via the imap and smtp protocols, with both not being recognised by the server. Can you help, I need access to files from thunderbird. Can this be done offline, avoiding the server problem. thank you for your help. Jeff

Thunderbird 128.14.0esr (64-bit) on an M3 Macbook Pro running Sequoia 15.7.4

I have my own domain and email hosting. I recently changed email hosts and am seeing large files in my profile tied to the old email host. I'd like to recover 30+GB if possible but don't want to do anything hasty.

My Library folder looks like

Thunderbird - Profiles -- myprofilename.default-esr --- oldemailhost.com --- oldemailhost-1.com --- oldemailhost-2.com ... --- oldemailhost-4.com --- newemailhost.com --- newmailhost-1.com ... --- newemailhost-4.com ... etc.

The oldemailhost*.com files take up ~30GB. Can I recover that space without hurting anything?

Thanks.

I recently replaced my Mail with Thunderbird. The left pane successfully loaded my mail folders but now I want t create new folders and insert them alphabetically. How do I d this?

Why am I not able to add a 3rd IMAP email account?

Everything comes up like before for IMAP accounts, but it does not recognize the email or password, for some reason, and I have checked them over and over.

I also tried adding manually, but although it adds the email account name, the connections don't work, and there is not much information to even adjust that.

Message sent has red texts (all containing an hyperlink). When vizualized in Thunderbird they all appear in blue. When vizualized in Gmail they appear in red! Texts written in red in Thunderbird messages still appear in black in draft's message!

Have been using Thunderbird and Firefox for decades, naturally, and have several email accounts. Within each account, I'm a prolific user of folders within the respective Inboxes. For years, these folders have remained in Alphabetical Order, as when they were set up. Recently, however, for no reason that I can suss, the sub-folders in the Inbox of one of my accounts have been gone "all agley", ie. they're listed all higgledy-piggledy in random order. This isn't a problem for my message filter - but it's a real problem for me, having to scan down a very long, disorganised list to find any particular folder I want to open. I've searched for an instruction to instruct Thunderbird to arrange the Folders in my Inbox in Alphabetical Order and can't find anything. Can anyone help me, please. Many thanks in anticipation to all you helpful Thunderbird Users and Contributors. Cathleen (London, UK)
