Thunderbird Support Forum

Thunderbird seems to be hung up in a circular reference. It continues to download 1 of 2 and 2 of 2 repetitively, nonstop. This is continues process without ceasing. It seems be slowing do the whole system.

Each time I open Thunderbird email, a page on firefox opens requesting a donation. This has been going on for weeks. I reached out to Thunderbird, and all suggestions have failed to resolve the problem. Most recently I was instructed to submit the problem here. I hope this is sufficient for requesting assistance. I would like to forward our list of communications and cannot discover a method to do so. If you send me an email address, I can give all that information. Thanks, Norma Bauer cabauer@northlink.com

Since Thunderbird was upgraded to 115.10.1 (64-bit), it now fails to send SMTP messages with the following error.

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) ***.mail.pairserver.com was lost in the middle of the transaction. Try again.

This affects all six(6) accounts in Thunderbird, all of them can receive and edit e-mail messages; however, all of them fail to send e-mail messages.

Prior versions of Thunderbird have worked with this configuration for many years.

Other e-mail clients such as Evolution do not have this issue and I have confirmed with my provider that Thunderbird is no longer sending e-mails.

Any thoughts on how to roll back Thunderbird until this issue is resolved?

I'm having problems with the Cardbook add-on but it is up to date based on my version of TB. When I go into Preferences->Advanced-> Update 'Check for Updates' shows I'm up to date. However, when I check archived versions it looks like the last version that worked with a MAC release of less than 10.12 is 78.14.0.

I'm confused if I can upgrade to 78.14 and how I would do it?

Thanks for any advice

P.S. and yes, it's a very old Macbook from 2009.

TB won't set up on Yahoo mail. Spent about 3 hours on the phone with one and sometimes two Yahoo techs and giving them total access to my computer so they could set up TB but could not get it working. It was eventually suggested I contact you folks, so here I am. When sending an email, it just keeps running like it's sending but doesn't stop. Eventually displays the following:

Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp.mail.yahoo.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

The techs and I went around an endless loop of re-entering PW and checking authentication settings. Any suggestions?

For some reason now, every time I go to type a response to an e-mail, the program loads hundreds of lines of text below my earlier sent message. Need help as to how to fix this problem ?

I updated Thunderbird to version 115.11.0 (64-bit), in the old version that I had when I clicked on an email with threads in a closed state, I could see in the email display box the initial text of each email in the thread with the sender's information and more, in the new version I don't see anything, the display box remains blank. Is this a bug, or do I need to change it in the setting?

I've used Thunderbird for many years and occasionally a message I've sent takes ages being saved, then finally it isn't. This has become more frequent recently together with having to re-enter my email password. I use Ubuntu (22.04.4 LTS) so I don't use anti-virus software and I don't use other email clients (only Thunderbird 115.10.1 64 bit).

I sometimes briefly lose my internet connection, though seemingly not when the email malfunctions, so could my old BT hub be the source of the problems? In the absence of any other solution maybe it's time to get a Chromebook and see if that's any better with Thunderbird. Firefox also now freezes a couple of times a week (and not being an IT wizard I hate not knowing what incantations to type into the terminal when anything goes wrong.)

When I view emails with photos attached inline (both in preview pane and fully opened) i can't see the images as they are massive and go way off the screen. Is there a setting to provide some kind of sensible default so the images are sized within the email i am looking at, so i can view them without downloading and opening in a photo viewer? thanks

upgraded to Windows 11 , and thunderbird has not worked since then !

I am a Senior person who needs to speak with a real person.

PLEASE call me in Sydney Australia, or send me a local telephone number of someone who can help me !

Once you add a new account, you have to race to open up the settings and turn off the "Download all mails" setting that is hardwired as the default. Even after having done that, I am left with GB of copies of mail messages that I don't want to store on my local system.

How do I get rid of those local copies? Compacting doesn't seem to do it - there's no "Compact now" button in any case. I don't know what "when it will save over N MB in total" means, exactly. Save compared to what? Now 50% off!

Likewise, if I have Message Synchronizing (Keep messages in all folders etc) turned off, but Disk Space - Synchronize all messages locally regardless of age is still selected, is it going to download copies anyway or no?

If it will download anyway, or if it already did download, if I change the Synchronizing setting to "only the last 30 days" will it remove the older local copies? When?

The only "recover disk space" option deletes both local copies and originals on the remote server.

There really should be a "purge local copies" action available in the client. It may be that it is OK to go out to the OS and remove certain files myself, but maybe it won't be in the future. Every note that is about "Simply open a Terminal window..." describes specific files that don't quite match what I see here in May of 2024 on a Mac. But the tool itself knows what can be removed safely.

Just a few days ago, one of my email accounts is unable to retrieve emails and it has the following error message:

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 installed the latest updates but still having a problem on that one account. Other accounts I have on the same server has no problems retrieving the emails so it has nothing to do with "disk space". All settings in the accounts are identical except for the email address so it must have something to do with TBird itself. I know it's not the email server as I can log into those accounts using the browser on their website. Thanks!

Upon startup, top email displayed is the 2nd email present in the inbox. If 1st email is one at top when leaving TB, next startup will show the 2nd email on top. You can then scroll up and see the top one. Likewise, if a new email come in, it also shows the one below that as the top one and must scroll up to see it. No emails are lost, just a display thing. Don't recall which version this started, but it didn't use to do this.

TB 115.11.0 (64-bit) Supernova, Windows 10 22h2

My Thunderbird cache is using a gigabyte of disk space. I'd like to clear it, but it's not clear to me if I would be wiping out stored messages when I do that.

I like to download my emails to my computer (and keep copies on the server, too). I thought that was what I was doing, since I can view my emails when offline, but maybe I'm just accessing the cached copies?

Will I lose my old emails if I clear the cache?

Upgraded my Ubuntu server from 18.04 -> 20.04 and now I'm getting this error message "Unable to connect to your IMAP server. You may have exceeded the maximum number of connections to this server" from TB on my desktop. I've tried reducing the number of cached servers, and restarting my phone and nothing works.
