Using Thunderbird desktop for Windows with my Hotmail account, I frequently cannot send an outgoing email. I regularly get the following message even while successfully receiving incoming messages.

Send Message Error Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Cannot connect to SMTP server 2603:1036:308:2817::2 (2603:1036:308:2817::2:587), connect error 10060.

I use Thunderbird for Android with the same email account without any issues. Any thoughts?

I have no idea why, but TB is wonking out lately with strange errors?

The folder '[Gmail]/Sent Mail on me@mydomain.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again.

I have a ton of space and have not changed anything on the PC?

Any ideas?

I am not receiving emails from my laptop, but i do on my iphone and ipad. I have had to change my password with Telstra so do I have to change my password and if so how do i do it?

Auto configure does not auto configure. can get texts at [edited phone# from community support forum]

I believe incoming mail is POP3 and Outgoing is IMAP on Spectrum server in Utica NY

Or it was before Thunderbird did this update.

I recently moved to another email provider. Since the move I use a new email address (account). The mail in the previous used imap account must be saved. Since the old server at the provider has been blocked. A lot of emails have to saved for some years. Do you have a suggestion how to save the mail? Thanks, Paul

Been using and loving Thunderbird for over 10 years - now on 115.18.0 (32-bit) with 8 different email addresses, all on 'ionos.co.uk'. My AV is Norton and seemed to 'upgrade' to 'Norton for Gamers' 2 days ago. Since then attempts to read messages get a pop-up window titled 'Add Security Exception' with text 'You are about to override how Thunderbird identifies this site. Legitimate banks, stores will not ask you to do this. ' It gives location as 'imap.ionos.co,uk;993' then a line says 'This site attempts to identifiy itself with invalid information'. Clicking button marked View shows details that include 'Organisation: Norton Web/Mail Shield' hence my suspicion. I've had a lengthy call with Ionos support, very patient and helpful, checking things at their end, concluding nothing of theirs has changed and all is working correctly. I tried one of the addresses using their webmail, which worked perfectly. About the same time that this happened, I started getting pop-up messages from Norton when I started software programs that I wrote myself some years ago. That's never happened before! Tried reading Norton help pages but cannot get hold of a human. Has anyone else had this problem? Should I ditch Norton? Many thanks!

After updating to 137, trying to send emails times out for my GMX email, however for Gmail it still works fine (I attached the console output in safe mode). I am not using a firewall or a proxy and the problems persists in troubleshoot-mode. I am using Manjaro with Kernel version 5.10.234-2.

I accidentally dropped my "Bulk" folder in the "Trash" folder. When I tried to remove the folder, it refused to move!

1. I tried ctrl + Z to undo the last action - failed
2. I tried dragging and dropping - failed
3. I tried right-clicking and choosing move - no such option - failed

I tried closing the program, reopening, and repeating steps 1-3 - failed I tried rebooting the computer and repeated steps 1-3 - failed

How can I move the folder back?

I have 7 folders in my Thunderbird (128.9.2esr (64-bit)) "Favorite Folders". The last folder keeps disappearing. When I right click on that folder in the "All Folders" tree, the favorite folder is checked. If I uncheck it and recheck it, it then shows up in "Favorite Folders" again. It disappears at least once each day. Any ideas as to why this might be happening?

Before the last Firefox update, I was able to view jpeg attachments in emails (before and after sending) in Windows phot viewer - now I can't!!?? The options it offers to view are weird - adobe, media viewer etc - rather than before where it was Paint, Picture viewer etc? - and in settings, the ascribing options are the same, and I can't find any other on offer? How can I ascribe something like Windows picture viewer to attachments? (I have managed to get t to accept Photoshop - but that is a slow-opener) Mike

To recap: I have been using Thunderbird for years. It receives 5 email channels and was working fine up until a few weeks back. I can still use it to send on that channel just not receive. Since it is Imap I can access it ok on the network providers web site (Talktalk) I can also receive it ok on an Amazon Fire tablet. I have tried turning off aspects of my antivirus (Bitdefender) but it doesn't seem to help. At the bottom edge of the Thunderbird screen I can see various sets of words which seem to indicate it is accessing the Imap channel just that nothing appears. In case it helps the email address is of the form xxxxx.xxxxx@lineone.net. Someone helpfully provided a list of suggested problem areas but they either don't apply or they seem to be ok.

Thunderbird email is not displaying "some" individual emails in pop-up email windows. I get a list of emails that have come in, but when I select some of them to see their contents, they show a blank box with absolutely no content. This only applies to some emails, not all. The others display their content with no problem. And it's not always the same senders that exhibit the problem. It is totally random. I want to fix the problem since I cannot read all my emails. I did a "repair" on Thunderbird last night, but that scrambled everything, so I had to restore my PC to its last backup date, which was fortunately the day before.

I've been using Thunderbird for years without issues. A few weeks ago, Thunderbird on two of my computers, (a Win10 laptop and a Win11 desktop) stopped receiving email, but were still able to send it. After a couple of days, normality resumed and both computers were able to receive email again, without any corrective measures taken by me. However, about 5 days ago the same thing has happened again, but this time, the desktop has resumed normal function but the laptop has not. The error (both times of failure) is shown in the image. TB on the Win10 laptop is configured POP3. On the Win11 desktop IMAP.

Email works perfectly from web interface, and so I'm very reluctant to change the password on the server in case I get locked out of the web interface, but perhaps this might be the step to take? I uninstalled TB using RevoUninstaller to completely wipe TB from the computer, including any registry entries. Installed TB version 137.0.2. Still the issue persists. I'm certain that the account settings are correct, so the issue is a complete mystery to me as to what is going on here. I would very much appreciate any help to resolve this issue please.

While looking for another setting, I noticed that a setting about how T-Bird handles spam mail. I have it checked. Today, I received a DOOZY of a spam mail, but Thunderbird didn't flag it. It was so obvious spam, as it asked for credit card, banking, automobile license! Also, the Subject asked to update payment info, but the From field wasn't that company.
