Thunderbird Support Forum

I can receive emails to my (protonmail.com server) email account on Thunderbird. But I cannot send emails. This is the error message. "Sending of the message failed. An error occurred while sending mail. The mail server responded: Error: no such user. Please check the message and try again."

Thank you for your help!

OSX 12.7.4

I upgraded to 115.9.0 to get OAuth for some, but not all, accounts. Those on Gmail & Yahoo are OAuth. I have non-OAuth accounts on a Zimbra server, and on Panix.com.

It prompts for the first account's password. TBird then gobbles all available CPU on the machine, and stays there. If I wait long enough, it becomes usable again, but that may well be hours.

However, once it calms down, it works normally.

Intertwined with this is: TBird rejects the Zimbra passwords as I enter them. I retry and retry, and then they succeed. I know the passwords are correct; I've even typed them out, and then copy&pasted them in. I'm not sure about the Panix account, if its password works the first time or not.

I tried restarting in troubleshooting mode; it made no difference.

I can't use Thunderbird any more. I open an email and I get 7 copies up across the top of the screen. Delete does not get rid of them, and I am up to over 50 at this point. Please contact me directly at [removed phone# from public support forum] when you have fixed this. For reasons I have just outlined, email is not a good way to communicate.

I assume that everyone else is experiencing this disaster.

top - left "get messages". either the button or on the account right click and get messages.

its been one or 2 days now that i press either and also on TWO DIFFERENT PC running win 10 and 115.9.0 version and nothing happens! doesnt get any messages. dont even get the Checking notification on the bottom left. auto message retrieve doesnt work either no matter the time period. its like i am clicking on empty space... a while after, just by itself, it starts downloading again.

Since applying update 115.10.0, Thunderbird will not close correctly and will not relaunch until task is ended in task Manager. This is true on a windows 7 PC and windows 10.

How do I go about fixing error message regarding Incoming Mail: UID Fetching Failed

I tried support page, but all threads archived. Not sure how to proceed? Be kind too as I'm also pretty old!

I see that there are 9 messages...Tried tools, checked account settings and couldn't find anything.

Your help would be greatly appreciated. Bad day. My sink is stopped up too!

Start new Windows session. Start Thunderbird and works OK. Shut Thunderbird down and try to re-start during same Windows session and it will not launch. Reboot Windows and try to start Thunderbird and works OK. Alternatively, going into Task Manager there will be a number of Thunderbird processes running. If I manually end them all (while Thunderbird is NOT active) then I can restart as normal too. This all began with 124.0 Beta 1. Never had the issue prior.

Also, Thunderbird crashes if restarting within the app. By this I mean clicking the X it appears to close (excepting those persistent processes running) but "Restart Thunderbird" such as to launch Troubleshooting mode or from the "Restart to update Thunderbird" config crashes the app with 100% consistency.

I want to setup my Gmail account that my school hosts. It has a unique domain name and Thunderbird does not recognize it as a Gmail account, but I'm sure it is. Here's what I did to solve the problem (yet no luck) First, I tried to setup with manual IMAP configuraiton by following the steps on LifeWire Article and Google Support, but it says that credentials that I'm using is wrong. It did detect the Gmail mail server though. Next, I tried to pretend that I'm going to login as a user I've created ON GOOGLE so thunderbird can recognize it as Gmail Account, then logged in with my school credential, and it failed. Probably because I've entered fake Gmail address in the form. It's very inconvenient that I cannot setup mail accounts with OAuth authentication method manually.

Do you have a walkaround for this?

Title. Thunderbird is a really cool client but it's pretty slow. I blame that on the thousands upon thousands of emails that my hotmail and gmail each hold. I don't necessarily want to delete these emails, but I have seldom a reason to have any email older than 2 months in my thunderbird client slowing and crashing the program whenever I want to combine inboxes.

To this end I went to "Synchronization & Storage" and told it to "Synchronize the most recent 2 months" but it didn't delete the huge cluster of older emails. The next option is to tell TB to delete these emails in the same menu but as I understand it that would also delete them in the server, which I don't want to do for posteriority.

What do I do?

Have used a Onetel e-mail account for a number of years.

Occasionally, the outgoing server drops out so messages can't be sent only received.

When trying to reconfigure with correct port numbers etc it will never reconnect straight away and there is always a long process to get it up and running again which always seems different every time.

I can never manage this by myself and always have to get help in. This has baffled the best brains in the business so any help or advice gratefully received.

For the last 6 months, my ip gets blocked from my website server about once a month. This causes me to locked out of my website until inmotion unblocks my ip. It works fine for about a month and then ip blocked again The conversation below was with my hosting company Inmotion hosting

4:35:48 PM) Andrea J.: Looking at the error, I can only see failed logins for alan@wood-r-us.com. (4:36:02 PM) Andrea J.: I have unblocked the IP for you. (4:36:16 PM) Andrea J.: So you should be able to access the server now. (4:36:54 PM) Alan Johnston: Yes my email is working again thanks. (4:36:59 PM) Andrea J.: My pleasure. Was there anything else I could assist with today? (4:37:20 PM) Alan Johnston: What can be done so this does not keep happening about every month (4:38:32 PM) Andrea J.: You will need to locate the device that is having the login issue, (4:39:14 PM) Alan Johnston: That is the only email related to this site and It is me. I use thunderbird and I stay logged in all the time (4:40:11 PM) Andrea J.: Mar 13 15:49:30 ecbiz320 dovecot: imap-login: Disconnected: Connection closed: read(size=720) failed: Connection reset by peer (no auth attempts in 3 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85, TLS: read(size=720) failed: Connection reset by peer, TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) Mar 13 15:49:31 ecbiz320 dovecot: imap-login: Disconnected: Connection closed (no auth attempts in 0 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85, TLS handshaking: Connection closed Mar 13 15:49:31 ecbiz320 dovecot: imap-login: Disconnected: Too many invalid commands (no auth attempts in 0 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85 Mar 13 15:49:31 ecbiz320 dovecot: imap-login: Disconnected: Connection closed (no auth attempts in 0 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85 Mar 13 15:49:31 ecbiz320 dovecot: imap-login: Disconnected: Connection closed (no auth attempts in 0 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85, TLS: Connection closed, TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits) Mar 13 15:49:32 ecbiz320 dovecot: imap-login: Disconnected: Connection closed (no auth attempts in 1 secs): user=<>, rip=172.58.1.223, lip=209.182.196.85, TLS handshaking: Connection closed (4:40:37 PM) Andrea J.: Looking at the server, the logs shows connection errors. (4:40:56 PM) Andrea J.: You may need to look into ThunderBird to see if there is an update that is needed.

My emails have large a lapse in time before the downloading catches up. For example right now my last email showing says 6:41 PM when it is actually 9:44 PM. This is costing me sales on items I have listed on the marketplace because I have no current notification via emails. Please help.

Hi there,

My grandmother on this account keeps receiving a enter primary password alert on her Thunderbird / Bigpond account. We've tried everything and when following the prompts to reset (tools > developer tools > etc) it won't come up with the evaluate button or reset button. We've tried the online sources but no success and she can't access her emails on her desktop. Please let me know what we can do !

Previously, for years, selecting and deleting groups of emails took only seconds. For sometime now, the more emails selected to delete as a group causes the amount of time to do so to become longer and longer. Minutes go by. It feels like instead of dealing with all of them at once, it's deleting one at a time, but that's just a guess. What can I do to get back to where it used to be? Thank you.

I am going crazy. This message keeps popping up every time I turn on my Thunderbird email program on my Windows 10 laptop! Please see the attached file. I shows you the popup and what happens when I click on 'Next'. I 'x' it off, and a few seconds later it pops up again. The only way to stop it from doing so is to turn off my Thunerbird program. I like to keep it on so I know when I get emails. PLEASE help me get rid of this. Thanks so much.

Everytime I open thunderbird it gives me this message 3 or 4 times: Some folders (e.g. 'All Mail on ebailey@phillipslaw.net') cannot be compacted because there is not enough free disk space. Please delete some files and try again. I have deleted thousands of emails and it still sends this message

for last 3 days Thunderbird has become very slow , after clicking on a message it will take very long tie to read. when I select a message it remains unread. Typing is also very slow .

When I start T'bird in normal mode, I get what you see in picture #1. Notice the custom menu bar at the top. I can still receive emails into the Inbox (but can't see or access them), and I can write an email, access the Address Book, Calendar, etc.

When I then start in Safe mode, with Shift key down, I get what you see in Picture #2. Notice that the custom menu bar at the top is gone. I have to recreate it every time I shut down and restart T'bird. That is unacceptable.

Please advise what I should do to correct this situation. If I can't, then I'm through with Thunderbird (after some 15+ years).

Many thanks, Robert Hawkins
