Hey all!

I recently migrated my hosting and I deleted the accounts on my Thunderbird client to set the new ones with the correct new Hosting.

The accounts are working correctly, but everytime I open Thunderbird, it shows me a login request from the old hosting service (which by the way, there is nothing there anymore, i deleted all the accounts and data).

I already uninstalled and reinstalled mozilla and tried to "fresh start" again, but this problem doesn't seem to go away.

Help is much appreciated!

Using Thunderbird on Linux I cannot delete any local folders, when I try to delete them I get more copies of the folders on reopening Thunderbird, after the system says it is "not responding" and I close it down. I have tried several times and now have multiple copies of the local folders I've tried to delete.

Good Day,

For the last few weeks, when using Thunderbird on Windows and writing a draft email, when clicking on the button to create a link, the draft email window freezes. This also happens if I use the menu bar Insert -> Links...

All other Thunderbird windows remain functioning, and I can effectively continue working, but the frozen draft window will remain on screen until closed through Task Manager.

This only happens when creating a Link, not inserting other objects, like an Image. This problem also does not happen with Thunderbird on Ubuntu.

I am running version 115.10.1.

Thanks in advance for any tips that could be of help.

I have had Thunderbird email account for years and now I have problems getting my emails to come through on a regular basis. I have to shut down my PC and then restart to get emails to come through. What is the problem. Thanks, James Craig Herring

I've gone into "sort-by" and tried enabling threading. I've tried checking the unthreaded box. Group job related email still just disappears. I can't find received group email in the trash or in the junk. I can't find any evidence in Thunderbird that the group email was received. If I go to a different email tool, there it is. Thunderbird is broken. If I scroll back in time and accidentally scroll past the date of the first group email, there it is. I can't be spending all day scrolling through months to years worth of email just to find out I got a group email from someone today. This is totally unreliable way to find an urgent work email.

Hi. I have approximately 26 folders in gmail and 34 filters that sort messages from my inbox to the appropriate folder on the mail server. I am planning on rearranging the filters and would like to know if there is a preferred way to optimize them. For example, am I better off having individual filters (say from several health providers) that end up saving respective messages into a 'Health' folder OR should I have 1 filter that looks for each provider in turn (OR condition aka 'Match any of...' ) then moves them to the 'Health' folder.

Not worried about performance, but more wondering if one method is more efficient than another.

Also, I seem to recall seeing in the filter help pages that it is preferable to have local storage for filters as opposed to having the mail server sort them out. Why is that?

kind regards, Kirby

I just installed Thunderbird (working elsewhere) on a Windows 11 machine, and used the 'auto setup' feature. Sending/receiving works fine, but for every message sent:

1. A pop-up appears, which reads 'Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message to Local Folders/Sent-mydomain.com

2. The current command did not succeed. The mail server for account mydomain.com responded [TRYCREATE] Folder doesn't exist. (Failure).

Sent messages appear just fine locally in Thunderbird, and also on Gmail, and they send fine as well, so I just need to disable the incorrect error messages. Thanks for any help (NOOB level tech savvy).

Seems after the latest update Thunderbird will not receive some emails. It has stopped receiving emails coming from some cell phones and some .com emails. Some cell phone emails work and others that previously did do not anymore. I do not understand the random situation. No settings have been changed nor is there any setting to correct this. I even reinstalled Thunderbird.

Any suggestions would be great. Thanks

When I click on the arrow to acquire any emails from my isp it will often say downloading 3 emails or 5 emails or some number, but only one or two come in. I have to hit the arrow again to get more. Sometimes it will say downloading some number of emails, but NOTHING comes in. I don't remember this happening until about a month ago. Can you help?

Quite often I find that Thunderbird is very slow to obtain a connection with my Outlook account. I can run my Outlook directly and everything is updated in about 20 seconds and at the same time it may take a couple of minutes up to a few minutes for Thunderbird to complete downloading. Additionally, many times during this lag in connecting, I receive a message that the password is incorrect, which is bogus; all I have to do is select "Retry" and the download process continues. I am using the latest version of Thunderbird "115.10.2 (64-bit)." This problem has been occurring on previous versions as well.

My email was converted from Cox to Yahoo by Yahoo on a system wide conversion on April 27th. In the transition I lost all the emails in my Thunderbird inbox from 4/12 back to the first of the year. I also lost everything in my draft folder.

Carbonite did a restore of the default file (that was dated 4/8) by couldn't get these back. Need to get everything that was in the inbox and draft file on 4/26 (or sometime prior) What can I do?

My Yahoo IMAP account in Thunderbird no longer has any email showing in the Sent folder. There's plenty of mail in Yahoo Sent mail in the browser, but it's not finding its way into Thunderbird. I tried the Repair option, but I just get a typical message that I often see for Yahoo:

"The current operation on 'Inbox' did not succeed. The mail server for account Yahoo responded: [SERVERBUG] UID FETCH Server error - Please try again later."

The Yahoo account shows Sent mail in my iPhone. The Thunderbird Sent folder was seeing messages as recently as last week, so this seems to be a new problem, and I don't know if it's something that I did wrong by mistake. Thanks for any help.

I am trying to do a mass mailing in Thunderbird to about 2015 libraries, with another one to come. I followed all the instructions carefully and generated all the messages and they went into my outbox, with a "send later" command. Then this morning I entered the command to empty the outbox. I immediately began getting an error message that I could only send 50 messages an hour. Feeling like the sorcerer's apprentice, I closed thunderbird, whcih stopped the bleeding. Now I have 1350 messages in the outbox which thunderbird did not try to send.

Fixing up this mess is going to be complicated, particularly with respect to the messages it did try and fail to send (about 750 of them.) But I could make some real progress if I could figure out how to send 50 of the unset messages at a time from the outbox. I have the first 50 out of the 1350 selected right now, but I can't figure out how to get them sent. HELP! Thanks in advance.

I sent an email with multiple BCCs and no CCs or TOs, I put myself as one of the BCCs.

I did not receive it and I do not think anybody else did as well since I asked a few people.

The email is in the sent folder. I tried forwarding the email from my sent folder to myself as CC, and that worked. I also tried fowarding as BCC, and that worked.

So what is going on? Is BCC working? How can I know for certain? Do I need to foward the email as BCCs to all my BCCs to get this to work?

Thanks for your help.

When I try to open and email link, it immediately starts to download Firefox Installer. It is already downloaded and up-to-date. This has been going on now for almost a year. Please help me.
