Good Day. I inadvertently upgraded to version 125 using PatchMyPC. After the upgrade the filters are not listing correctly. I search for a filter that I know exists; but it does not appear. When I try to save it under the same name, obviously it complains that the Filter already exists. I'm assuming this will be fixed in a future release. Thanks. Joe T.

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

My Local Folders has become corrupted after restoring from a backup. I can't delete or move subfolders, and can only delete messages by holding down the shift key. Is there a way of repairing this? Thanks.

I just migrated my email from cox to yahoo servers. The cox.net domain is retained.

I had never seen a "bulk" folder with my other domains and was having problems with emails being sent there.

I deleted the bulk folder and it moved to trash but cannot actually be deleted. I also re created a bulk folder. see pic.

Now emails are still going to the bulk folder that is in trash.

Is there any way to fix this?

Thanks

I deleted Thunderbird, than Installed latest version. Now in Thunderbird "Use Primary Password" is clicked so I can't reset primary P/W. Previous P/W doesn't work because there is no P/W there as far as I can see. Instructions I found: "Tools> Developer Tools> Error> etc. There is no "Error" button. Instead I get Incoming Connection (attachment) and an other screen that I don't understand. Can you help please? Thank you Ilio Pieroni

Several days ago, my comcast email said it couldn't connect, and after trying a couple other things, I removed the account and tried to add it back on. When I try to add it as an IMAP account, it pulls up a window that loads for a minute then says "Unable to connect. An error occurred during a connection to localhost." On the thunderbird window where I entered my password, it says "Unable to log in at server. Probably wrong configuration, username, or password." I logged in on a browser, so I know the username and password are correct. I tried adding it as a POP account, and that worked fine, but I need it as IMAP.

Windows 10 Pro Desktop PC I am using Tunderbird for my gmail account. Version 115.10.1 (32 bit) Ever since there was a update (upgrade?) to gmail I can no longer use Thunderbird for my gmail. I don't know if it's at the Thunderbird end or the gmail end.

Here are the messages I recieve: First is on the actual email message and the second is a "pop-up" msg in the lower right of my screen.

Error on the composed message: "Your message was sent but a copy was not placed in your sent folder (Sent Mail) due to network or file access error. You can retry or save the message locally to Local Folders/Sent Mail-Rick.Reckage@gmail.com"

Error message at bottom right of Thunderbird: "Connection to server.imap.gmail.com timed out"

Thank you for any help to fix this. I like Thunderird so I contribute. I want to be abble to continue using it for gmail ifmpossible.

Since the update TB to v115.10.1 it will not connect to server, the server just times out.

BUT If I then login to the server directly from browser and check mail (IMAP by the way) using my web online interface I get emails THEN if I open TB it connects and downloads as it should.

This is weird. It's been checking more than a dozen email accounts for a number of years without errors.

When composing a new email and using the F9 key to list addressees in the defaulted address book, this list does not contain many addresses that are contained in the "All Address Books" (Toolbar icon). The "All Address Books" contains 37 address entries whereas the defaulted address book contains 24. I noticed that the missing addressees are more recent additions.

The height of the viewing panel for emails is far too small. I can only see a couple of lines of text at the most and am unable to reduce the height of the incoming list of emails as previously in order to increase the height of the viewing panel. I have been helped to increase the font size of the overall layout so that I can now read it better but the green button to declare that my problem has been solved tells me that the page isn't working!

Going back many versions now I have noticed Thunderbird fails to download new email messages as they arrive on the mail server inbox or junk folders, until now I have lived with it but I need a solution. If I click on any folder like Inbox or Junk the most recent messages are downloaded for that folder. I have set Server Setting to: 1)Check for new messages at startup (which seems to work) 2) Allow immediate server notifications when new messages arrive (does not seem to work) In the past IMAP did not require periodic checking for new messages, as the server received them Thunderbird displayed them, so I have not set Check for new messages every X minutes. In the past many mail servers did not like auto checking more frequently than every 15mins (not sure if this still applies these days). Are there any other mail settings in Thunderbird that may prevent Auto Download of new messages as they arrive. I have the latest Thunderbird ie 115.10.1 (32 bit) Supernova I have four mail account all on different servers same problem with all. Last time I used MSOutlook (which I don't use anymore) it worked fine so I'm leaning toward this being a Thunderbird issue. Windows firewall set to allow Thunderbird Router set for DMZ to machine just in case. ;>) Am i missing a new Thunderbird setting I cannot find?

I had to reinstall Windows and now I can't reinstall Thunderbird. It says my password is incorrect to my primary email server but it is correct. I use yahoo mail but it is showing the host as att. All of my contact and distribution groups are there.

I am in the middle of creating a new event. If I click on the "Invite Attendees" button an "Invite Attendees" dialog appears with an email address already loaded in the first line. In my instance, this email address isn't mine! It is an alias on our corporate Zimbra email system that hasn't been used for 15 years, but is nowhere in my Thunderbird v102.15.1 client. It also isn't in any of my Thunderbird accounts. Where can I define this?

Can I stop being notified of new updates? I don't even want to hear about them. A registry change maybe?

A previous thread I started requested help for an issue that transpired when I updated from 102 to 115 back in 2023. https://support.mozilla.org/en-US/questions/1424162 After messing with it, I uninstalled the 115 update, deleted Thunderbird folders in my user's AppData folders and reinstalled the last update I knew that worked with the email that Thunderbird was having a problem which was 102. I had turned off auto-updates and got my four email accounts back like I prefer.

Last month I was presented with an update notification that I confused with a Firefox update and installed it. Darn - the Unified Folder in that one email was messed up again. I attempted some settings changed to the folders and it seemed to work. I was not too thrilled with the toolbar change at the top, preferring the small print Menu Bar at top, with Tabs directly under and finally Mail Toolbar at bottom but I resigned to live with the change.

A few weeks passed and the Unified Folder for that one email once again had a couple of subfolders under the account AND ALSO I noticed that syncing with my iPhone and other computers stopped. I was having to delete messages twice. TIME TO UNINSTALL AND FIND 102 AGAIN.

Not a huge deal besides needed to redo the columns to my preferences and I finally figured out the child inheritance to other folders thing with all this practice re-configuring to older versions.

So the question... is there a chance that I can have the new update notification stopped? I don't want to even be notified by way of a periodic popup that I have to be on my toes so I can dismiss.

Thanks, Steve

Suddenly my Thunderbird email will not send out any email I try to send. I have been in contact with my server Tech Support. They have checked everything at their end and all seems correct. I can go through their webmail to my account and that works. I have re-installed the program several times, including backup of the Profile, and deleting it from the C drive, then reinstalling it. I have made multiple changes to the SMTP outgoing server, trying various entries. I have even restored my computer to an earlier "Restore Point". That didn't work.

Nothing will allow me to "Send" an email. Other than that, the program works well. I can receive emails, no problem. I am using Windows 11, 64 bit on a Desktop computer. Any ideas what the solution might be for me? Thank you. Dave Wenger - [edited] @ntelos.net, ph: [removed phone# from public].

Hi, I have Windows 11, Intel processor, 64 Gb RAM, TBytes of SD storage. Lately I have been experiencing issues displaying email with attachments. It is intermittent, but occurs when I display an email with one or more attachments such as PDFs. I have a preview window open to the right of my mail list. If I click on the item in the list I see a properly formatted email in the preview window .. for a few seconds. Without me touching anything, the mail converts to HTML and the attachment is gone. Redisplaying the item goes right to HTML. Further, the HTML has nothing to do with the original message. If I go to my mail server the original item might still be there, but it might be gone. I have not seen a pattern to determine why some are gone. I need to solve this. I don't see this problem described in previous posts.

Attachments: tbird_before.jpg - preview email with attachment (personal data obscured) a few seconds later it switches to tbird_after.jpg and I cannot get the email back.

We are using three locations to send emails from this email address. One of the computers at one home, sometime in mid April, was put into a block of some kind for having a PUP (the best I can figure out, don't really understand this stuff.) We had the block removed and most emails are now going through from that one computer. The other computers never had a problem getting their emails to the recipients. The one computer that had trouble, now has Maleware Bytes and Adwcleaner installed, that's what we did to get out of email jail I guess.

The problem is, any of the people that we attempted to email during the week or so that our email was in jail, even though it is fixed, our emails to those people are not getting to them still. We have to use another email address to get them to receive from thunderbird sent from our one computer.

We are not super computer savvy as far as this behind the scenes computer technology goes and need help so that we can reach all our customers reliably. We did try to identify if we were still blacklisted and saw 1 hit but don't understand how to fix it now that we have the additional spyware type stuff added to our computer. Your assistance would be greatly appreciated.

Thank you

I have seen numerous posts on this forum involving the "Leave Messages on Server" option in the server portion of the Account settings. Many of these posts include responders stating that this option does not apply to POP servers.

If this is correct, why does Thunderbird even include this setting for an account that is explicitly designated as a POP server/account? This is an invitation to confusion and misunderstanding; I have been a victim of this. It seems to me to be a no-brainer to change the code to remove this option from these POP accounts.
