Thunderbird Support Forum

Periodically I am unable to delete emails. I usually just highlight the email, then click the delete button. When that stops working, sometimes I can use the Edit menu and delete the email that way. Other times I cannot delete. If I come back later, I can usually delete again. How can this be fixed? Thank you.

I am a very long-time Thunderbird user. I store my e-mails in many folders, and in all folders I have the unread highlighted. In my primary, very large inbox, the total number and the number of unread messages are normally displayed, and in the message list, the unread are highlighted. I was using a filter for something else totally unrelated, and suddenly I began seeing only total e-mail number, and the unread are no longer highlighted. The unread are still highlighted in my other folders. Is there some way to get the unread messages in my primary inbox marked again? Otherwise I often don't know which to read. I'm talking about thousands of messages, not just a few! Thank you.

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.

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.

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?

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.

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?

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.

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

Hi. My hard drive crashed. I have a new pc and the old drive is readable in a drive enclosure hooked up to new PC via usb. I have done the typical search for the appdata profile file, but I am not sure what I have here. I have attached a screenshot of the old drive and a global search on "Thunderbird". I am not sure where the profile file is residing. Any advice would be welcome. Thanks.

As a longtime user of Thunderbird, I am very familiar with the Address Book. But a couple of years ago, "Cardbook" showed up on my Menu bar. It started out the same as the Address Book, but they are no longer identical. For example, in Cardbook my son's entry has one email address; in Address Book, he has four. What are the differences, and which one should I be using? This is of particular concern to me because I just synced my Address Books between devices using BirdieSync, and it wiped out a very important contact out of my Address Book. Luckily it was still there in the CardBook, but I don't want to lose my contacts in either.

Hi my email address (all services) has been migrated to a new company so I've got a new server name and new imap and smtp port numbers all of which has been duly filled in in the correct boxes (as far as I know). The new server name is mail.mail.coop the old one is smtp.iomartcloud.com. Everything seems to be working ok, ie. there's the new account listed in the left-hand window with all the folders and subfolders and all the emails in the correct places, all working fine inc. send and receive. The old iomartcloud account is still there just above it with all the folders etc. but no send and receive because the service has now been closed by the server company (all my emails have been transferred to the new server. If I go to my webmail page also all is ok inc. send and receive. I have set the new mail.mail.coop as the default and I've been trying to find out how to delete the iomartcloud one.

The problems I have are two: 1. I can't seem to find any way to delete the iomartcloud account from thunderbird. 2. Whenever I close and restart thunderbird it's forgotten the mail.mail.coop account/identity. I have to go to new account > existing email (my email address hasn't changed) and put in name, password etc. It all works fine again but next time I close thunderbird......

I know the server is ok and I know the passwords, port numbers, server addresses, etc. are ok because it all works fine each time I create the new account (for the 50th time!), so there's some other problem I haven't yet identified. I've searched on this forum and elsewhere, and hunted all around the settings menus but to no avail.

I wonder could the two things be connected? If I could delete the old account maybe it would solve the other problem. Note that both the email address, name and password are the same for both accounts, only the server address is different (and the port nubers maybe as well). And could the second problem be to do with the security settings of my browser or os? (brave browser, linux zorin os).

Sorry rather a long post! Hope someone can help me! Justin

I have the Latest Thunderbird 115.10.2. I am running windows 11 pro 64-bit, 23H2 - OS build 22631.3447 I have run the latest downloads (KB5036980) My Mail server is run my Virgin Media. My email account Has 5 accounts, I seperately have an account with Fasthosts My wife has a gmail account and a company email for whom she works, So in total I have 8 seperate account from which I have set to download emails from. All my Thunderbird account ave been set up exatly the same with the exception of which servers they go to to down load emails. All accounts are required to automatically download every 4 mins, I have NOT ticked the - Leave meesages on server and both sub boxes - * so many days and - until i dele them all are unticked. The advanced box at the base of the Server Settings tab, is set to include this server (whiche ever of my accounts server it is) when downloading emails. My problem is that my web email for Virgin Media should receive all email for the 5 account I have with Virgin media. I have not set virgin media account to divert any emails. I was under the assumption that if Ive set up Thunderbird to download all my emails every 4 mins then nothing should be left on my web mail account, or so I thought. Due to my wife not receiving emails to her via 2 of her account, 1. Virgin media 2. her company email. So I wnet onto my web account with virgin media and to my horror i had 999+ in my inbox and had 500+ in the spam box. thinking this was the problem I set about deleting all the emails, 1st i emtied the spam folder in bulk delete. I then proceeded to delet one at a time just in cas i saw some that needed to be kept. The deleted email box hit 999+ minbox was still at 999+, cutting a long story shoert - I deleted of 8k emails, talk about sor index finger, and going cross eyed. My web mail inbox was now clear of emails, didnt last long, so by having my thunderbird open on one screen, I had the web maill account opebn on my 2nd screen. when email cam in some wer downloaded to thunderbird - some were not, even the ones that were down loaded stayed on the server and were not deleted. I checked every account in thyunderbird just to make sure i was not setting thing up correctly, I had. all the incomming mail has been for either me or my wife both accounts are with virgin media. Thunderbird downloaded only one of the emails to my inbox, it did not delet it from the webserver, no has the other 2 sent to me, the one for my wife, not her company email, is still stiing on the server and has not been downloaded. What is going on, its driving me crazy try to resolve a problem that I though I didn't have.

I used Thunderbird for years with my account A, recently added account B. Now messages arriving at account A are quickly moved within seconds into trash for account B. What have I done wrong? Help

I am trying to add a secondary Comcast email account to T-Bird. The primary account was added OK. This is a sub account of the top one.

Note, I have 2 other computers and I was able to add this sub account easily, but that was some years ago.

When I go through the motions of adding my email address and password, when I click "Done" a window pops up with the massage "Secure Connection Failed" The error code is PR_CONNECT_RESET_ERROR.

When setting up the primary account, the little window asked me my password then asked if it was OK for T-Bird to access the account. This was as normal like all the Gmail ones I did.

But it seems this sub account cannot be added.

Any Ideas?

Thanks, Mark.

Thunderbird 115.10.1 (64-bit), no extensions or add-ons Ubuntu 23.10, AMD64 Earthlink ISP and email

Start Thunderbird, go to Drafts folder, open email, click Send, get Send Message Error (see error.jpg) in about two seconds.

There is no request for password, I do not save any passwords. When I Get Messages, a password is requested and I receive the messages. If I try to send after getting messages, same error.

Thunderbird settings are as Earthlink specifies for POP3:

 https://help.earthlink.net/portal/en/kb/articles/email-server-settings

See smtp.jpg. Earthlink user support said to use "Authentication method: Encrypted password". Have also tried "Authentication method: Normal password", got similar error message.

The last time I successfully sent a message was a year ago, this is the first time trying to send since then. There have been OS and Thunderbird updates in between, probably some Earthlink changes too.

Somehow, the "auto-BCC" feature in one of my Thunderbird accounts has been activated. How can I disable that? When I open an email now (in my 'in-box'), it automatically fills in "To" and "From" fields. I no longer get my 'in-message' toolbar in the upper right-hand corner of the message window (tab). I also no longer get the notification that "Thunderbird has blocked remote content..." How can I restore this without deleting and rebuilding the account? I'm sure this was mistakenly activated but it needs to go away!!!

On a further note, I have found that if I move a message from my in-box to ANY other folder, I get the normal message view, with all the correct toolbars and indications and controls! Attached are the correct and incorrect screenshot of the same message, just in different folders.

Thanks in advance for any help that anyone can provide.

Hello, I would be grateful for help onm the two following problems in Thunderbird. 1. When someone sends me a web page link, I click on it and get the error message 0x80070057. I have tried the suggested solutions in regedit but it does not work. 2. When I buy something on ebay they send me an email confirmation with a picture of the item purchased. When I go to print it the image disappears.

I am losing what hair that I have left as I am a senior citizen.

many thanks in anticipation. kr David

Hi folks

When viewing some [not 'all'] PDFs I've created via T'bird's inbult PDF preview on my W10 Desktop PC an annoying black blob in the shape of a car key now appears on the PDF's pages from page 2 onwards. When viewing the same file via an iOS device or inside Dropbox there is no black blob. Also, when viewing the same file via the full Adobe Acrobat APP on my W10 Desktop PC there is no black blob. This black key-shape blob only shows inside T'bird's inbuilt PDF previewer.

I know how to change the preview function inside Tbird to instead open any PDF in Acrobat, but as I quite like the T'bird PDF preview feature does anyone know why these black keys are appearing and how to get rid of them?

Further info: The only PDFs with the black blobs are those created via my W10 Desktop PC's PowerPoint APP's "Save as Adobe PDF" function. There is no such black blob on the PowerPoint pages themselves, and again no blobs appear when viewing the new PDF on any iOS device or within Dropbox. Additonally, and since writing the above lines, I have emailed the PDF to a friend who has opened it on his W10 Laptop and there are NO [again, NONE] black blobs on his screen [he uses Outlook as his email handler]. Thus, I feel certain the problem is within T'bird's PDF preview code.

Is there any fix for this?

Thanks.
