Whenever I reply to an email, Thunderbird inserts a detailed email header above the message to which I am replying. How do I minimize that info to Date-time, Sender, Receiver, and Subject?

This evening, Thunderbird has updated to the new version (can't see where the version number is held, unfortunately). Whenever I try to download new emails, I now get the message "Error with account [email address]. Sending of username did not succeed. Mail server pop3.iomartcloud.com responded: Mate, the command must be one of CAPA, USER, PASS or QUIT." Mails are still accessible through the mail client on my phone and through webmail, just not through Thunderbird.

I accidentally deleted a POP account and I lost every folder that I had on that account, how can I recover it?

I tried with some recovery programs but it didn't work

I am currently on Ver 115.12.2 (32-bit), but I've had this problem over several versions. I recently downgraded from the 64bit version (for a different reason), it had the same issue.

Old messages in the Inbox are listed twice, including those that have been read. New incoming messages are not duplicated, messages where I've deleted the duplicates are not again duped. Messages that get filtered to or moved to folders are not duped. Old messages that are in folders are not duped.

I have several email accounts in TB, and I only see this on my most active- of course! I have compacted all folders many times and rebuilt the Global Database with no effect. I tried opening in Troubleshooting mode and they are still duplicated. It is a POP account.

I cannot receive or send any emails. Server is not authenticating. This is a sudden fault. Thunderbird is updated to 128.0.1esr (64-bit). Opening Thunderbird shows message "Authentication failure while connecting to Thunderbird imap.gmail.com”.

What is the fix for this?

When I click the button to “repair a folder”, some e-mails have disappeared.

The inbox file is too heavy and cannot be opened as a text file.

I moved the defaults file to an external HDD and saved it over the defaults file on my computer. I could not restore them.

Is there any other way to recover my email?

Hi,

I'm using Thunderbird 128.0.1 on Mac OS 14.5, and recently (not sure when exactly), none of the normal messaging options like reply, reply-all, or forward are available. I still can start a new message, though.

Thanks.

I update my Thunderbird yesterday afternoon to the newest version. Now when I click my icon to launch it it launches a second default gear icon with the hover text reading "thunderbird-esr". I purged the install and reinstalled with the same issue. I'm using Pop!_OS on Wayland if that helps.

Since we upgraded to 115, most of our PC cannot forward email larger than 5MB to team members. One or two PC can sometimes send without problem but not always.

We can press "forward" and the compose new email window comes up as it has always been. But when we press "send", it will stall for a while then responded "Cannot send email". Press "OK" and sometimes it will then respond "Creating email" or something like that. The sequence could be reversed (create first then cannot send). Cannot even save as Draft into the Draft folder on our own manged MDaemon mail server on our local LAN.

Thinking it is all due to the forwarded email being too big, tried many many times over weeks checking MD setting, LAN and individual local PC setting but still cannot resolve.

Today I tried something completely different. Instead of "forwarding one large email", I tried to attach large attachments like .jpg etc and found that it is the "attachment process" that is causing the problem. If I attach a larger file, say 10MB, it is problem. If I attach several small files, it sometimes go through even the total file size exceed 10MB. The I tried attaching just a few attachments, save to draft folder, close the compose window, re-select the draft email and then add more file. Repeating this several times I managed to be able to save to draft folder on the server and then send out an email of 49.9MB. I keep on playing with it for hours but I could repeat and can only managed to do something like 10MB/11MB.

This is still much better than trying to "forward an email" (as attachment or in-line) which we can only do up to about 5MB max.

Please help to resole this problem.

Thunderbird 128.0.1 Nebula just updated. Now it freezes up when I try to open an account's Inbox. The main interface page shows messages in an account but when I go to the account and click on the inbox Thunderbird freezes up! I never had this problem with the previous version. I have multiple accounts with multiple services and it hangs/freezes on every single one. Sometims if I let it sit for several seconds, it will open. Other times I have to close Thunderbird and re-open it to check the inbox.

Is there any way possible to revert back to the previous version? This is horrible! I absolutely HATE it!

Have no clue what I am doing. I have downloaded Thunderbird so I can access my bt internet emails (webmail is having issues)and have fallen at the first hurdle! I need someone to put in easy words what I am to do please. I have inputted my email address and password and it says unable to log in at server.

Hi all, I am a long time Thunderbird user on all my Windows machines. Today I installed Thunderbird 128.0.1esr (64bit) on fresh Win11 machine. I successfully added my gmail account to Thunderbird. I have issue with my other account - the SSL cert is issued not for this specific domain and I get warning about this but I can't accept this as exception - it appears again right after clicking "accept exception". I know this is about SSL cert but I want to accept this exception.

On another Win machine I had configured both accounts for ages - it stopped to connect to this server right after upgrading to 128.0.1esr.

Disabling SSL scanning in ESET or disabling protection at all is not helping. When I change configuration from "STARTSSL" to "NONE" it then connects to the server. The issue is with accepting exception in Thunderbird. Do you have any suggestions?

Kind regards Daniel

I use thunderbird on two desktop computers that are linked via google. Last year or maybe year before I started getting a duplicate email problem. If I send an email from one of the 5 email addresses that I use the email is sent to the intended recipient but, it is also sent to the inbox on the other computer. This week because I was having a signing in problem I have reinstalled mozilla thunderbird on both computers and also deleted the email addresses and re-created the accounts for them. The sign in problem seems to have been cured but not the duplicate problem. Anyone have any ideas about this? Andy

Hi This is not the first time I am getting this issue. I have among many email accounts from diverse providers 2 Outlook & 1 Hotmail email accounts. For some reason, in the last 2 weeks, Thunderbird stopped automatically logging in, although I have not changed log-in data for any of them. If I try to sign in the provided Thunderbird log in box, it rejects the log in. Even stranger, after running Thunderbird in the background in the last 2 hours, like today, SUDDENLY & without warning, I get alerts of new mail in the Hotmail account. This also happens for the Outlook accounts, which show new mail having come in yesterday and the other day, although as of now, unlike Hotmail, the other 2 have not subsequently logged in yet. I can log in via Firefox into those accounts, but Thunderbird will not, at least at the start of Thunderbird, but at a time later I have no control of? What is this strange behavior affecting only Hotmail & Outlook and how can it be permanently corrected?

Thank you in advance

I suggest you stop recommending Mailfence. I have had some issues recently with my emails and presume it is to do with various updates, but the Mailfence account which i was going to close at the end of the term, remains blocked and i can't recover anything from them. Thb stated it was free when i subscribed, only it wasn't free for Thb platform users. They are not a fit company
