I accidentally deleted an email account on Thunderbird Mozilla, My email person said to just recreate the account and all my information would be there!! it's not I lost all my sub folders and information?? how can I recover my account and sub folders?? Thank you Doug

I have two email accounts with Rogers where I use Thunderbird on my PC as an email client. Rogers recently forced changes to my account to require an an OAuth2 authentication method. Rogers itself was unwilling to provide me with any direction as to how to do that and after much trial and error I have been able to configure Thunderbird to receive emails, but I can send on only one of the email accounts. On account #1 - The inbound email settings are set to a server setting of pop.mail.yahoo.com, Connection Security ssl/tls and authentication Oauth2; the outbound server is smtp.broadband.rogers.com with the user name being the account email; it works fine. On account #2, the inbound settings are the same except for the account email. It works fine. On account #2 the outbound server settings are also smtp.broadband.rogers.com. However if i add the email for the second account to the user name on the outbound settings it then blocks the first. Clearly I am doing something wrong when configuring the outbound server settings but I cannot figure out what to do.

Hi! I want to send mail merge and I have this problem /AppData/Roaming/Thunderbird/Profiles/5mimdst6.default-release/Mail/Local Folders/Unsent Messages?number=6 cannot be found.

Please check the location and try again. What to do? Install ones again?

OK this is complicated. Background is that I use Verizon email, which is now owned by AOL, and using AOL servers. I've used email on this account for *years* and have thousands of emails accumulated. I've always been a user of POP, but am trying to switch to IMAP now (that's a separate story).

I see these instructions for switching from POP to IMAP:

https://support.mozilla.org/en-US/kb/switch-pop-imap-account

Looks great. I tried it and it failed initially, because of password issue (part of the long story I won't go into unless necessary). Now I want to try again, but TB won't let me - it's giving me "incoming server already exists" error. This appears to be a bug in TB, where it "half creates" a server when the initial creation fails - the half-created server doesn't show up in the server list in TB however, so you can't correct it, and it doesn't allow you to create a new one because it conflicts with the half-created one!

I see a mention of deleting your whole profile in the Windows appdata folder:

https://support.mozilla.org/en-US/questions/1283682

But there's no way I want to do that - I have thousands of historical emails there, and don't want to lose them.

I see the server listed in the prefs.js file (text file) as one of the servers. I tried just deleting it there. That doesn't work however - it just gets re-created when I close and re-open TB. Apparently that prefs.js file isn't a source for profiles it's just a file where settings are saved off, and the actual server profiles are in some other file (maybe panacea.dat?).

Any help is appreciated.

Hi All -

I am running a different version of Thunderbird on two different machines. The two machines have identical email addresses added.

Machine 1: OS: Windows 10 Enterprise Edition Thunderbird: 78.8.0 Portable Edition

Machine 2: OS: Manjaro Linux Thunderbird: 78.8.1 (non portable, installed from Manjaro repository)

Problem: On my Windows machine I have a constant RAM issue whereby Thunderbird is eating up 4+ gigs of RAM causing my entire system to meltdown, requiring constant force quits of Thunderbird or, it actually just crashing. I am constantly submitting crash reports through the built-in Thunderbird crash dialog. When I first open Thunderbird in Windows I'm seeing RAM usage of about 290 megs, that slowly creeps up over time, often times peaking at over 4000 megs.

The problem does not happen at all on my Linux machine running the full install of Thunderbird.

Assistance much appreciated. Trying to use Thunderbird across all devices. Unfortunately on my Windows machine I am stuck with portable edition. It's close to unusable in Windows as often times I'll be in the middle of a work email and I'll have "not responding" nightmares whereby Thunderbird is completely unusable for ~30-60 seconds or worse a crash in the middle of writing an important email. Really trying to avoid going back to Outlook on Windows for multiple obvious reasons.

Thanks in advance.

I changed my email password today due to a security issue. After changing it my incoming mail server is fine but my outgoing server won't accept the new password. I tried changing the saved password in the manager and it still won't work. I also tried changing back to my old password and it still won't work. Any Suggestions?

I have a local folder which I no longer require. I have deleted all the files within the folder but I cannot find am option to delete the folder itself. Delete is not included when I right click on it.

When I print an email, all of the HTML data prints out at the beginning of the email. If I try to forward an email Thunderbird includes all of the HTML data as a header for the message. This really makes the message a mess and is very confusing for people. How do I get rid of the HTML data which is supposed to be hidden?

I have been trying to download Thunderbird to replace Outlook Express but to no avail' Is there a problem with the site. If not please advise how to do it. Many thanks David

Since several weeks, I have a bunch of problems with Thunderbird when sending/receiving e-mails. I'm using five accounts (mail adresses) - two Outlook/Hotmail, two Gmail, and another one Proximus-. Once a week there is parameter mix up between the different accounts (server names In/out, SMTP definition, names, authentification method, (password), connexion security (STARTTLS,...). One account got the parameters of another account, users names are mixed up, server names are mixed up, security and authentification parameters are changed, so that it's not possible to send or receive any mail. Even when changing/restoring manually any parameters, it changes those of another account. It's becoming a big mess and it takes me a while to restore this situation, trying to find back the correct parameters at the wright places. The first time I got this case, I had to cancel one user account and re-create it, losing all my messages...A real disaster !!

I'm using Thunderbird for a while and I never experimented this kind of things in the past. Is it linked to the new version update ?  

Can anyone help me ? Thank you very much. March 27, 2021

I use my desktop computer for email. The email was also received on my iPad. I didn't want the limited iPad memory filled with my emails. So I deleted the inbox on my iPad email, not knowing that this would also delete the inbox on my desktop. The deleted emails are not in my trash or deleted bins. This happened a few days ago. Is there a way to recover the inbox on my desktop?

Since the Thunderbird 78 update 3-24/5 depending on clock setting, I can't get my AT&T email through TBird. I tried the troubleshoot fix to go back to the old security setting with no luck. I have not knowingly changed any settings in AT&T or TBird (just the auto-update that occurred a couple days ago). I can get into AT&T via their site. I don't save passwords so there isn't anything to delete. I can send a false pw and get the same response:

Sending of password for user XXXXX@XXXXX did not succeed. Mail server inbound.att.net responded: Server error - Please try again later.

Win 10, TB 78.5 (I think that's the latest), POP mail type I think. I'm not much of tech type I usually have things auto set and default/recommended settings.

I read there have been numerous problems with AT&T by others, for the most part I have not had any problems with AT&T or TBird.

I recently initiated the use of the software for blocking senders, and thought I was performing this correctly, but I have now realized that somewhere I've made and error. Any suggestions would be helpful.

Hello Every time I launch Thunderbird v78.9.0 (64-bit) I get the pop up about making Thunderbird the default. If I click on set as default and then close Thunderbird the same pop up will come up.

If I go to Tools > Options > General > System Integration > Check Now. The E-Mail is un-ticked. If I tick it and click set as default I still get the same problem.

Having issues with Thunderbird email login on my desktop computer. Here’s what happens:

I open Thunderbird, using the icon on my desktop. Typically, this would bring me directly to my email account. Instead, I receive this message:

  Enter your password for rexahall@bellsouth.net on inbound.att.net:

At that point, I enter my email password. While it is attempting to connect, this message shows at the bottom of the Thunderbird screen:

   Host contacted. Sending login information.

After a lengthy wait, I receive this message:

   Sending of password for user rexahall@bellsouth.net did not succeed. Mail server inbound.att.net responded: Server error - Please try again later.

I have been trying again later for several days.

I set up a new account through Yahoo, using my original email ID and password, and loaded the Yahoo App on my tablet. This worked to gain access to email on my tablet.

Do you have suggestions on how to fix this problem?
