Thunderbird Support Forum

When I selected the TB icon a window came up saying I must set up my existing email account. I fill in my name, my eddress and password. The next window that comes up shows TB found mobile.charter.net but my email was set up using email.twc.com. The port numbers are the same but the server names are different. When I complete this activity the end result is that my information if rejected. I attempted to configure it by hand but it too was rejected. I am using an HP desktop with the latest Win 10 OS. I don't know what to do.

Thunderbird’s connection to one of my gmail accounts failed today.

I removed the account and then tried to add it again to Thunderbird.

When logging in using a Google generated App password, I receive the following message:

"400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

OAuth2 is in place, and I’ve carried out all other recommended checks I can find on your website. My other Gmail accounts are working fine.

Please can you help? Many thanks.

I am going around in circles here. I have searched and all the options I have found appear to be out of date or don't work. All I want to do is increase the size of the fonts I see in the left hand folders list and the folders message lists in the main panel. It's far too small for me and everything I have tried makes no difference. Please guide me.

I desperately (sobbing here) need someone to hold my hand and walk me through this!!! I uninstalled the newest version (115) and installed the previous version (102) because of an outgoing mail problem. It gave me a warning that the newer version changed my profiles and it's not compatible so I downloaded the new version again. The import screen doesn't look anything like what it says in the help files. I don't have an option for importing from a previous version.

Please rescue me. I run a nonprofit and I have deadlines and meetings next week that I was supposed to make arrangements for and I've been dealing with this for almost a week.

Hi,

TB 91.5.0 on Windows 10 (with profile folder excluded from virus scan)

The latest update to seems to have resurrected a problem with saving copies of sent emails. Sending works fine, but copying of the sent email to the sent folder causes the send dialog to hang. Disabling the "Place a copy in:" option in account settings eliminates the problem. Using the "Other" option to place it in a local folder works *that is not part of a unified folder* works OK.

I have tried repairing folders and deleting the sent files inside "smart folders" in the profile, with no luck.

In a world where respondent's often draft messages about a new subject by lazily replying to messages on an old subject, does anyone find Threading helpful? Why is it now the default.

After View/Sort by/Unthreaded then propagating that by "apply current view to all folders." All folders do in fact sort by unthreaded. But if I create a new subfolder it defaults to sort by threaded. Please, is there anyway to entirely disable Threading?

My friend has been using Thunderbird for a long time. Recently I installed her new PC and restored her account profile using the profile folder on her old PC. So far so good. The problem is that her mails are not organized in folders on the mail server but she has a whole collection of folders in her Thunderbird mail client and is concerned about loosing her mails if the new PC (or the disk) would crash at some point. Of course she could just re-install Thunderbird after fixing the crash problem and sync with the mail server, but then the folder structure would be lost. First I considered using a back-up program to keep a back-up of her Thunderbird profile using cloud storage. My second thought (should have been my first thought...) is that she already has a back-up, namely the mail server. The ISP does a better job than any local back-up program to keep her mails safe. Only the missing folder structure remains a concern. So here is the question: if I change the setting to sync all folders with the mail server, what will happen: 1 - the folders in Thunderbird will disappear (only the folders, not the mails) because there are no folders on the mail server 2 - the folder structure from Thunderbird will be mirrorred on the ISP's mail server. Which one is it?

I changed my incoming to OAuth2 and I was able to receive messages in Thunderbird from my AOL (Verizon) account but I cannot send messages. It asks me for password, when I enter password it states "Login to server smtp.verizon.net with username [email edited] @verizon.net failed." There is no OAuth2 for outgoing

Please help thank you

Yesterday I tried the 115 (Supernova) and I was disappointed because of the toolbar on top of the TB window: I think that you should let the user choose where put any toolbar, and I didn't find the way to move in its "classical" place (not at top but below the menu). There is a way to do it? And if not, please consider to give it as soon as possible.

For no apparent reason and all of a sudden I cannot download email. I can still send email. I tried all the suggested remedies and checked all my settings. Running 91.5.1/Win10Pro I can download my mail on my phone and tablet as well as using the web based access on my PC. I tried disabling both my AV, and Defender. No clue where to go from here. Any guidance will be very much appreciated. Thanks!!

On 30 May, you may lose access to apps that are using less secure sign-in technology

To help keep your account secure, Google will no longer support the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password. Instead, you’ll need to sign in using Sign in with Google

I moved to a new PC and installed 64-bit Thunderbird (had 32-bit on old PC). I restored my profile folder from backup and Inbox shows my email and settings look okay. But if I try to reply to a message, TB freezes. It opens the new message dialog, but the TO is left empty and everything is unresponsive with spinning icon. All I can do is close the program.

My thunderbird works okay, but when I select emails from imbox folder to delete it takes too long. I researched to find the problem and the only option I found was to add an exclusion to the profile folder on my windows security antivirus. Now I can select emails from the imbox and delete them without a problem, but my concern is if I will be vulnerable to virus.

How do I change "POP" server to IMAP server? Verizon default to AOL requires an IMAP address. Putting new IMAP address in doesn't work unless the server type is changed. You can't delete it and change it in "server" settings. This 77 yr old needs more guidance please.

Outgoing SMPT doesn't need a change. Thank you.

I'm migrating to a new computer and from Windows 10 to W11. I have successfully exported/imported the contacts using the export tool, but cannot figure out how to ex/im the calendar. I am using a SanDisk drive to move the files. Both systems have TBird 102.1.2 (64-bit).

Please give step-by-step instructions to do the calendar (only) ex/im. I do not use the Mail feature.

My mom's version of Thunderbird is crashing a lot on exit. She's running the latest version of Linux Mint as OS. What is going on with this crash and how can we prevent it?

I think at some point I was able to send a private message. Or maybe it was just a reply to a private message that was sent to me. I remember something about clicking on a person's picture.

Thanks is advance for yoiur help. SweetTasha

I have been using Thunderbird for many years. And, I've created multiple Folders (with multiple levels drilling down) which I place emails that I want to save. A couple of days ago, I left clicked holding an upper level folder, and dragged it to another folder. When I did that, Thunderbird showed a little circulating icon spinning until the process finished about a minute later. At the end of the process, a whole group of folders and emails disappeared.

When I explore the profile, under the folder "Mail", "pop.gmail.com", "_Companies.sbd", I can see folder names that correspond to the folders that disappeared. In those folders, I see files with the file extension "wdseml". Some folders don't have anything in them though.

My questions are:

(1) Can folders that disappeared be recovered where I can access them again in Thunderbird? And if so, how do I accomplish that? Is there an index file somewhere that can be audited and adjusted?

(2) If there is no easy way to recover those lost folders and emails, can I just remove the existing profile and replace it with a backed up profile I saved about one month ago. I would lose all the emails I had from that point to now. But, I would have all the original folders and emails up to that point.

Thank you for and help, direction or advice you can afford me, Chris

After updating Thunderbird to the new version 91.9.1, most of my email messages disappeared.

An error message was displayed after updating to the new version. Thunderbird restart chashed and I started the program again, just to noticed that the messages were not anymore in the folders.

How can I recover my messages?

Hello,

This morning when I opened Thunderbird it wouldn't accept my master/primary password. I've used the same one for years, so I know I've not forgotten it. Plus it worked yesterday!

Only thing that seems to have changed is the update to Thunderbird 91.

Any tips would be greatly appreciated.
