Thunderbird ver 140.0 (64-bit) on Windows 11.

Brand new, fresh installation of Thunderbird. - Added a GMail account. That worked. - I tried to add an account with my personal domain. I enter my name, the email account, and Thunderbird gets stuck in an unending loop looking up the configuration. - Other email clients have successfully looked up the config and did the setup without a problem. - The email account is handled via IONOS.com servers. - If you gave me a manual setup option I could handle it but there is none; TB goes straight into trying to handle it itself.

Any ideas?

TY, Frank

I have 3 e-mail accounts and the third one I added is the one I set as default. For some reason the first two show together in the unified folder, but the third is separate on it's own. How do I get all three in the unified folder?

New Laptop. Windows 11. Bitdefender protection. Installed Thunderbird and a first gmail account on new Laptop, all OK. Attempting to instal a second, different gmail account I get the following message from Google:

"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." 

No problem having installing the 2nd gmail account in my internet browser on new laptop after continued failures to instal in Thunderbird. NB I have both gmail accounts previously (and easily) installed and working in Thunderbird on PC, old laptop, phone. Issue does not make sense. Does anyone have a solution please.

Hi, I am trying to use Filelink to send a large file. I selected WebDAV and am trying to log in there on Mozilla's Composition screen. Under Private URL it wants me to enter my username and password. I entered my email address and password but error message says account not properly configured, What am i supposed to do?

Hello all!

According to the article [Firefox Profiles] there is supposed to be a way to manage profiles through the account icon. I do not have that option on my build 140 with windows 11.

I created profiles using the about:profiles command; however, they seem to want to be separate accounts, not profiles.

I want help to achieve the functionality as described in the article so I can stop using Edge because I need to keep my work/personal/school accounts separate.

Thanks!

Hello, I tried following the steps on [https://support.mozilla.org/en-US/kb/.../moving-thunderbird-data-to-a-new-computer]. However, I currently have a flatpak installation where I land in a folder which also has executable among other files (?). I do not see the usually named profile folder and therefore cannot copy it to my new computer. Do you know how I can move in this case? Thanks

I received an email saying that I had to sign in in order to keep my account. I did not click on the link provided since I thought it might be a scam. Was this a valid email? If so, is signing in now meet the requirement to keep my account?

Is there a way to preempt the initial download when connecting an IMAP account initially?

Presuming you plan to make "Keep messages in all folders for this account..." UNchecked, I've found I can only go into settings as soon as possible after connecting the IMAP account to cut off the automatic start of downloads for local email copies. I then search for the email files locally (am configured for maildir) and manually delete.

Not the end of the world, but seems a bit janky. Is there a way you're supposed to be able to set synchronization settings BEFORE Tb starts syncing?

Thanks.

Hi, When installing my Yahoo account in F-bird, I chose the option to keep copies of the messages on the server when downloading them to my local folders. But all my message folders on the yahoo server appear to be empty after I copied them to my local folders. Can this be undone? I'm using other email programs on my mobiles and it's crucial for me that I can access all my folders from mobile and desktop devices. Is there a way to keep them on the yahoo server AND have them synchronized with my local folders? Your help is very much appreciated! Kind regards, Pat

At some stage, one of my Imap Inbox email accounts & its sub-folder have moved to the bottom of the list - under all other folders (Sent/Junk, etc). The Sent sub-folders for this email account are in the correct place. I have tried all solutions that I have found: Subscribing; unchecking only show subscribed; playing with the settings on the webmail server, reinstalling, etc & I still can't get it back to the top, where it's supposed to be. I have attached a screenshot as it was & how it now is (worse) after updating my OS to the latest. Does anybody have a solution for this scenario?

[Latest TB on MacOS Sequoia 15.3.1 (just updated from previous version).]

Problem:

You remove an account like Google from Thunderbird, but Thunderbird continues to repeatedly show a pop-up to log into that account (in my case Google). I've noticed it even freezes the Thunderbird UI on startup.

I have two computers on which I use Thunderbird. I have never been able to successfully copy my email filters from one machine to the other, no matter what method I employ. It seems that this should be at least part and parcel of copying my profile to the new computer, but I find I have to rewrite the filters yet again. Please assist.
