Thunderbird Community Forum

I use Thunderbird on Mac OS 10.14 (Mojave), server is Orange. My account on Orange was referred as POP. I recently transformed it into IMAP ant it works OK. On the IMAP account, I created the same e-mail address than on the POP account, and I wish to keep it.

Now, can I suppress the POP account without loosing my address ? In the Thunderbird help, it is said that : if I suppress the POP account, I will simultaneously loose my address. But it is the same as on the new IMAP ! What should I do ?

Thanks for any help (in French, or in English).

This is an annoyance rather than an issue.

I run Thunderbird as my email and I archive old mail to local folders, which I want to sync to Dropbox.

This works fine, and I have a suitable set of .MSF files (over 100, 000) synced to Dropbox.

BUT. Every now and then (not sure how often, I see dropbox is syncing ALL my thunderbird files, even if they have not been changed.

Can anyone explain how Dropbox determines when to sync?

Is it possible that for some reason Thunderbird does something to the files (for no apparent reason)?

I have also asked the Dropbox forum what is the trigger for a file to be updated in Dropbox.

Thanks, Paul

Starting this week, an increasing percentage of, BUT NOT ALL, incoming e-mails are coming through unformatted, which makes them almost unreadable. In the Cards pane nothing appears except the time stamp. Some examples: id CD/0A-06843-A1BCB986; Tue, 12 Aug 2025 23:15:38 id 09/00-49518-8A0AC986; Wed, 13 Aug 2025 10:26:48 id 24/87-15587-133DD986; Thu, 14 Aug 2025 08:14:41 id 05/94-10997-4184E986; Thu, 14 Aug 2025 16:33:24 I'm running ver. 140.1.1esr (64-bit).

The same messages appear fine in Thunderbird for Android on my phone. Anybody have any clue as to what's going on?

I've been trying to add yahoo account for several weeks, I type in the email address on the add account function and then I just get a wheel of death and have to force shut the programme, I'm on windows 11.

I am using Thunderbird and Firefox. Each are set as default on my MacBook. However, Thunderbird has recently started opening links in Safari instead of opening them in a new Firefox tab like it did just a couple of weeks ago. I cannot figure out how to make that stop. I've verified that Firefox is set as the default browser in my Mac's system settings. What caused this to change recently and how can I make it go back?

I have a dual boot laptop. It came with Win 11 installed and I added a new ssd with an old Win 10 system, which had Thunderbird configured. The win 10 system worked fine with outlook and I saw and verified the password. I upgraded the Win 10 to Win 11 and it all continued to work fine. I again checked the password stored in Thunderbird. When I tried to set up the same account in Thunderbird on the "as installed" Win 11, it fails to pass authentication. I have no idea why since I have checked the password in the "old" system and used it in the new. I have tried using the menu option "New Account" and the submenu option for "+ New Account" within the "Account Settings" menu item. Both seem to take me to the same automatic process - which is what is failing. I can't see what, if anything, I'm doing wrong. Any help much appreciated. The laptop is a MSI Katana AI B8VE (using AMD Ryzen 7 8845HS.

Have been running classic Outlook email in Win 10 for years, with a blueyonder.co.uk (Virgin) email address. Now moving to a new PC running Windows 11. Tried to setup Outlook email in Win 11, but Outlook keeps telling me that my blueyonder address doesn't exist though I still get emails on my phone and my old PC running Windows 10. Given up on Outlook and advised by a friend to try Thunderbird. Now trying to setup Thunderbird. It looks very hopeful; it found my Virgin account and setup corresponding server settings, but when I click on "Done" I get the message "Unable to log in at server. Probably wrong configuration, username or password." I have checked my password by signing in to Virgin, where I can see my emails. Dave.

Thunderbird can't seem to add my outlook account and keeps telling me to check username and password; both of which are correct.

I have two separate accounts; a hotmail account and an outlook account. It added the hotmail, but won't add the outlook account.

There still does not seem to be any way to search for an exact term. For example, if I search for "provider", I get matches for things like "provide", "provides", etc. This makes Search anywhere from unhelpful to completely useless: imagine trying to find emails that mention your friend "Don".

I am sure the people behind Thunderbird think that this "feature" is helpful, and occasionally it is, but it is disastrous when the user knows precisely what they want but can't find it.

Please can we have an option for exact matches only?

BTW, from I can tell people have been asking for this for at least five years.

Hi, I used Thunderbird on a portable computer in installing automatically my mailboxes without issue. Then the systems suggested me to upgrade to Windows 11. I did.

But since that time I can not more use Thunderbird because it cannot set up my mailboxes on outlook and a specific national operator.

Is there an issiue in usign Thunderbord under Windows 11 ?

Tks.

I am trying to re-set my login. I have the correct pwrd . When Thunderbird finds my account and I click on "done" , the message "incoming servicr already exists". After that nothing happens.

Running TB 128.14.0esr on Linux Mint MATE. In the Create new message (Write) window, I want to change the background colour of the panel that contains From, To, and Subject. This is currently a light grey. What userChrome code can I use to change the colour? Thanks

I have tried changing the font sizes in settings, but that doesn't seem to do anything to the font/size used to display the list of accounts and folders. I also tried changing Windows font size, and that does change the font size, but the bottom of each item is still truncated. I can't find a density setting in Thunderbird.

Thanks for any suggestions KR

I've searched and tried all suggested solutions but nothing is stopping the constant popup asking for a password for a long deleted email account. I removed all saved PWs. I removed contacts that received email from that deleted account, I've cleared cache etc etc etc.

Nothing is stopping this extremely annoying popup.

Help please.

Thunderbird suddenly fails to download any emails on one account after a certain date and time but downloads the last email prior to then repeatedly. This occurs on only one of my computers running windows 11 and started immediately following a windows update. Other email accounts from the same email provider continue to work properly.

Trying to set up a new email account in Thunderbird I go to the Account Hub, enter the name and then the email address of the new account and select <Continue>. There then appears a greyed-out box showing "looking up configuration" with the usual turning circle indicating waiting for a response. After three hours still greyed-out with the turning circle and no response. I have tried several times. Please advise a solution
