I have several errors associated with the unified folders display. I have 6 email addresses coming in to Thunderbird. 3 are IMAP and 3 are POP. I have the POP addresses consolidated into the "Local" Folders Inbox, Sent, Trash etc. In the "All Folder" account views, the Local folder correctly displays one Inbox, one Sent, one Trash etc. The 3 POP emails accounts are being consolidated appropriately. However,in Unified folders, the Local folder as well as all of the individual POP addresses are now listed for the Inbox, Trash and Junk folders. There is now no consolidation.

Also, the Unified folders themselves are extremely slow in working. Accessing the properties for the Unified Inbox, Trash or Junk folders results in a long wait with Thunderbird entering a not responding state. Right click operations on the unified folders do not work at all. I cannot select properties, I cannot mark as read, empty or otherwise manipulate the folder. I must go to the individual accounts to manage any folder content. Which I would think makes the whole concept of Unified folders moot.

I am not at all certain what may be the root cause of this rather longstanding problem. I have deleted the smartfolders directory, have deleted the virtualfolders.dat and foldercache.json and foldertree.json files. Nothing seems to work.

Any suggestions?

Hi all, I am using 5 email ids on my Thunderbird installed on Macbook air camped in UAE (Dubai). Recently (since last 3 months), One of my email ids has stopped receiving or sending email. It starts sending / receiving emails, if I activate any VPN. The other 4 accounts work fine with or without VPN. If I travel out of UAE, this problem account starts working without need for activating VPN. Have checked all account settings and compared with the other accounts, no errors from my side. What am I missing? Thanks for your reply,

I run Thunderbird, Thunderbird ESR, K-9 or Thunderbird. Windows 7, 10 and 11, Linux and Android 5.1 and 12.

My desktops all have a gmail and yahoo.co.uk email addresses. Each account is linked to there respective contacts server but all my contacts are in one gmail account which has lost most of the contacts in recent months, that is, only the contacts that I have used recently are still present. So I have been investigating the settings and adjusting in some cases.

Some instances all the account are still linked to the contacts servers. Other cases only some of the accounts are still linked and I want to re-establish the other accounts that have become local accounts, these still have my full complete address book.

Lastly between K9, thunderbird, contacts google I don't know what went wrong but I like advice on how to avoid the problem in future. In the meantime seasons greatings, no hurry my christmas messages will have to wait.

Basically the title. With TB closed when there were no tabs open, I have located the profiles on the win10 PC in c:\users\[user]\AppData\Roaming\Thunderbird and copied said folder onto a USB stick, then pasted it from the USB stick into the same location on the target (win11) PC (and apparently according to the progress panel everything was pasted as it should). On the target PC, Thunderbird does open, but in the default account definition tab (and creates a default-esr profile along the way), but does not find the profiles I copied onto the target PC. I really need the existing mails and folder structure. Thanks in advance!

Hi,

I have my messages in IMAP folders stored in maildir format. I know how to make that happen.

I cannot find a way to have messages in local folders stored in maildir format.

Is there a way?

I have Thunderbird 115.15.0 on win 10 dell xps desktop and want to install Thunderbird on my new win 11 Dell xps. The microsoft store gave me ver 128.5.2. I read that if I use the same version I can transfer my profile from the old computer. How should I approach this? Should I figure out how to update the win 10 machine to 128.5.2 before transferring the profile?

I deleted an email address and it does not show in gmail on the web, but every time I open Thunderbird I get a window saying that the deleted email account is requesting my username and password. How can I stop this? get a window with the message

I setup my account it worked well, I changed my office365 password. I was prompted to login with Oauth2, and it worked. However, I can receive emails, but cannot send emails. I get a notice that my password is wrong when I come to send emails. It just happens because of the password change. No matter what I do I cannot find where the Oauth was saved for smtp. There seems to be a desync, where the password updated for the Incoming server, but never lets me or updates the Oauth for the smtp server. Any thoughts?

Deleting saved passwords, just gets me to do Oauth2 for the incoming, it never takes effect on the smtp server.

Got a new my-own-build desktop and have been doing a lot of set up. Found out Outlook limited me to 10 email accounts (odd since I had more than 10 on the old machine) and so A.I. said "use Thunderbird", which I did use regularly in the 2000-early 2010s. I am setting up (adding accounts) to Thunderbird but one of the gmail accounts gave me problems--Google was causing the problem, not Thunderbird--in setup/authentication and now this account wont add to the desktop for some reason. So I went to my mobile and added the account and am now trying to export that account (through PhoneLink) to the desktop, but the desktop "Import" feature does not have a setting import the file from the phone into the desktop. File has a name 'thunderbird_settings_export_2024-12-21.k9s' and not a 'zip' file or any other thing the Import feature looks at.

I'm trying to put TB on a new computer. I can receive email on the new computer, but I can't send. It keeps asking me for a new password. I enter the password and tell it to remember it, but it just keeps asking for the new password. I'm practically certain that I'm entering the right PW.

What can I do to fix this.

Using thunderbird to connect to the mail server outlook.office365.com with imap gives the message "user is authenticated but not connected" . I have 2 accounts on this server and one works fine and the other gives this message. This occurs on both Windows 10 and Windows 11. Latest version of Thunderbird is being used. Any help would be appreciated.

I would like to be able to click the little fire icon on an email in my "list of emails" window to Mark as Spam, then have Thunderbird automatically move it to my Bulk folder after that.

I looked to see if I could set up a filter to do that, but don't see "Marked as Spam" as one of the selection criteria.

Is there a setting to accomplish what I'm looking for?

Many times when I am forwarding emails or copying and pasting text from an outside source, the spell check will choose a word like "isn't" and highlight "isn" as a misspelled word. This has happened with a number of different contractions.

Additionally, it will pick parts of an abbreviated name in someone's email address in the To: field as a mistake. I do not have the time or desire to constantly, go through a long email and choose 'add to dictionary' or click ignore. Why is it even looking at parts of a contraction, and it should be ignoring the To field altogether.

Is there something wrong with my version or is this how it operates? My TBird is up-to-date: 128.5.2esr (64-bit).

I've tried Troubleshooting Mode but it only recommends "Clear Startup Cache" and when I click it to reboot the program Thunderbird stills fails to load the Inbox file and Troubleshooting Mode again recommends the same "Clear Startup Cache" as a remedy. Not sure what to do to get Inbox file loaded in program. BTW the program does download new emails to the Inbox file but program is unable to load the file. During Thunderbird program restart the message at the bottom left of Thunderbird window is "Summarizing files for Inbox" which after 20 minutes program crashes ans asks for a reboot. Any corrective action recommendations is appreciated.

Thanks, Mike

I am having a problem syncing my Thunderbird folders with iCloud. Every time I have to explicitly check that I want to subscribe to all IMAP folders in my iCloud account. Then after a short while a lot of folders get unsubscribed and I have to subscribe them again. I have experienced this instability with both Thunderbird and Betterbird as well as on Windows 10 and Pop_OS! 22.04. More people have reported the same issue, but no solutions have been shared:

• https://support.mozilla.org/en-US/questions/1444029

Does anyone know how can I fix this?

When I've written a new email and click File > Send Later, will the email be sent automatically and when will it be sent, or do I need to send it manually and how does it work?
