I always keep program icon in tray and when a new/unread email arrives, a separate yellow icon would pop up next to it... Well, after updating from 158 to 159, that new/unread icon is no longer popping up. Now I have to periodically click the main program icon to open Thunderbird and see that there's tons of new/unread mail sitting there, but that yellow tray icon never showed!

I would like to roll back to 158 but it is proving to be quite difficult.

cannot seem to send emails to multiple people without going thru mail merge. I can no longer type the persons name in to: field and it will not autofill. I tried to go to calendar function and got a blank screen.

Can I go back to a previous version?

Current official docs explains how to backup and move your profile, it assumes you only have one. I have multiple profiles which means about a 20GB backup but I only want to backup one specific profile (<2GB).

The backup is not for recovery but I need to keep a history records for a specific account which can be accessed through Thunderbird even if the original email account no longer exists.

To backup/copy its recommended to do it for this folder %APPDATA%\Thunderbird\Profiles\ (about 20 GB)

While all I need is %APPDATA\Thunderbird\Profiles\xxxxx.default-release\ImapMail\Important_stuff* (2 GB folder and .msf file)

Any better solutions than these?

1. Use a backup method that excludes specific folder and files in backup/copy of
2. Have a completely different installation of Thunderbird that only does the Important_stuff account (Thunderbird portable looks like it might do the job).

I suspect the first version will pick up a lot of unnecessary configuration and other stuff.

I was not able to boot up my Thunderbird email client and had to reload it. But after I got it going, I realized there are many missing folders, and there is a lot of missing messages in my "sent" folder. Why?

I reset my Windows10 computer last week, reinstalled Thunderbird and got it to work as POP3 for about 5 days, but now it won't connect to my e-mail account (@prodigy.net), which I normally access through Yahoo Mail. Then on Wednesday, it just stopped working.

Last week I had to enter a passkey in as the password, but it still needed to be set as a "Normal Password". This week I have tried the same passkey as "Normal Password" which doesn't work. I tried using the passkey but specifying "OAuth2", and it doesn't work. I have tried the "Normal Password" with the password I use to get to the Yahoo Mail account on line, and it doesn't work either.

The message I get is "Authentication error" and "Unable to log in at server. Probably wrong configuaration, username or password." So, I thought I might change the passkey, but now I cannot FIND how to change, remove or create a passkey. Not at Yahoo.com nor at att.com. Can you help me? Thanks, Deb Fisher

This just started yesterday: When I open thunderbird my inbox does not show up unless there is a new unread email in it. Also my previously set display columns and tool bar all have to be reset each time I open Thunderbird.

Since yesterday , Thursday 29th October. Thunderbird has only been displaying the "Inbox" for my account, no emails are visible in it and all of the directories including the deleted emails directory and spam directory are absent. I have Windows 11 installed. I am using the IMAP server for incoming email and have checked that all the settings are correct. My account displays no incoming emails but can send emails. The directories are still absent when running Trouble shooter and the inbox is still empty. In the Account Settings - Server Settings I tested connection to the server and it said secure connection made - this worked for both outgoing and incoming servers. I have tried uninstalling and reinstalling Thunderbird but the issue persists. Although I do not change any settings the full set of directories will occasionally appear along with some emails and then seconds later disappear again. My email account is working fine on my phone and tablet using gmail.

Over the last couple of days the general appearance / layout of Thunderbird has changed for me. I have attached a screenshot of how it appears now, previously under the 2 talktalk e-mail addresses I had a number of additional folders I also, under SPAM, had spam folders for each e-mail address, in fact I had 2 for each of the talktalk addresses.

I first noticed the changes yesterday but after shutting Thunderbird down I got most of the old layout back, but today I see only what is in the image.

Is this some sort of an update or has my installation been corrupted in some way.

My Thunderbird installation (159.0/Windows11) has evidently just updated, and my Calendar tab is suddenly a complete blank space. There's a support article here that appears to discuss exactly this situation, and gives precise steps for getting into "Config Editor" in Advanced Settings, entering a long search string, and issuing a Reset command. (Mail and contacts are just fine.)

Which I tried...

But there is no "Config Editor" button in the dialog I get when clicking Advanced Settings at the bottom of the Settings tab, only a mostly blank screen with no list of settings and a dialog box in which one can enter text (with options for "Boolean", "Number" and "String"). And entering the search string given in the support article produces, with a bit of finagling, a toggle that will change its setting from True to False and back again (and a trash-bin icon that offers to delete it), but neither "True" nor "False" produces any instance of a "Lightning" extension in my list of extensions (which is short and uncomplicated), so (a) I can't delete the extension as instructed, because it's not there, and (b) restarting Thunderbird only continues to give me the unhelpfully blank Calendar tab. (And I do mean "blank" here - there isn't even an empty calendar grid on that tab at this point.)

I *think* the article is probably right that my data is still there (I can see .ics files with current dates in File Explorer), but at this point I can't get at it and can't seem to get the interface unstuck.

I used to have a corporate Gmail account but a colleague has taken it over and changed the password I removed it from my thunderbird win10 app by selecting it and deleting it in the normal way and all the folders have gone But every time I launch the app on my pc it asks me for a password for the deleted account, then launches a chrome browser page and asks me to log in to my colleague's Google account I've tried deleting thunderbird and reinstalling but this still happens, as though the account details including the deleted one are still stored somewhere on the PC. I have 4 personal email accounts and I use the unified folder facility Can you help?

I have 5 accounts. Since the update when I start Thunderbird, some accounts appear in name only with no folders. Then, if I exit then enter again the tabs may appear and the Thunderbird sets about resyncing them all. Help please.

I send an email and I get this response as a failed send. Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-a2p-646964.sys.comcast.net ESMTP server not available (396356/173.46.82.217).

I'm not receiving any emails in my Thunderbird inbox, though I'm able to send messages (but they're not being saved to my sent folder). Connection to my server keeps timing out. Also it looks like I accidentally deleted all the messages in my inbox -- no messages are currently showing when I open the inbox. I think I did this by "repairing" the inbox folder.

My local Thunderbird program (159.0 (64-bit) on Windows 11) is set to auto-install updates. Upon the update completing earlier today, the inbox and other folders were completely empty. They remain so following a program & computer restart, and also opening the program in troubleshooting mode. I have checked the following: - logging into the online mailbox directly works, and shows all emails - sending a new incoming email to the email address does have the email show up in the remote mailbox but not the local mailbox - sending a new outgoing email from Thunderbird does appear in the local Sent folder, as well as on the receiving email account - the local Thunderbird instance is still able to connect to the IMAP Mail Server (mail.talktalk.net) - the following settings are configured, and I believe haven't changed since prior to the update:

 - Check for new messages at startup is **enabled**
 - Check for new messages every 10 minutes is **enabled**
 - Clean up (Expunge) Inbox on Exit is **disabled**
 - Synchronization & Storage: Keep messages in all folders for this account on this computer is **enabled**
 - Synchronize all messages locally regardless of age is **enabled**

I have ~100gb of space available on my hard drive

I'm not sure what other settings might be helpful. Please let me know if there's anything else I should add.

My issue has two parts. The first is that I want new emails to appear in my local email client upon arriving, as they did previously. The second is that I want to have the full set of emails on my remote account available locally, which is currently no longer the case. There is also no sync activity happening, and apart from establishing the initial connection to the mail server I can't see any activity in the bottom left corner.

Whenever I start my PC, the first time I click on the Thunderbird icon at the bottom of my screen (is that still called the taskbar?) I have to click on it a 2nd time to get it to open. After that I only have to click on it once. Does anyone know I can get it so I only have to click on it once the first time as well as understand what may be causing this problem?
