I feel like this has been asked a million times, but yet I cant find a current answer that resolves it from all the posts on google. And some are conflicting.

I added my gmail account. Imap. I dont want it downloading and saving thousands of emails. How do I stop that?

Is the only way to do that, by limiting the sync settings to like 7 days? Is this screenshot, the correct area?

I also tried Unsubscribing all the inboxes, Save, close. Then check the Subscribe pop up again, and it just re-checks them all! I cant uncheck them, it just rechecks them.

Yesterday I upgraded my PC from Windows 10 to 11. Today I discovered my Local Folders are not visible. Searching tells me the messages still exist, but TB does not show the folders. I did the same upgrade a month ago on a laptop (Windows 10 Pro to 11), no problems. I didn't externally back up the messages as I am a dinosaur and don't know how, but at least they are still on the hard drive. Thousands of them though so I need the local folders back. Tried all the fixes I can find on the Community Forum, without success. Can anyone help please? Bob

I use Thunderbird 115.18.0 on a Windows 7 machine. I wish to transfer all my Thunderbird data to a machine running Linux Mint 21.3 which has Thunderbird 128.12.0esr. I have not been successful after many tries. Could this be because the Thunderbird revisions are different? If so, can I get 115.18.0 to install on my Mint machine? If not how should I proceed? I have already tried creating a new .thunderbird directory with ********.default directory from the other machine. I have also tried a new .thunderbird directory with a the ********default-release directory as directed by one site.

My old email server was Mediacom (mchsi.com). I had that email account plus a gmail account on Thunderbird. Sometimes people said their emails to my gmail account would bounce. I changed email servers and no longer have the mchsi.com email or Mediacom server and have 2 gmail accounts on Thunderbird. The new one works fine. When I send an email to the old gmail account it bounces back saying "address not found. Your message wasn't delivered to ------@mchsi.com because the address could not be found or is unable to receive mail. 550 5.1.1 I had the tech that sold me the PC look at the settings on Thunderbird for the gmail account and he said they were okay. Where else can he check? Somehow the pc thinks that just that one gmail account is run through or attached to mchsi.com Kathy foggiak@gmail.com

Hi, Forums - I am a new Thunderbird user based on on-line research suggesting Thunderbird as the best way to relieve gmail account with local mailbox archiving. My gmail is out of storage by end of the month and my plan was to move a bunch of old messages into local Thunderbird mailbox to clear room in the google account. I have set up Thunderbird successfully with gmail using IMAP connectivity option. Thunderbird shows same folder structure as labels in gmail and displays all messages from the oldest to newest. So then I tried the "archiving" by setting up a folder structure under Thunderbird's Local Folders. Specifically, to start with I I set up Inbox_archive and Sent_archive and used right click Move To > Local Folders > Folder name to move old messages from live ...@gmail.com tree to Local Folder tree. Since there is also an option Copy To, my understanding was that Move should be different from Copy by also removing messages from gmail and move them to Local folders. At a first glance these steps seemed to work. I see unique old messages in Thuderbird Local Folders. I don't see these messages in Thunderbird's gmail inbox/sent and I also don't see these messages when I search in on-line gmail in:inbox and in:sent. I noticed, however, that google storage size didn't budge. I moved a thousand of more messages in the same way (thinking maybe older messages were just small) and the storage still didn't decrease. I then looked around in on-line gmail and found the messages that I presumed "archived" still sitting in gmail's All Mail. This explains why the storage size didn't change. I searched on the forum and on-line and can't get a confident answer on what am I missing to actually remove the messages from gmail - ideally in the most straightforward manner in one action as a cut and paste from on-line to local folders. Are there any IMAP/account settings that I should have so that Thunderbird's "Move to" actually removes messages from on-line account? Or is there a different archiving command/strategy I need to use?

I am hesitant to do any more trial and error on my own since I already messed up my gmail by having now thousands of messages still sitting in All Mail without proper Inbox and Sent tags and, thus, would appreciate the recommendation from someone who is familiar with my use case.

Thank you.

Win 11 and Thunderbird 140 not working and I have tried all the things I found on the internet and none of them work. I have tried cleaning my registry and deleted directories and uninstalled thunderbird re-started and it will still not work.

I guess I have to forget thunderbird. It is a shame.

I have lost the indicator in the folder pane showing which folder I'm in. It used to have a small color tab in the folder pane on the left hand side. Indicating that the folder was selected. Any ideas to get it back? Thunderbird 140.3.1esr (64-bit)

I FINALLY was able to find the original profile, all messages in the In Box, plus all folders with their contents. 'Lost' when our ISP's ' tech support person ' had me close/remove the TB POP3 account and create an IMAP account).

I need to merge the new small profile (In Box & with basic folders) into - onto the BIG, original, profile. So each time I get/check mail everything goes to, ends up in, the Thunderbird account containing all the OLD data and new working account.

Please remember I am barely TB literate, so start at 1 (A), not 27 (Z)& no tech words. Nor acronyms please.

Thanks! Remain in GOOD health, be WELL, 'n be

If there's one thing I can count on, it's that the next version of Thunderbird will be more buggy & unstable that the previous version, and v 140 certainly does not disappoint in that category. It crashes & closes multiple times per day. Any time something else may be using a lot of resources, Thunderbird freezes up and if I click on it, the app crashes & closes. At least the previous just stayed greyed out until it was able to complete the task and didn't crash & close. Great job Mozilla.

Went to search for someone in the Quick Search and it did not bring up their emails in the folder, which exist as I confirmed by sorting alphabetically and finding them. Why is this?

Every time I open thunderbird I get a blank screen with this message, 'Edge: Too many requests' over the top of the thunderbird screen. This screen stays on my desktop after I close Thunderbird and I have to change my screen resolution in order to close the screen. Can you help please? Martyn Smith

When I let thunderbird compress the inbox and other folders, the not read flags on all new emails get reset as if I have read all of the new emails. Compressing the inbox and other folders should have no effect on the flags showing a message has not yet been read. That only makes sense. The not read flags getting reset started happening several versions before 145.

Two nights ago I uninstalled ExpressVPN from my system at the instruction of one of their "support" people. My computer immediately lost the ability to access half of the websites I tried to visit and Thunderbird wouldn't send or receive email. I rebooted and that fixed every issue, but since then, Thunderbird no longer checks for new messages for any of my accounts. If I manually instruct it to check, it downloads the messages with no problem. I don't use any add-ons, and I'm using the latest version on a Windows 11 PC. I have already tried deleting global-messages-db.sqlite, repairing each mail folder from within Thunderbird, clearing the cache, and running an install of the latest version. I have also tried changing the setting for each mail folder to alter the interval for message checks by a minute just to see if that would jog it, but no luck. I've looked at various other help threads for this and am out of ideas. Thanks in advance for any help.

Dear helpers,

I want to upgrade the hardware of a friend - and so I moved the homedir of the user to the new system, as I have done every time before in my life. But in this special case Thunderbird will not start with the used profile.

Thunderbird generally starts with e.g. the -P switch. But it will not start the default profile of the user. I tried to go this way concerning the versions 115 -> 128 -> 140 without success. I deleted all lock files, if there were any. I spent a lot of time with e.g. copilot - but it could not help me. I'm at a loss.

Is there any documentation with a kind of step-by-step instructions? Can you give me a hint, please?

Here are the details:

Source: linux mint 20.2 uma Thunderbird 115.18.0esr 11th of december 2024

Destination: linux mint 22.3 zena Thunderbird 140.7.0esr

Thank you in advance for your help.

Something horrible and time-consuming has changed within this past week to Thunderbird. My version is 140.7 1esr 64bit. Over the past 4 days or so, I've found I cannot scroll down and see the full emails--until I have to use this new pop-up system.

This is definitely not an improvement in my estimation. Is there any way to undo this?

I have an existing Tbird account for my Gmail emails. Have set up a new Tbird account for my Outlook email account. Would like to move all emails, including folders and subfolders, to my new Outlook Tbird account (with the intent of closing my Gmail account altogether).

Would appreciate learning the steps to ensure the emails, folders, and subfolders are moved from Tbird Gmail account to Tbird Outlook account
