I'm in the process of cleaning up Thunderbird e-mail before moving to a new computer. I started with 11,593 e-mails in my Inbox and 7,799 e-mails in my Sent folder. I'm now down to 7,634 in my Inbox and 4,965 in my Sent folder. I've allocated 2 weeks for this process and found that it's taking me about 3 hours per day to meet my daily goals. I'm finding that I'm spending at LEAST half the time responding to "Empty-Trash/Compact-folders" requests. There are times I can delete 50 e-mails at a time without getting a request. Other times I will try to delete ten e-mails and get the request. With the old version of Thunderbird I could literally delete hundreds of e-mails at a time. Can you help? Russ Bukwa Yardley, PA ps. I have intentionally given you specific numbers. Based on my software- and test-engineering experience, I speculate you need to create a stress test to solve this nagging problem.

I am having a problem with receiving emails that are someone replying to an email I sent. I don't hear back from them and when I give them a call to see why they haven't responded they say, yes they have. So I go and type their name in the search bar at the very top and it shows me their responses and says that the email is in my inbox but it isn't! How do I figure out where these emails actually are and how can I get it to stop doing this?

Three weeks ago I attempted to migrate my TB profiles from a 2014 mini-mac to a 2024 mini-mac. I thought I did a better job of backing up my profile using CCC than I actually did. In the migration to the new Mac I lost all my subfolders from the last 20 years. Apple created a new Profile and 2 restoration Profiles on the new Sequoia based mini-mac. I wasn't familiar with these and panicked. I copied those files, took them back to the original mac and tried to follow Toad-Hall's method of restoring the subfolders recommended to bmack1 on 23/11/22. However, I failed to carry out the step of going up two levels in the path of the Library to copy the entire "Thunderbird" file and only copied the Largest restoration file. This in turn, "contaminated" the 2014 original Thunderbird mail profile and only an Inbox and Trash subfolder remained. Today, after 3 weeks of searching and reading the generous contributions of this community, I came across a post explaining that the "sbd files" will show the subfolder headings I created in the original sought after Profile. And I found it!!! My problem is I have re-read Toad-Hall's method of re-installing the original Profile and tried to carry that out to the letter by placing the old Profile within a Thunderbird folder and switching it with the current one. But it's still listed as the "Restoration qqg...file" and probably shouldn't be, but I don't want to go any further and risk losing it because I feel I almost have it. So any guidance would be greatly appreciated. Thank You.

Hello, I'm using the most recent version of Thunderbird on a desktop using Windows 11. Just this morning (Aug 11), all incoming email to all my four accounts are coming in with no subject or correspondents showing and when opened the email is not formatted in HTML, just plain text and lots of code. I have tried several fixes with no success: repair folders, turn off all add-ons and anti-virus protection, uninstalled and reinstalled software. Can you help, please? Thanks!

I have a new laptop and did a backup of my files on the older laptop (Windows Home) and restored them to the new laptop (Windows Pro). Then I installed Thunderbird on the new laptop and I already had e-mails on it. But there are thousands of e-mails in the wrong folders.

The Windows Home has Thunderbird 128.10.oesr (32 bit) and the Windows Pro laptop has Thunderbird 128.9.2esr (64 bit). What should I do? Should I uninstall Thunderbird on the new laptop? Then what?

I need to do something with a profile folder, right? But what?

Please help.

It's a mess right now.

I can no longer send messages through the email client on one of my accounts using Thunderbird, which no longer recognizes my internet service provider's password (but it does receive messages). Everything works fine with my other accounts.

Thank you for your help.

why just today is all my incoming emails coming to trasha nd not my in box in Thunderbird worked fine in the morning but i am not getting any mail in my in box it is all going to trash

The global search in TB is completely defective. I am now running 128.2.0esr and hoped that update might fix it. It hasn't. I just wonder, are there any older or non ESR versions I can downgrade/move to, where the search is fully functional?

Is it possible to open incoming mails in the same window as the list of e-mails, just like in Google? I get distracted from seeing suddenly my e-mail in another window/tab.

Thank you!!

Starting on 10/01/2024 Thunderbird no longer allows me to send or receive email.

When I try to read messages using Thunderbird, I get the following: Sending of password for user XX@msn.com did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password.

When I try to send messages using Thunderbird, I get the following: Enter your password for XX on smtp.office365.com:

I have tried redoing the password and it does not help.

This is on a WIN/10 system. I updated to the latest version of Thunderbird and it did not help.

I checked out Thunderbird on my WIN/XP and get the same results as with WIN/10.

When I use Firefox and login to https://outlook.live.com/mail/0/, I can send and receive email as before. The same is also true with my Mobile Phone.

My thanks again to sfhowes, Rick and others for assisting me to get back my ability to once again send e-mails from Thunderbird. Now for the next step.

Just days ago, I migrated my years of Thunderbird e-mails on a POP protocol to IMAP. Before doing so and before also uninstalling my old Thunderbird because of e-mail sending problems and then reinstalling a new version, I saved a profile. Now with the most current version of Thunderbird, I lost (i)a decades worth of saved inbox e-mails (but for the last 2 years), (ii)I lost all of my sent e-mails but a few odd ones, (iii)I lost my archived e-mails in Local Folders and (iv) I lost all of my contacts and saved group e-mail address lists.

My profile is saved on an external hard drive. Obviously the new installed version of Thunderbird must have somehow found the last 2 years of my inbox e-mails but nothing beyond that as mentioned above. Can you share please a recommended procedure where I can better import what I assume I saved correct on the profile I saved twice (I saved a master folder named Profile and separately saved 4 folders - 2 folders ending in default and 2 ending in default-release. Thank you.

When I reinstalled Thunderbird, I got my account back, but the Local Folders were missing. I found where they're hiding on my computer, but I can't figure out how/where to copy and paste that folder so they show up in Thunderbird. Can someone walk me through those last steps, please?

Thanks

Hi all,

After thoroughly searching this database, I could not locate an answer to the issue I am facing, although there seem to have been several similar cases.

My former university has recently decided to delete alumni email accounts, so I am using Thunderbird for email transferring from university to GMail (added both accounts to Thunderbird and then began copying emails and folders). Transfer is slow, depending on the server capabilities etc., but I am going folder by folder and so far it has been fine. I began the transfers a week ago.

Last night I noticed my Thunderbird inbox for my school is not showing anymore. The profile folder is only showing one file (.msf) for Inbox, instead of what should be, in my understanding, two files.

Thunderbird is still communicating well with the university email server because I made a folder rearrangement on the university webmail service (outlook.com) and it showed on Thunderbird. In addition, all my Inbox emails appear fine on the university webmail service (outlook.com).

Any ideas? This is obviously important and urgent.

Thank you in advance.

I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.

I can't seem to get Thunderbird on Linux Mint to work. Everything font related is a mess. I don't know what default Thunderbird uses when it doesn't know a font but the setting is unreadable. I've messed with a ton of font settings but nothing seems to change anything. Note if I copy the garbage and paste it into a notepad, it is totally readable but there appears to be no way to change this default in Thunderbird. Please help.

I made a folder and called it April. One day the folder just disappeared. No one seems to help me recover the folder and i need it. Once I moved emails into that folder they are no longer available in my inbox. SO if you know how to recover my folder help, or if you know how to recover emails that were sent to a folder, that would work also. I use Windows 11 and I have the most recent release of Thunderbird. I use Charter.net as my isp which is pop. Thanks,Charles

I was forced to erase my PC because it was infected with malware. I saved my Tbird profile to my HDD before erasing. I pasted the saved profile to %Appdata% >Thunderbird, copying 1,777 items. When I brought up Tbird, I got the Account Setup window, so I don't think the profile was actually there. What did I do wrong?

Thunderbird causes my machine to 'hang' from time to time,

1. often for up to a second and usually a number of times in quick succession on each ocasion. Sometimes this happens frequently - say every 5 or 10 minutes - sometimes only after an hour or more since the past occurrance.

2. My machine hangs completely - nothing will work, mouse, keyboard, sound, other apps etc. If I happen to be typing (into any app - including Thunderbird - when this happens, input ceases, the cursor freezes and - if the problem persists for a second or two, Windows reports "[app] is not responding"

3. I cannot be certain, but I believe the problem occurs whilst messages are being retrieved.

This is a very serious problem as it means that I can never leave TB running as the problems it causes are not acceptable.

4. This means I cannot deal with incoming messages without periodically re-starting TB - which is an utter PIA.

I am running Win 11 Professional on a 2-year old machine with 64 Gb of memory. I have run TB in Troubleshoot mode, I have confirmed that the problem occurs regardless or whatever other apps are running (or none) and I have proven conclusively that no other app causes any kind of similar problem.

Looking forward yto hearing if others have had the same issue and what can be done about it.

I exported my profile to an external drive, then reset my Windows 11 PC. The resulting file is a zip file. When I import, the import starts, then stalls and gives an error. The error log is incomprehensible to me. How can I not lose my local folders and messages? I tried unzipping and importing that folder, but another error. I need help! Ideas? Thanks.

I've been using Thunderbird for years but suddenly as of yesterday it's stopped receiving messages. First it told me my password was incorrect. Ever since then when I try to click "Get Messages," it simply has no response at all. Nothing happens. I went into my Thunderbird password settings, and upon seeing that the incoming-message password had for some reason reverted to an old, obsolete password, I corrected it and saved the correct one. I've checked several times and the passwords are correctly saved now. But this did not fix the problem. When I click "Get Messages," nothing happens. My Thunderbird is connected to my Earthlink account, which is working fine. When I go into Earthlink, I am able to send and receive messages as normal. So the problem is not with Earthlink but with Thunderbird.
