I've been using TB on 2 of my smaller email accounts for several months and really like the way it operates. I'm nearly ready to add my main email account (web-based Outlook) to TB but have one final question. If I add the account to TB, give it a fair try, and just don't like the results, can I simply delete that account from TB and go back to accessing it via its website? I have confirmed that POP is disabled for my Outlook account so I understand all email remains on the server until I remove it. I also understand TB would leave the email from the account on the same server, again pending some action I might take to remove it. So it would seem that I could delete the account from TB and revert to web-based access for the account, just as I'm doing now, and the folders and saved emails would still be there. Am I overlooking anything?

I have suffered a total hard drive crash. Fortunately, I had a complete disk image saved to iDrive. After many hours, I was able to find my profile in the appdata and watch yesterday as my 10000+emails (approximately 10 years of emails!) streamed into my new PC from my Comcast/Xfinity account. However, when I went to access my TB account this morning only a small percentage of the emails that downloaded yesterday were accessible. My TB email account is essentially the file drawer of my life. I want and need to be able to access all 10000+ on a daily basis. What did I do wrong? How can I fix this. Thank you so much!

When encountering a problem with a new release and wanting to downgrade back to an older (working) version - especially if some plugin I depend on hasn't been updated yet. The current version is well marked, but it would be helpful if the older versions had a subject line like "Release 115.x.x (github commit id)" so we can do better than walk back one release at a time. All flatpak examples for rollback show meaningful subject lines, but Thunderbird and other flatpaks I actually use don't seem to.

I have tried many times to add a third email (Gmail account) to my Thunderbird email application. I successfully added both a Comcast and Outlook email account, but Gmail won't install. I'm using Windows 11 on a Surface Pro 8 laptop.

Hi, I am running Thunderbird v. 115.9.0 on Windows 10 on my desktop. I have been forced by Rogers in Canada to migrate my internet service from their legacy internet service to Rogers Ignite with its Ignite (Comcast) gateway. My email accounts were supposed to be migrated automatically, but, for reasons unknown, were not, and a tech support representative had to migrate them from the old legacy service to Ignite. After that was done, I opened Thunderbird, and was asked to authenticate my 2 Rogers/Yahoo email accounts, one of which is my primary account, the other a secondary account. I was asked to authenticate the secondary account first, which went well. I then clicked on my primary account in the left-hand pane and was again asked to authenticate, but the dialogue box showed it was for the secondary account. Thinking that this secondary account authentication was just being repeated for no particular reason, and not thinking that the email address in the authentication request box could be changed, I clicked Agree. My primary account is now showing the exact same emails as are listed in the secondary account, and I'm extremely concerned that I will not be able to recover all of the thousands of emails in my primary account, many of which are business-related. When I log into my primary account on the Rogers/Yahoo mail website, the emails in the primary account are still showing, so I know they are still on the Rogers IMAP server. However, I really want to continue to use my primary account on Thunderbird. I'm not sure if I should delete the primary account and recreate it - the Rogers support tech said that deleting the account may result in an issue where my current password for a re-created primary account may not be recognized, so I'm leaving things as they are until I hear back. It the advice is to not delete and recreate the account, what steps can I take to recover the emails on my primary account in Thunderbird. Thanks in advance for any help and advice that can be provided. LES.

Hello, I use Thunderbird portable. I imported as Imap an existing account at Infomaniak.com but all the personal folders and subfolders were missing. No problem, just right-click on the account and choose "subscribe" ("s'abonner" in French), ticking all the proposed folders. So in IMAP it works, but if you set the account as Pop3, the "subscribe" function doesn't appear. I need Pop3 for an account to be imported into Thunderbird. How can I do this ?

Thanks for your help !

Hello, I have two email addresses, one personnel, one business. The other night, Thunderbird asked me to download an update. Since downloading the update, all my business emails and subfolders are gone and have been replaced by my personnel email address and subfolders. (in the left hand pane - pic attached) The business emails and subfolders are on my main server yahoo, but are not on my Thunderbird program. Can someone help me to recover the business email address emails and subfolders? Thank you.

Hello all together,

i just reinstalled my whole pc, win10 64. I exported my profile including all possible data, the .zip was too big to import so i copied it into the profile folder, on my desktop, in another foldet etc. But i always get the error message shown in the picture. This is my only chance to have access to my (partly) old email accounts... that's why i followed all steps, but i cannot import everything. I REALLY need your help and would appreciate it A LOT.

Thank you in advance!

I'm looking to migrate from IMAP Rackspace to Microsoft 365. At the moment, we are setup in Thunderbird but since Rackspace can only handle 25GB of emails and most of my users had to archive their emails locally through Thunderbird. Just checking tool that we can use to migrate the exported archive emails from MSF to PST file so it will be compatible with outlook once the migration is complete, or is there a better option rather than converting them.

Sadly, my old Windows 10 PC crashed, and I'm migrating to a new computer. I have a backup of the old default profile folder (9k7faw1z.default), but not of the entire Profiles folder. I have tried to import this old default profile using the import function in my new Thunderbird install on my new Windows 11 computer.

Alas, I get the error message "Import failed unexpectedly; more information may be available in the Error Console." I looked in the error console, and it's empty.

Is there a better way to import my old data from my old default profile folder? It's 3GB of valuable data and I'll be in a pickle if I can't access it.

Thanks very much.

Until the 9th of april I had no problem since then I keep on getting the message: login to server imap.tools.sky.com user namemorgandavid33@sky.com failed

retry or enter new password.

I contacted sky and I did change my password on their advice and I still cannot login. How do I get thunderbird to accept this new password. Or is there another issue with logging in?

The Sky.com email is now provided by Yahoo. I can access my emails there but I prefer Thunderbird and have used it for some time now. Thank you for your help.

I am trying to import mails from Microsoft Outlook 2013 into Mozilla Thunderbird 102.3.2 (64-bit), but I get the error: No Profile found, see the attachment. I have set Microsoft Outlook as my Default mail app in Windows 10, my OS. But it didn't help. H.C. Enevoldsen hc@pushkin.dk

I had a functioning thunderbird, but do to my host provider I had to change some of the configuration (had (owl) suffix). This left 2 profiles. The new profile wouldn't work until I deleted the original. I did a save so I have all the files, now which ones need to be restored. ( a full file backup prior to adding new profile so all org profile files are available)

A profile directory displays all of the folders, 2 files for each folder a MSF and an MBX. Some also have a file type of File.

Which has to be copied, will the folders be created with the copy or do I need to create them in thunderbird first ?

It's not true! Clicking on the close thunderbird button in the error message does nothing, I've uninstalled, reinstalled rebooted. I've had this laptop 3 days, do I need to To go back to factory settings on this laptop.

I want to move Thunderbird local folders to an external drive (Seagate). I am working on a desktop computer with Windows 10. Where are the Thunderbird local folders? The files don't display anywhere in Windows explorer. I am able to transfer all other files such as jpg. and pdf. files from the desk top computer to the external drive by dragging and dropping, but I can't locate the Thunderbird local email files so as to be able to drag and drop.

Since I have problems with version 115 (ImportExportTools NG does not work in this version) I am forced to restore version 102. Unfortunately I can't find a way to download this version anymore. A download possibility for older versions would be very helpful. Thanks a lot

I recently installed version 102 and I am having an issue with password manager. I need to enter my password each time I want to check my email. If I check the box for password manager to save the password, I get the incorrect password error message. If I enter my password but do not check the save password box, I can retrieve my email. If I leave Thunderbird open I can retrieve email without reentering my password. If I exit Thunderbird, restart and retrieve my email, it asks me to enter my password again. I looked in security settings - My saved password box is empty and I can not add any accounts to it. I have tried deleting key3.db, cert8.db, logins.json to no avail. Any ideas?

I am looking for a new email service provider, and Proton mail seems to always be near the top of the list. Searching Thunderbird support yields only help from a year or more ago. How well do proton and Thunderbird mesh currently?
