I need assistance to setup my accounts correctly in my unified inbox. A few times I have lost some messages, when sending mail, they go out from both accounts Is there a way to chat with someone, and to share screenshots. I look forward to hear.

My Thunderbird v.139.0.1 crashed. It would not run at all. I downloaded Thunderbird and it was v.139.0.2. It looks entirely different and created a new profile. I edited the Profiles.ini and replaced the new profile with the old profile. (this worked 2 months ago when I bought a new computer). Now having done the editing to get all my old emails etc, it will not bring up the old profile. How do I get my old profile and the setup from the 139.0.1 look and feel. Thanks.....

Move Thunderbird data to a new computer

I have the complete Thunderbird folder with 15 years of POP mail.

Install Thunderbird on new PC and overwrite the complete folder?

will be the same version of thunderbird.

I recently deleted a gmail account from my TB. It was a shared account so that account is still open but I have no more need of accessing it. So I went into my TB\Account Actions\Remove Account. It no longer exists on my main TB page which shows my different email accounts. Suddenly, and constantly, I have this window pop up, requesting my login info, which I no longer have. When I close the window, it just opens back up. I have to close it in order to get to my main TB window. It's horribly frustrating. Any ideas??

Several years ago, I switched over to the beta path of Thunderbird... In doing so, I created a new profile for the beta installation, leaving the old one behind in case I wanted to abandon beta... So I had two profile folders; I *thought* they were this:

current profile: c:\notes\Thunderbird original backup profile: c:\notes\Thunderbird.b115

Now, I've decided that there is no reason to retain the old Thunderbird profile folder, since I'm clearly committed to the beta path... however, I have discovered an anomaly... *both* the old and new profiles are periodically being updated!! Thunderbird.b115 is apparently actually my active profile, but Thunderbird was updated just a few days ago.

When I look at About Profiles, I actually see *three* profile folders listed:

Profile: Gorlash: (default: no) c:\notes\Thunderbird

Profile: Derell Licht beta: (default: no) c:\notes\Thunderbird

Profile: Thunderbird beta (default: no) c:\notes\Thunderbird.beta (note that this folder does not exist)

Profile: Thunderbird b115: (default: yes) c:\notes\Thunderbird.b115

===========================================

Is there something that I could do to consolidate all of this into just one folder? I don't even *know* what those Gorlash and Derell Licht profiles refer to... Yes, those are both usernames that I use online, in various contexts, but as far as I know, I don't use them in Thunderbird...

Q1: Can I just delete those other profiles where default is NO ?? Q2: Why is c:\notes\Thunderbird still getting periodic updates, even though those profiles are not default??

I copied my profile from old computer, put TB on new computer, copied the profile to overwrite the profile on new computer- all seemed fine but no names, no email copies, no data. I followed the instructions, no what?

Is there a way to preempt the initial download when connecting an IMAP account initially?

Presuming you plan to make "Keep messages in all folders for this account..." UNchecked, I've found I can only go into settings as soon as possible after connecting the IMAP account to cut off the automatic start of downloads for local email copies. I then search for the email files locally (am configured for maildir) and manually delete.

Not the end of the world, but seems a bit janky. Is there a way you're supposed to be able to set synchronization settings BEFORE Tb starts syncing?

Thanks.

Recent new system. Previously used Office Outlook and backed everything up to a PST file. Found I couldn't import into Thunderbird, needed to install Outlook first and import it there. Did that. So I have an Office 365 Subscription active and have Outlook active. Now I'm trying to get those messages to Thunderbird, but when I go to Import and select Import From Outlook I get a red error "No profile found" and can't continue. Is there something I need to do regarding Outlook for Thunderbird to recognize it?

Hi, When installing my Yahoo account in F-bird, I chose the option to keep copies of the messages on the server when downloading them to my local folders. But all my message folders on the yahoo server appear to be empty after I copied them to my local folders. Can this be undone? I'm using other email programs on my mobiles and it's crucial for me that I can access all my folders from mobile and desktop devices. Is there a way to keep them on the yahoo server AND have them synchronized with my local folders? Your help is very much appreciated! Kind regards, Pat

I am using MacOS 10.13, Thunderbird 115.15.16ESR: my Hotmail worked until 15 May 2025 and then it would not download new emails. Screenshots are available if you want me to post them. I got an error message: "authentication failure while connecting to server outlook.office365.com". I updated Thunderbird to the latest for my OS: 115.18.0ESR. Still no new emails. I deleted my email account on Thunderbird and tried to reinstate it. Now I get an error message when trying to set up the account: "Unable to log in at server. Probably wrong configuration, username or password." I tested my password by logging into my Microsoft account with it on my browser. I can also login to my email using Firefox, but I want my Thunderbird email client to work again.

The configuration I am using is: I use my normal hotmail password in the password field. I also set up a new App Password with Microsoft and tried that without success. With the 115.18 update there is a new field: Your login. I just put my hotmail email address in here. incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 
outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2 (I have also tried: smtp-mail.outlook.com)

I enabled 2-step authentication with Microsoft in my Microsoft account more than a year ago. Interestingly, I don't get a prompt on my iPhone Microsoft Authentication App when I select Done when trying to set up the hotmail account on Thunderbird.

Please help. I am desperate, and I have wasted a lot of time on this without success. Cheers

Dodałem swoje konto pocztowe Microsoft z końcówka hotmail.com, do tego konta mam jeszcze alias Outlook.com, ponieważ używam prywatnie i służbowo z różnych aliasów. Po dodaniu konta hotmail, nie mogę dodać Outlook, wyświetla się błąd konfiguracji poczty wychodzącej.

Hi everyone,

I could really use some help with Mozilla Thunderbird.

I had my official email set up in Thunderbird using a POP3 connection. Before I updated Windows and reinstalled Thunderbird, I backed everything up — all the emails and settings.

Now, after reinstalling Thunderbird, I’m trying to get my old emails and account settings back, but I just can’t seem to make it work. I tried copying my old profile folder over the new one, but nothing shows up properly.

I’m not sure if I’m doing something wrong or missing a step. Can someone please walk me through how to properly restore a POP3 email backup in Thunderbird? I really need to get my old emails back.

Thanks a lot in advance!

At some stage, one of my Imap Inbox email accounts & its sub-folder have moved to the bottom of the list - under all other folders (Sent/Junk, etc). The Sent sub-folders for this email account are in the correct place. I have tried all solutions that I have found: Subscribing; unchecking only show subscribed; playing with the settings on the webmail server, reinstalling, etc & I still can't get it back to the top, where it's supposed to be. I have attached a screenshot as it was & how it now is (worse) after updating my OS to the latest. Does anybody have a solution for this scenario?

[Latest TB on MacOS Sequoia 15.3.1 (just updated from previous version).]

Hi all, I'm using TB 115.18.0 (64-bit) and I am currently working on finding a solution to automatically back-up my mails from two accounts on regular base. I want to back-up the ImapMail-folder from within the profile-folder; while looking into it I found not only the two folders for the current accounts, but also 3 more, for accounts I had in use a few month ago, when I started to use TB and fiddled with it. As I do not want to waste space with unnecessary Data, my question is: can I safely delete these obsolete folders and their associated .msf-files?

Thanks for any help/advice
