Thunderbird Support Forum

I just replaced my 5 year old Windows computer with a new Windows computer. When I loaded Thunderbird on my old computer I had issues receiving my e-mail. My e-mail provider tech support was able to get me set up so that my e-mails went to a G-mail account and were forwarded to the computer. I used this setup for approximately 5 years. During that time I created several folders in Thunderbird and they have several important emails stored there. I setup my new Windows PC this past week and downloaded Thunderbird. To my surprise, I was able to set the program up so that it works without having to go through G-Mail. My issue is that I want to copy the e-mail folders and my address book from the old computer and move them into Thunderbird in my new computer. I have looked at your support page and I am concerned that when I move files from the old to the new that I will lose some e-mails and the few folders that I have on the new CPU. I would appreciate your direction and instructions on what I need to do to accomplish this task. The old computer Thunderbird files were up to date. Updates were completed as they came out. The new Thunderbird appears very different than the edition that is on my old machine. Thank you for your assistance.

Haven't been able to download incoming emails on this laptop. They are downloading on my Tablet. I'd be grateful for any ideas about what I can do to rectify this. Not too complicated - I'm 83!!anks

Hoping something will turn up on my Tablet Th

Hi, I kept OS Snowleopard around for years too long in order to keep using Eudora. I finally got fed up with viruses/crashes, having to rebuild the mailboxes, but I was never able to find anything to take its place and have frankly been limping along ever since. I regularly need to find things going back months, years, and even decades. It used to be simple with Eudora. Recently, one of my parents passed away and I'm kind of the family scribe, so I really need to pull together all the past communications, from Eudora (going back to almost 1990), gmail, yahoo, my website, icloud, my college alumni address, my Ronin Institute address, my 15 Sonic addresses--and there's probably a few I'm forgetting offhand. I really need to consolidate them. I tried various email clients, including years ago a previous version of Thunderbird, but they were a lot of work to set up and couldn't handle all the email addresses.

I see better reviews of Thunderbird now. Can Thunderbird really handle all those email addresses? Since my Eudora mbox files are still on OS Snowleopard, and I'm running Macbook M1 with the latest OS now, what's the best way to incorporate the entire archive of messages and also start hopefully wrangling current messages (like I haven't been able to since I had to stop using Eudora)? Eudora pretty much only did POP well, and I actually did appreciate having my data on my own computer, but now there are some email accounts I'd prefer as IMAP and others as POP. Is it possible to mix them? Is it possible to download AND keeps messages available for viewing by phone? This situation has been a problem for me for years--I was just wondering if there might be any volunteers at Mozilla who might be willing to spend a few hours on the phone with me to help me bring my email into the 21st century? Nearly every day of my life I have to let someone down over something I can no longer do or find because I don't have Eudora. But the problem doesn't go away just because I find another program that does some of the things Eudora did--I really need some help integrating everything. Thanks so much for all you do!

Hello community, Is there a solution to integrate a Microsoft Exchange email account into Thunderbird? It simply does not work, because there is neither POP3, nor IMAP, and also no certificate. :(

Thanks and best regards

After crash, I had to reinstall Windows. After I enter correct address and password, Thunderbird won't connect. I suspect that my two party authorization set up with mail.com is the problem. Thanks

Hi Folks, downloaded the new Thunderbird version 115.3.3 (64 bit) a few days ago. Since then I have not been able to get that version to download my emails from xfinity. I have updated xfinity to allow Third Party Downloads as identified in a prior search but nothing has worked yet. Thoughts? Thanks for any help you can provide!

My Plusnet Mail account is fully operative out of Thunderbird in Windows 10, alongside my outlook.com mailer. I am attempting to duplicate this in a new Win 11 PC and finding it difficult to duplicate my Win 10 Server Settings, due to the ambiguities thown up in hoping to duplicate the Win 10 Tbird 'Server Settings' in the Win 11 'Set Up Your Existing Email Address' questions page.

Win 10 Tbird set-up page confirms my POP Mail Server as 'POP', 'relay.plus.net' and 'Port 110', the Outgiong Server as 'smtpmail.plus'.net' and Username as '"my-name@plus.com".

The Win 11 Tbird 'Server Settings' page (after my own inserted Mail address and Password) includes: 'Incoming Server' protocol as 'POP3' Host Name: (auto-selected) '.plus.com' Port: (empty) Username (empty) - I elected to insert email address "my-name@plus.com".

'Outgoing Server' Host is (again) 'plus.com' Port - empty - and finally (again) ' 'Username' (empty and complered as before with) "my-name@plus.com"

Note: Despite the (fixed) message "Thunderbird will attaempt to auto-select blank fields", the final result advises: "Thunderbird failed to find the settings foryour email account".

Am I making wrong assumptions as to what should be inserted?

After having tried to learn to love Supernova for several months, I cannot. In fact, I have come to loathe, despise and detest its user interface. Are there settings in Views that will give me the old look and feel? Is there a skin I can download. If I cannot I will leave TB after decades of use even if I have to go back to (shudder) Outlook.

Thunderbird 115.0 on Linux/Debian is unable to verify and install addons from website. It just freezes when I try - and cannot even manually install addons that I download using Chrome. I even totally deleted all files and folders and reinstalled Thunderbird 115.0 from stratch... what happened?!

I found that after total removal - if I install a earlier version... that I can verify and install addons, but not with version 115.

I also found that I cannot import profiles from zip or even uncompressed folder. I confirmed the profile is less that 2 gig (1.2 gig) - so size of the profile should not be a problem.

Earlier this week, when Thunderbird updated, I lost access to Thunderbird on my PC. The program is not on my PC. However, I can still get my email on my iPhone and the cloud.

How should I restore Thunderbird? Should I just download and reinstall it? I just want to make sure I still have access to all my old emails and contacts.

Thanks! (a long time Thunderbird user)

My thunderbird just upgraded to 115.2.2 (32-bit) - my windows is 64-bit - but I can't read the preview window or emails. Everything is in a gigantic font so I see only 2 lines at a time in both the main email edit screen and the preview screen. I tried changing it to Calibri 12 in Settings (it was Calibri 17) but that makes no difference. I also don't like that I have to go through File menu now to get messages for just one account. Is there a way to downgrade back to my old version? I guess that would be 115.2.1. Thank you!

My thunderbird just upgraded to 115.2.2 (32-bit) - my windows is 64-bit - but when I create a new folder:

(1) It does not copy the headers from the other folders, as it used to, which is not the end of the world -- I'm just forced to re-create them (which has never happened before in all the years of upgrades) (2) Under the Account header, it should show the email a/c I used to send that email (or the a/c that received that email) but instead it just displays "Local Folders"

I need to know which email it was sent from/received at. How do I get it to display the email account and not "local folders"? Thank you!

I've just moved to Fedora 39. First tried installing the official fedora Thunderbird through discover and Thunderbird found my profile, created menu links to calendar, chat, address book, tasks, but they go no where. Uninstalled, tried the flatpak. Initially my .thunderbird file was not found and I had to manually relocate it into the new flatpak Thunderbird folder. Thunderbird then found my profile but calendar, chat, address book, tasks are STILL missing even though their menu links exist.

I've searched for solutions and in every one of them I have some important missing part i.e. lightning listed in addons(to remove and then re-add, its not listed there so I can't), find the "extensions.installedDistroAddon.{e2fda1a4-762b-4020-b5ad-a41df1933103}" in my advanced settings - remove (no remove setting, only true or false, a sub menu where I can set its type, and a trash).

Any advice?

Recently my C/Windows drive (Solid state) failed, I have the data (it was installed on the D drive of my computer) for Thunderbird however my profile as far as I can tell was stored on my now gone former C drive, I need to recover those emails as I had several personal messages from a departed friend that I had saved as well as a number of emailed receipts for travel etc for the business I am building that I need to use as write offs on my taxes. How do I recover and/or more specifically re-integrate the previous install into my current one?

System is win 11, latest TB, personal gmail account of long standing. I want to use TB as my email program for gmail. After installing TB, it asks for my gmail login and password, and recognizes the account, defaulting to IMAP, Oauth2, etc. When I press "done", I get a google screen saying that TB want authorization to access gmail files. But when I press "allow", the TB page shows an error message under the password field reading "Unable to log in at server. Probably wrong configuration, username, or password." I understand it is looking for my gmail username and password, and these are correct. I have tried this many times, including with variations: removing and reinstalling TB, creating a pw just for TB in gmail (subsequently deleted). I have read all of the gmail installation help notes at Mozilla. Most relate to a 2022 change in gmail re Oauth2. Nothing helps. Any advice?

I'm trying to migrate old messages (stored under pop) in an outlook .pst.

choosing Tools, Import, then selecting Import from Outlook, immediately gives a "No Profile Found" above the import tool.

I'm not even clear if this is referring to a Thunderbird profile, an outlook profile, or possibly a file in an import directly somewhere?

anyone have suggestions?

When I try to set up Thunderbird on a new computer, it won't connect. And Thunderbird changes the port settings that the provider uses to something else. So I can't use thunderbird with my email address: sheilah@got.net

Hi Mozilla Thunderbird Support team,

My name is Naoko Ochiai. Since Nov. 21, my mail application has stopped receiving and sending emails. I think I haven’t updated it at all. I should reset or uninstall it and reload for the recovery. Please tell me how I can make the mail software work again.

Best wishes

Naoko Ochiai

I am getting an error that "you have launched an older version of Thunderbird" Every time I try to open my email. I was using the latest beta version up to three days ago and the program got corrupted for some reason. I did try to install the latest beat online beat 2 .

Thanks, Al
