Thunderbird Support Forum

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.

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 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

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

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!

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

I am trying to set up a new email address on Thunderbird but comes up as a POP account. I then set it up on another computer and it comes up as IMAP. I have tried setting up the IMAP manually but Thunderbird rejects. I have uninstalled the app and re installed it.

Can I run Thunderbird 102 (full install) with Supernova portable? I want to see what SN looks like w/o commiting it. If I install SN portable on my Win 10 PC can I later remove it w/o damaging my TB 102?

I am s-o-o-o gd tired of this happening. Every time it does, I spend days-to-weeks trying to recover a working edition of Tbird. Why can't you build updates that don't lock a customer out of his/her own emails.

I don't know how or when, exactly, it happened. I use Win11pro which is up to date. I have one Tbird install on dropbox so I can access all my emails from any of four different machines. It worked yesterday (on two machines at any rate, I didn't use the others). Today, no matter which machine I log into, I get an message stating that I ' you have launched an older version of Thunderbird. A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version. Use this profile only with that newer version, or create a new profile for this installation of Thunderbird. Creating a new profile requires setting up your accounts, calendars and ad-ons again. For more information . . .italic text Then it gives an 'exit' button and a 'create new profile' button.

1) I did NOT install a new version of Thunderbird.

2) Insofar as I can tell, the version on Dropbox has not changed so nothing should have altered the profile.

3) I do NOT want to create a new profile -- I have years of data in calendars and emails across multiple accounts.

4) the 'more information' link doesn't work.

Why do you periodically do this to me, Mo? Why can't you make changes that don't destroy a person's account(s), profiles or data? Why do you put up such a useless message without a utility to restore things to the way they should be?

5) I have been searching the internet for hours and I don't see a solution to this problem.

I had a huge problem with M Outlook. In addition it has locked me out of my Office 365 package and I'm not getting help or support. Luckily I had backup completed before the problem. I changed to Thunderbird (using pop3), which I find very good. The back up is approx 8 GB but with many duplicates which I need to clean up. When I click import it seems to limit the file size to 2 GB. How can I import this backup file into Thunderbird to enable me to access the emails, clean up the many many duplicates and reduce the size? I await help, Thanks in advance

I have Thunderbird installed on 3 separate computers in 3 separate locations. When will it be possible that the 3 installations are all completely identical, i.e. they're clones of each other? I would like the folders, filters and address books, for example, alterable by one one installation to update the other two. (Working like, say LastPass)? At the the moment, any filter or folder not present on one of the installations causes emails to end up al over the place!

I lost my password and had to remove and readded my Suddenlink email, which autodeletes emails past a date and size. I want to have it sync with my local folder inbox only so i can ignore the autodelete off of suddenlinks inbox

I had to replace my hard drive and now have Win 11. I still have my Thunderbird account, but I cannot access the 3000+ emails in my folders. My Thunderbird started from scratch, no history, no files. How do I access and download my saved emails and folders from before the hard drive replacement? The Geek Squad couldn't help. Keep it simple, I'm not a techie.

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

I ask for help with thunderbird and you send me this: If you need help with Mozilla Thunderbird, you can visit the Thunderbird Support Forum or the Thunderbird Support Articles. which brings me right back here. You are worse than windows.

I have bought a new Mac Air and I want to get all the email address off of Thunderbird on my desktop and put them on Thunderbird on the laptop. I have had to move most of my files and items by Flash drive because when I migrated it the first time, I overloaded the laptop and had to start all over. So what file can I move from the library to get these on my new laptop?

Hello Dear People,

I have been using Thunderbird to great satisfaction. When my computer of 10 1/2 years died, I started to use old laptop of my son who made me the second user. I d/l Thunderbird on my account and it all went well till a few days ago. No Thunderbird. I d/l again, profile not found/inaccessible. I did see advice here from last year, looking for the profile under Users, app data, roaming etc. but to no avail. There is no profile.

How to solve this problem? Also after d/l the set-up, the thumbnail looks strange, like half of the image as shown in the picture. I tried d/l a few times, same result. I was very content with the program. I want Thunderbird back!

Thank you for your advice! Dorith

Hi,

I've tried migrating Thunderbird data and folder structure from a Windows 10 PC to a new Mac Sonoma 14.1.2 following the instructions from https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer and encountered problems.

I copied the Thunderbird folder from the PC onto a USB drive and then moved the file to the Library folder on the Mac.

Importing seemed to go well, but when I opened Thunderbird on the Mac only the inbox (and its messages) were there. All other folders and their contents were missing.

What did I do wrong and what do I need to do to migrate all folders/sub folders and their data?

Thanks, Richard
