Thunderbird Support Forum

I have been using Thunderbird a long time and I have emails going back about twenty years. This means that the built in import/export feature is hopeless. So I copied the entire Thunderbird folder to the new computer. I was able to transfer thousands of emails, but when I looked more closely I saw that my new Thunderbird only went back about 2 years. I would be very grateful if someone could tell a way to make it include the missing older emails.

I am trying to transfer my email from one old PC using windows Live Mail (2012) to a laptop with Thunderbird to process the emails. The email server is with a company called Plusnet, and they can send me their own emails, which are received by Thunderbird on my Laptop. All my other emails continue to be sent to the Windows Live Mail on the old PC. Plusnet advise me that the problem is with Windows Live Mail. Any ideas how to resolve the problem? David Owen

Hello.

I read that thunderbird works with Microsoft 365 and modern authentication. I tested with Microsoft 365 accounts and it worked fine. The problems come with an accounting of Microsoft 365 operated by 21vianet service.

I configured according to https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 with the IMAP and SMTP settings from https://support.microsoft.com/en-us/office/settings-for-pop-and-imap-access-for-microsoft-365-operated-by-21vianet-ca51235d-afc5-4d7d-843c-3616a37d5771

It complaints "The IMAP server partner.outlook.cn does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings.'"

In SMTP settings there is no option to configure OAuth2

After Thunderbird asked me to download a new version & I donated money, all my subfolders to the left have disappeared. ALL my information stored/ emails placed in the subfolders are gone. I have sent several requests asking for HELP. This has been so frustrating I do not want to recommend anyone to use Thunderbird. This has nev er happened to me before and I cannot seem to receive an easy solution a t my end. All folders & emails dumbed into folders are gone???? I need HELP Please.....

I have have been unemployed at the time but still donated $$ to support as often as I can and this has happened which has been a nightmare.

Upgraded to the newest version of Thunderbird, 115.11.1 (64-bit) and now I can not get into my emails on bellsouth.net. . Error message "Sending of password for user xyz123@bellsouth.net did not succeed. Mail server inbound.att.net responded: [SYS/TEMP] Server error - Please try again later." I keep trying but same error for two days now. I can get my email on the web (Yahoo mail) ok. I double checked the setting and everything is good and migrated to the new version ok.

I used the same password I have been using for a long time with my Verizon account and now I get this message: Sending of password for user k.machv@verizon.net did not succeed. Mail server pop.verizon.net responded: [SYS/TEMP] Server error - Please try again later. I can open and download my email messages via AOL but it will not recognize my password to allow me to download my messages to Thunderbird.

I have downloaded my Emil to my laptop using thunderbird and then I try to change the name of storage folder to D:\gmail and after that I could not find my previously downloaded email.I need to jknow how I can file my previous downloaded folder.

I have been stuggling to transfer my emails from a windows PC using Windows live Mail, to a laptop using Thunderbird. I have just spoken to my email provider (Plusnet) and they have sent a test email which is received by Thunderbird. But all my emails keep arriving on the old machine. Any suggestions which might help me? David Owen

Trying to use my old profile on a fresh install.

After trying a few things I ended up with an error that the profile couldn't be loaded or was inaccessible.

So I did the following:

1) started the profile manager 2) removed all profiles 3) created a new profile 4) changed the name of the folder in the file system 5) copied my old profile folder to the same spot with the same name that the profile manager gave it

When I started thunderbird, I was just expecting it to load with my old profile.

Instead, I got the Account Setup screen.

I don't want to setup my email account, as I'm worried it will start downloading all my emails, and store them in who knows what profile. I could not see a way to start Thunderbird without it successfully connecting to an email server in this setup process.

Any suggestions for just getting mozilla to start and load my old profile please?

Install of Thunderbird accepted my donation but does not complete the install. It just returned to the donate screen again. If I try to return to the install exe it wont pass the donation screen. I like Thunderbird but not enough to pay twice. How do I get the install to complete? Appreciate any ideas. Thanks

I recently lived thru the Cox-Yahoo conversion. Yahoo webmail has a folder called SPAM..where all the what I call JUNK goes to but in TB but it never gets into the TB JUNK folder..I can only see it on webmail Yahoo..How do I point the TB JUNK to link with this SPAM Yahoo folder please?

Following suggestions from Jame and Matt (Thanks, guys!), I just installed T-Bird 115X on my Win7 computer, and successfully set up my primary e-mail account. I tried to import settings from my existing Outlook 2010 installation, and was instructed to set Outlook up as the default app for email. I did so, but now I get a "No profile found" notification from T-Bird T-Bird. What should I do?

Question 1 - Is this a real version? (as dlsplayed in troubleshooting information) Question 2 - How can I upgrade to version 115,, or do I have to delete and start again? Sub question - if I have to delete what is the best method? I just spent a few days installing and then installing 5 gig of settings and mail from Windows 10; I would hate to do it again.

I installed the Thunderbird software on (2) devices to replace the Windows Mail product. On the first device (Windows 11 laptop) I was able to add all (3) personal email accounts needed (1 Spectrum and 2 Gmail). On the second computer (Windows 11 MS Surface) i was only able to install (1) Gmail account and the Spectrum account. The second Gmail account gives an error when it tries to verify the account with Google giving the error as follows.

400 that is an error. The server cannot process the request because it's malformed. It should not be retried. That's all we know.

Since the settings on both computers are the same for the account and both Gmail accounts work on one computer this doesn't make sense to me. Any suggestions would be helpful.
