Thunderbird Support Forum

I just downloaded and installed Thunderbird to use for my email because I have nothing but trouble with the Windows 11 Mail program on my computer. Apparently I've missed something critical in the set up because it doesn't access any of my emails. Even if I try to send myself an email it says the sending failed because the server was unable to access the mailbox. My email address is through Frontier, which uses Yahoo Mail to handle it's email. My email address is xxxxxx@frontier.com. When I check my settings on Thunderbird it has my correct email address for account name and email address, and under server settings it has my correct email address for user name, for server type says IMAP Mail Server, and for server name says imap.mail.yahoo.com. For port it says 993(default). I used to use Thunderbird on a previous laptop, with the same email address, and never had a problem. Can someone tell me what I might be missing? I will admit to being middle of the pack when it comes to being tech savvy, so don't get too technical please. Appreciate any help.

I am receiving the following error message when I try to download messages from my Comcast.net account:

The RETR command did not succeed. Error retrieving a message. Mail server mail.comcast.net responded: Message 41395 expunged.

This just started happening yesterday, and I can no longer download any messages from the account. Comcast has no clue why this is happening.

I have a corrupted TBird profile and needed to reinstall TBird, create a new profile and synchronize it with my Yahoo mail. I have a large number of subfolders below the inbox on my Yahoo mail server and want to make sure those get synchronized into TBird as well as just the inbox messages. Is that happening automatically or do I need to do something "special"

My Dell Latitude originally came with Windows 7, I upgraded it to Windows 10 and I keep getting an error while tring to install the latest version of Thundebird. "sorry, Thunderbird can't be installed. This version of Thunderbird requires Microsoft Windows 7 x64 or newer. Please click the OK button for additional information."

I've just installed Thunderbird, hoping to create a local backup for several years' worth of email on yahoo's server. It dutifully downloaded the last two years' worth... and then stopped. It continues to pick up any new messages that arrive, but nothing I do will get it to download any more of the past messages. What can I do to finish the process?

Very appreciative for any advice! I've been using email for decades, but am entirely new to storing it locally.

speake french please.Je ne peux importer le carnet d'adresses car sur le nouvel ordinateur "reoming"n'aapparait pas apres avoir cliqué sur ouitile de profil

First off, I am using Windows 10 and TB 102.6.1, Thunderbird needs to use the GoDaddy outlook Office 365 server on the Webb. When I try to install TB 102.8.0 or TB 102.9.0 all seems to install fine. When I then go to use TB, I get an error "Authentication failure while connecting to server outlook.office365.com". When I re-install TB 102.6.1, all works again. I'm 76 and this stuff seems to be going over my head. Any ideas of what I need to do? BTW, my account for Gmail mail works fine but does not use any outlook settings
