Thunderbird-Hilfeforum

Hello, my Cox email account was migrated to Yahoo mail. I can receive emails but now I can't send emails from Thunderbird. I've triple checked server settings. Please help. Thanks-Vince

This is the message I get and it does this with all email addresses.

Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

hi

I made a mistake to uninstall thunderbird  due to a few issues . now the new version is refused to be installed 

my version was 15-321OM ,,cpu thank you regards

I imported info from Thunderbird on other computer. Now every time I open Thunderbird on the new laptop it says it can't reach my email server, incorrect login. If I enter my password it repeats the failure message. If I just close the message, the popup appears again, closing it again, it repeats once more, then closing it keeps it gone. Once I get the message to stop popping up by the repeat closings of the message, the related email account has already collected new emails so it was working. For what it's worth, the laptops are both Lenovo, the old is running Win10, the new Win11. Before the Import is was working fine, I only wanted to transfer my contacts, but the export grabbed everything. I don't have the issue on the original laptop I exported the info from.

Hi!

Trying to use Thunderbird to connect to my hotmail account but get an error message that says I can't log into "server" due to the prefs or login details are wrong. Have tried to search around for answers but can't see that anything is wrong. Any idea what to do? Use windows 10 professional.
