I am so frustrated with Thunderbird I'm about to give up and find another app. I had to reload Windows 11 on my computer and before I started I saved all the Thunderbird info as instructed by support. Now that I am back up and running I'm trying to get Thunderbird back. When I down load a new version of Thunderbird it sees that I did have an account in the past and wants to use that info again. I get to a page where I have to put my full name in, then my email address and then a password. The only password I can find in my password folder(real paper) I can only find a Firefox password. I put that in and continue. It recognizes the password and shows me the info it wants to use for my account. I click on "done" and it starts looking for a password again. After a long search it comes back with a yellow box and says "its unable to log in at server. Probably wrong configuration, user name or password." I've tried changing the Primary password but get no results, not able to. Tried uninstalling and running the version I have stored from before the Windows reinstall and I always end up in the same place......I've been banging my head against the wall on this for several days now and am ready to use Microsofts software instead...... Any ideas before I delete and give up on Thunderbird???
