All of this assumes you're on TB v 60.9.0 I'm going to make a couple of assumptions here. First: that you've gone to Account Settings and clicked on Account Actions to start the process Second: that you've clicked on "Add Mail Account" If you've done that and then filled in your new "existing" email account, address and password and, since the outgoing is the same, you won't have to fill that in, You should be done! The only complication is if you choose manual configuration which, if you're using the same isp, you shouldn't have to do. So, please advise where your input differs from my assumptions and we'll see what I can do to help.

Thanks for your reply. I tried what you said in my Polish Thunderbird a few times few days ago and it didn't work, but I tried it now again today and for some reason this time it worked. Best regards

Sometimes it takes a restart to urge your computer to cooperate. lol. Thanks for letting me know. I'll be a bit more confident because of it. Oh, and click helpful, if you wouldn't mind. Best regards
