hallo, two weeks ago my "Arcor-account" on Thunderbird indicated "timeout" and I couldn't send or recieve messages. Then I deleted the account on Thunderbird and tried to reinstall. But that doesn't work. Thunderbird found the settings of the adress, but when confirming it, they said the settings or password are wrong, what is definitely not the case. The Arcoradress is very old, Arcor belongs meanwhile to Vodafone. May be that causes the problem. I failed also on trying to install manually.

Thank you for helping me best regards Uwe
