Hello, here’s the problem: I had / have 3 GMX mailboxes in Thunderbird on my PC. After I installed Thunderbird Mobile and spent several hours with it, I deleted all the mailboxes to import them again. Apparently, this also deleted all the mailboxes on GMX, as they are no longer visible there. I also can’t create new ones there, as the old ones seem to still be somewhere in the Background. In Thunderbird Mobile, I restored the mailboxes via import, but they are completely empty! Thunderbird Mobile has no connection to GMX. What can I do? I go to bed...
