dear all, thunderbird corrupted on my 2nd laptop. So I installed tb 128.5.2esr (64) new on this laptop. I Installed t-online accounts for 2 users -> all ok. tried to install web.de accounts for 2 users -> fail with both. I used the same settings as in 1st laptop. When I test the web.de account, I get the message, that the email account can not be identified. I activated thiss account anyway:@ I am able to send a message from klsgbkweb.de to klsgbk@web.de and receive it on my 1st laptop. Then the password should not be the problem. On my defect account on 2nd laptop there is however the inbox missing. I receive no emails at all. The same problem with my other web.de email account. I compaired the account setting several times and see no differences. I am lost and have no further clue. All are IMAP accounts: - imap.web.de : 993 - SSL/TLS - smtp.web.de : 587 - STARTTLS Do you have any idea, what else to check / to do? Thx
