Strange Problem.

I have stored 4 accounts on my iPhone and get mails only from 3 from the same PO.
With my own account "rupert" I get a message:"Server mail.company.at does not respond"
But i can send mails with my account very well.

This error occurs after moving all users into a new postoffice.
But all other user accounts are working well.

On the iPhone I have checked my own password, mail address, port and so on.

I have deleted my account in consoleone and create it new. Connected with the existing PO-User "userqtn.db".

On my workstation i can login with Groupwise-Client 8.0.3 without any problems.
The Groupwise Client works well and it must be a problem with my user ID and IMAP.

But I do not find the error.
What could be the reason for this problem?

The POA shows me the correct login:
09:30:55 0FA8 IMAP-Anmeldung GW-Benutzer-ID:[icom] von 192.168.101.12 IMAP-Befehl:["***"]
09:30:56 14CC IMAP-Anmeldung GW-Benutzer-ID:[rupert] von 192.168.101.12 IMAP-Befehl:["***"]
09:30:56 14CC IMAP-Anmeldung GW-Benutzer-ID:[sr] von 192.168.101.12 IMAP-Befehl:["***"]
09:30:56 14CC IMAP-Anmeldung GW-Benutzer-ID:[admin] von 192.168.101.12 IMAP-Befehl:["***"]
