Hello,

May I know how you are trying to connect IMAP from email client? By design it will not allow you to use normal IMAP you have to use IMAP over SSL (TCP 993). Although as an Admin you can change it to allow plaintext authentication as well and need to modify binding of IMAP protocol accordingly.

Regards,
Sanjay Santoki

Hello Sanjay.

Yes - i test it from an E-Mail Client and use the Exchange-Shell cmdlet (test-imapconnectivity -ClientAccessServer:irrsee -MailboxCredential(Get-Credential innovations\
hilfe) | fl).

For the user "ko" it works, other users not. Is there anything to configure in the userprofiles so they can use IMAP or POP3?

It isn't a problem with SSL or not. It works with the user "ko" but not with others.
