I solved it.<br />
It was a problem with :<br />
<br />
Get-ServerComponentState Servername<br />
<br />
The Components ImapProxy and PopProxy were inactive on two servers.<br />
I changed them to active and it works again now on all servers.

Hate to ask but did you start the Services on the other 2 servers? IMAP services are normally set to manual startup in Exchange 2013

Hi Experts,<br />
<br />
I have 3 exchange servers in a DAG EX2013.<br />
On one Server I can connect via POP and IMAP but not on the others.<br />
When I test via TEST-IMAPCONNECTIVITY just on my EXCH02 I get an SUCCESS event.<br />
<br />
Any ideas why it s not working on the other exchnage servers ?
