Hello,

I'm currently trying to configure IMAP on our Exchange 2010 servers.

I've started the Exchange IMAP service on the Client Access Servers and when i'm using a telnet client to connect to port 143 i'm getting the banner string "The Microsoft Exchange IMAP4 service is ready." back. Connection is made. The test account i'm using is imap enabled. When i try to configure my local outlook client, outlook asks my several times for my credentials and when i'm in luck the connection is made succesfully. But usually it takes so many times that i've closed the client out of frustration.

Does anybody know what settings i can check to get IMAP working on Exchange 2010? Our Exchange 2007 servers work fine with IMAP. (we are in the middle of a migration).

Best Regards,

Sidney Mulder
