I'm having the issue.
I tested my ews config successfully via ewseditor
I changed my password to a very simple one.
I suspect we are entering the login incorrectly or SSL incompatibility....
For ssl I tested on a verisign signed cert and on another ews server with a selfsigned cert. both still had issues though.
Pop and imap is failing for me as well... This is so flustering.
does the alertcentral blocking any ports?
ugghhhh
