Our current windows OS phones connect to our exchange 2000 server via IMAP.
This exchange server is going down (yeah).
So, from the notes on mobile, what ports am I opening up for our phones that connect to the 'fake' exchange server (really connecting to zimbra)? I am beliving that this is not IMAP. Am I wrong. Need help.
I'm searching for this in the forums and wikis.
Thanks in advance,
