Remote Exchange Server, Incoming EMail, and Ports
Posted on 2011-02-14
When an organization access an external (i.e. third party) Microsoft Exchange Server for their email and uses MS Outlook 2003/2007 email clients locally (with Calendar Sync), does the incoming email still use the standard POP3 port of 110 ? Or does it use some other port(s) instead of or in addition to port 110 ? A site needs to configure an edge router or firewall device of some sort to effectively scan incoming emails - and on occassion strip certain attachment types.
