Hi All,

We are planing to implement Exchange Server 2013 in our origination in split role model. The  Client Access server and Mailbox server  will be in different VLAN, I would like to know which all  port need to open for the communication and configuration of these roles.

1. Client Access server > Mailbox server (bi-direction)

2. Client Access server > Active Directory (bi-direction).

Mailbox server and Active Directory will be in same VLAN

Also

Firewall > Client Access server required port for Outlook,Outlook Anyware, SMTP from spam filter.

Does the Mailbox server required any access to external network or only Client Access server required.
