Microsoft Dynamics CRM 4.0 E-mail Router deployment guidelines
The E-mail Router is an interface between the Microsoft Dynamics CRM system and one or more Exchange servers or POP3 servers for incoming e-mail, and one or more SMTP servers for outgoing e-mail. E-mail messages come into the Microsoft Dynamics CRM system through the E-mail Router.
Install the e-mail router on a dedicated machine and Configure all users in CRM to use the E-mail Router for both incoming and outgoing e-mailConfigure the “info” CRM queue to also use the E-mail Router for both incoming and outgoing e-mail.
Both users and the queue will allow the E-mail Router to send and receive e-mail on their behalf (users do this via their personal options page, queues allow this directly from the queue entity page)
Single profiles for Incoming and Outgoing e-mail will be configured in the E-mail Router Configuration tool. These will be configured to use “User supplied credentials” for connecting to the individual mailboxes. The incoming profile will use the POP3 e-mail server type option.
