How to Send/Receive Email from Gmail account using Outlook 2007 through ISA

Send/Receive Email from Gmail account using Outlook 2007 through ISA

In this post, I will show how to configure Microsoft ISA 2006 to allow POP3, SMTP protocols (for incoming and outgoing messages respectively) which are used by Gmail. Then, you will see how to configure Outlook 2007 client to send and receive email from a Gmail account.


  1. First you have to find out POP3 and SMTP server settings from Gmail. Here are the configuration of Gmail’s POP3 and SMTP at this time (March 2013). I don’t think these settings would be changed regularly:
    • POP3 server address:
    • POP3 port: 995
    • TLS/SSL required: yes
    • SMTP server address:
    • SMTP port: 465
    • TLS/SSL required: yes
  2. On ISA Server 2006, there are already pre-defined secured connection (SSL) for POP3 and SMTP protocols which are POP3S and SMTPS. Now you can begin create an access rule to allow these protocols for your internal network. For more information about creating an access rule on ISA Server 2006, see Getting started with Microsoft ISA Server 2006, Part 8: Create Web Access Rule
    Note: If you don’t have internal DNS, don’t forget to create an access rule to allow DNS protocol. Otherwise, you won’t be able to receive emails.
