I am having trouble accessing my Exchange account using Microsoft Outlook from my home and off-campus. Why is this?
In most cases, this is due to restrictions put in place by your Internet Service Provider (ISP). The blocking of certain ports is a common tactic used by ISP's to stop the spread of worms/viruses to vulnerable computers on their networks. In addition to blocking these worms, Windows file sharing, Microsoft Exchange email & calendaring, and other U-M services are also blocked.
In order to bypass these restrictions and access your Exchange account, there are several options as described at:
U-M set up a remote VPN connection service. This service provides a secure way for U-M faculty and staff to connect to the U-M network from off-campus, and obtain access to campus resources. See this page for more information:
