The information in this article applies to:
  • Microsoft Exchange MS-DOS client, versions 4.0 and 5.0
  • Microsoft Exchange Windows 3.x client, versions 4.0 and 5.0

SUMMARY

Microsoft Exchange clients can connect to Microsoft Exchange Servers over the Internet via third party Internet Service Providers.

In order to connect from a client, you must:

  1. Have dial-in or direct connection to the Internet.
2. Be validated by the Microsoft Exchange Server's NT domain in order to 
   talk to Microsoft Exchange Server via RPCs. To verify this, clear the
   Use Network Security During Logon checkbox. This will require domain
   login credentials when you start the Microsoft Exchange client with this
   profile.
3. Put the Microsoft Exchange Server name in the client's HOSTS file with IP 
   address.
4. Have the ability to ping the Microsoft Exchange Server by server name

MORE INFORMATION

Connecting Microsoft Exchange clients to Microsoft Exchange Servers over the Internet is similar to using a large WAN. However, TCP/IP port 135 needs to be enabled on all routers and firewalls in order for RPC communication to work. Use RPCPing.exe on the server and client computers to verify this.
