Question : Out of Offices Replies not sent to external email accounts

I have a server running Microsoft server 2003 SBS.

When a user puts up and out of office reply, the message is sent to internal users, but not to users outside of the network.  All clients are using outlook 2003.  

Settings for Internet mail in the Exchange Systems Manager have been checked and are allowing out of office messages to be sent.

Any ideas what else to check for?

OK - if you must then:-

Using the Exchange System Manager, open Global Settings > Internet Message Formats, right click "default" (on the right hand panel). Select Properties > Advanced. Tick the "allow out of office responses" box.
