You can use NameSpace.ExchangeConnectionMode. That returns a member of the
OlExchangeConnectionMode enum. The value olNoExchange (0) is returned if no
Exchange is being used.

Ok, I understand it.

Is it possible to see if Outlook has Exchange attached to it?

The i can disable the code and not get an error.
