Hi,

 we have an internal emailer windows application. All it does is get the
email subject, emailto list etc from the database and send the emails. we are
using chilkat dll to send the emails. Also when I looked at the references in
the project I found these references that are related to exchange.

AxInterop.MSMAPI
Interop.Microsoft.Office.Core
Interop.MSMAPI
Interop.Office
Interop.Outlook

Now we are trying to switch from Exchange 2000 to Exchange 2007. When we
looked at the services that doesn't exist in 2007 but in 2000 we came up with
the following list

•    Novell GroupWise connector (Exchange 2003 Service)
•    Microsoft Mobile Information Server (Exchange 2000 Service)
•    Instant Messaging service (Exchange 2000 Service)
•    Exchange Chat Service (Exchange 2000 Service)
•    Exchange 2000 Conferencing Server (Exchange 2000 Service)
•    Key Management Service (Exchange 2000 Service)
•    cc:Mail connector (Exchange 2000 Service)
•    MS Mail connector (Exchange 2000 Service)

We are not sure if any of the above services affect our emailer application.
I mean when we move to exchange 2007 will our windows application break
because of the non-existance of the above services? Or should we change our
windows app to point to new dlls? Please let us know.

Thanks,
