I tested the program on one account and it worked great but when I
clear the registration and try to install it on the actual user’s outlook it is giving me a strange result.

It keeps telling me: Failed to save ”subject of appointment”.

I can see the records in the database so I don’t understand why this is so.

I have a Terminal server running with Outlook 2003 connecting to a Exchange 2003 server.

I figured it out. I have multiple mailbox stores on my Exchange server. It only works with the default mail store. I moved the user to the default and it works beautifully.
