Office Outlook 2003 SP2, running in cached Exchange mode, with Business
Contact Manager.

My messages are categorised by a rule as they arrive depending upon the
account through which they were received.

If I respond to email as it arrives, a message appears in the grey
notification area of the original message (between the toolbar and the from
field) saying:

"You made changes to another copy of this item. This is the most recent
version. Click here to see other versions."

If I click to see other versions, a version which has noted the fact that
I've replied to the message appears. If I replace the existing item with
this version the item that is left is not categorised.

This is not much of a problem, but it is annoying. Has anyone else
encountered any similar behaviour?

Many thanks,

Tom
