EntryID can change if an item is moved, it depends on the store provider.
Internet Message ID's in the headers aren't there in intra-organizational
Exchange emails, only on emails sent via the Internet.

Hi Ken,

I was under the impression the EntryID can change. I need the ID that was
assigned to the message when it was sent.

There is a MessageID in the internet headers, but will that be present in
a
message sent via Exchange ?

Cheers,

Phil.
