How do I get a mail item's MessageID Bickers 2/5/2007 9:42:00 PM Hi, I need to track messages in a database, but be able to handle the same message being sent to multiple recipients (within an Exchange environment). I know that all messages sent to multiple recipients will have the same MessageID value, but I can find no information as to how to retrieve it. What I'm planning is that when a message is opened, an AddIn will check whether the message has already been handled and if not, store info in a database (simplistic view). When another user reads the same message, I need to be able to detect that it's already been handled. Thanks for any help, Phil.

Re: How do I get a mail item's MessageID Bickers 2/6/2007 8:15:02 PM 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.

Re: How do I get a mail item's MessageID Bickers 2/6/2007 8:17:01 PM Thanks Dmitry. Is that the MessageID visible in the headers of a message ? What about a message sent via Exchange (ie within an organisation, without going out to the internet) ? Does Exchange assign an ID to sent messages ? Cheers, Phil.

Re: How do I get a mail item's MessageID "Ken Slovak - [MVP - Outlook]" <kenslovak[ at ]mvps.org> 2/6/2007 8:47:59 PM EntryID can change if an item is moved, it depends on the store provider.

Re: How do I get a mail item's MessageID "Dmitry Streblechenko" <dmitry[ at ]dimastr.com> 2/6/2007 9:01:22 PM AFAIK as of Exchange 2000 (or was it 2003?), the id will be set on the messags sent by an EX server.
