Mark exchange mailmessage as read (not on initial get-messages activity)

Hi all,

Is there a way to mark an exchange mail message as read - but NOT when initially performing the get messages activity? I want to be able to perform some actions on the message first, and then mark it as read. I have tried changing the Header(“IsRead”) to true, but that change doesn’t seem to get sent back to the server. Is there a way to send the change back to the server?

Thanks!
