Exchange 2007 SP1 Item ids

Exchange 2007 introduced a new URL format (Constructing OWA 2007 item ids from WebDAV items) which contained an arbitrary item id, which was based on the EntryId of the item. The format was this:

Length Meaning
1 Length of the structure
sizeof(EntryId) EntryId
1 Item type

This format changed with Exchange Service Pack 1. The layout is now this:

Length Meaning
4 Length of the user's email address
sizeof(EmailAddress) Email address specifying the mailbox which contains the item
4 Size of the EntryId
sizeof(EntryId) The EntryId of the item

This layout also applies to folder ids within a mailbox.
