outlook taskItem entryID problem

[Guest]

Hi,

I am creating TaskItem in outlook by using C#.
I got the entryID from the taskItem when it was saved.
But later after the taskItem was moved to another MAPIFolder by
using the TaskItem.MoveTo(folderName), the entryID of the taskItem
was changed ? But why it was changed ? I know that the entryID should be
unique within the same store and the MAPIFolder is within the same store.

Thanks

EntryID's can be changed when the item is moved depending on what store
provider you're using. A PST doesn't do that but an Exchange mailbox does.
