Exchange 2010. How can I transfer a letter from one mailbox to another using the API?

Question

Microsoft Exchange

Hey!
Does anyone know how, using the API, you can transfer a letter from one mailbox to another?
Mailboxes on one Exchange 2010
Full transfer, instead of copying is necessary to me.

Answer 1

Move or copy items to another mailbox
You can move or copy items between mailboxes by using the ExportItems and UploadItems operations. To learn more, see Exporting and importing items by using EWS in Exchange.
https://msdn.microsoft.com/RU-RU/library/office/dn...
Apparently, there is only the ability to export / import, the link is above 13, but 10 also has Export(Import)Items https:/ /msdn.microsoft.com/en-us/library/office/ff...
MoveItem only works in a mailbox.
"I need a complete transfer, not copying." But how to copy?

Answer 2

Pavel, thank you very much for your reply.
Haven't tried using it yet.
Do I understand correctly that when exporting from box 1 and transferring to box 2, the letter will remain in box 1?
