microsoft gives an example to move mails to another folder

... works perfect, but what about an inbox that has say 1000 mails, isn't this going to be to slow ?

Answer 1

Hello,

The Outlook object model doesn't provide any method or property for moving a batch of items simultaneously. However, you can use a low-level API on which Outlook is based on - Extended MAPI where you can run secondary threads for long-running operations. Following that way you will avoid any UI freezes and let users work in a usual manner. See MAPI Multithreading Rules for more information about that. Note, you can use any third-party wrappers around Extended MAPI such as Redemption, for example.

looks very interesting, but i'm afraid that i'm not experienced enough

i thought i could somehow directly address the mails in outlook , but that is not possible , is it ?

Answer 3

On the Extended MAPI level, copying or moving messages is always done is batches (IMAPIFolder.CopyMessages(..., MESSAGE_MOVE)) - the method takes an array of entry ids. MailItem.Move simply uses a batch of 1 item.

The only workarounds are either Extended MAPI (C++ or Delphi) and the IMAPIFolder.CopyMessages method or a library like Redemption (any language) - it exposes RDOItems.MoveMultiple method that takes an array of entry ids.
