Unable to open cloud based archive.

Dec 31, 2013 at 12:46 PM
Here is the scenario
  1. Primary mailbox is hosted in On-Premise Exchange 2010 SP3 server.
  2. Archive mailbox is hosted in cloud.
This is in hybrid scenario.

I'm getting 401 unauthorized, while opening to archiveRoot or archiveMsgFolderRoot using EWSEditor.

Can we open cloud based archive mailbox using EWSEditor? I think this is not supported.
