Yesterday I installed Exchange 2013 Cumulative Update 1. Today I realised there were many fewer messages in a mailbox (only one) that had In-Place Archive enabled (it was enabled quite some time ago). I soon found missing messages in the archive, which I then disabled in the belief messages would go back to original folders (there was no obvious way to put them back).
Now that archive appears lost. Tried whatever documentation suggested - Connect-Mailbox and through EAC - but the disabled archive does not show up. How can I restored it?
Thank you.
