Hello,
I have been requested to restore some emails from ex-employees with a particular phrase match for a court subpoena. These employees mailboxes have been removed from Exchange long ago.
Using the Enterprise Vault service account I can successfully perform a search on relevant mail archives and create a basket of relevant archive items. I have enabled the export to PST option from web search. When I attempt to export the basket to PST, the operation fails and I see Event ID 2227 errors in eventlog with description "User '<unavailable>' failed to restore an item into mailbox '<unavailable>'"
As the employees mailbox does not exist, I am entering server name and mailbox alias of the Enterprise Vault Service account.
Does anyone know if what I'm attempting to do is possible or because the relevant mailbox to the items I'm trying to restore is no longer in existence that this is not possible? My only option being to export the entire archive to PST.
Thank you.
