How do I move specific archived messages from one archive to another?
Environment details: Exchange 2010 SP3, Enterprise Vault 10.0.1.1171
Situation: we have one user who has been using his personal mailbox as a departmental archive which entails 10 years of data. He was storing all messages sent to firstname.lastname@example.org and email@example.com in his inbox folder and multiple subfolders.
After discovering this, I had him create two subfolders: mailinglist1 and mailinglist2 and move all messages relative to each. I created a shared mailbox and moved all messages sent to firstname.lastname@example.org to the sharedmailbox\inbox\mailinglist1 folder and all messages sent to email@example.com to sharedmailbox\inbox\mailinglist2.
What I need now is to physically move, not copy, all archived messages send to mailinglist1 and mailinglist2 out of the user's archive and into the sharedmailbox's archive. How do I accomplish this?
