Searching Multiple Mailboxes
One of the great features within Exchange 2007 is that ability to do searches over multiple mailboxes. When I used to Administer Exchange systems I was asked many a time to find pieces of information that was buried in mailboxes. This was a long drawn out task and was only usually done after much discussion because of the time and effort involved.
In 2007 this has been sorted allowing you to run a Powershell cmdlet which will search
So to find specific content and then copy to a specific mailbox use
Get-Mailbox –Database DataBase1 | Export-Mailbox –ContentKeywords "Specific text here" –TargetMailbox Administrator@Contoso.com –TargetFolder 'MessageFolder'
Obviously you need the rights to do this but hopefully this will make great strides into your Operational Efficiency and make things a whole load easier
