I was going through the laborious task of manually importing PST files into Exchange 2010 SP1 beta and I hit a bug:

Error:
Error was found for (username) because: Error occurred in the step: Approving object. An unknown error
has occurred., error code: -2147221219
+ CategoryInfo          : InvalidOperation: (0:Int32) [Import-Mailbox], RecipientTaskException
+ FullyQualifiedErrorId : CFFD629B,Microsoft.Exchange.Management.RecipientTasks.ImportMailbox

Here is how I worked round it.

With the new online Move-Mailbox functionality in Exchange Server 2010, invoked by calling the New-MoveRequest cmdlet, the time a mailbox is offline has been reduced to only seconds, and as such the end-user experience has been greatly improved.

There’s a mystery about early Exchange 2010 deployments:  despite the much-publicized removal of single instance storage, sizes of Exchange 2010 databases have not increased. The same message has trickling back from all quarters, as businesses go live:  after moving mailboxes, database sizes in Exchange 2010 are roughly the same as they were in Exchange 2007.

In a previous article I mentioned how to create users and computers in active directory, the first stage of testing the PST Importer (and ESA). The next step is to go to Exchange and create mailboxes to the users that we just created and for further comfortable management, add access permissions to them where needed.
