This is one topic that i faced when Exchange 2010 was released…

So for the Export-Mailbox and Import-Mailbox commands to work, you have to enable them:

1. Open EMS ( Exchange Management Shell ), and check if you have the Exchange Server Admin Tasks installed by running this command:

Get-PSSnapin

2. In most of the cases you will not find it in the list so you have to run the next command:

Get-PSSnapin -registered

3. Now you have to install Admin Tasks for the Exchange Server, by running the command:

Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010

4. After you ran those commands, you can enjoy the Export-Mailbox / Import-Mailbox:

ENJOY.
