We just installed Exchange 2010 SP3, then also installed Update Rollup 5. The main reason for this was to make use of the New-PublicFolderMoveRequest for a custom system we have. However trying to test it this morning it's saying the cmdlet isn't found, and when you list them it doesn't show up. Based on the link below however, it should be there.

Is there something else I'm missing to use this?
