You uninstall an update rollup or an interim update on a Microsoft Exchange Server 2007 Edge server. Then, PowerShell commands that are used for the Edge server role do not work as expected. For example, you may receive the following error message when you run the Get-AttachmentfilterListConfig cmdlet:
The term 'Get-AttachmentfilterListConfig' is not recognized as a cmdlet, function, operable program, or script file. Verify the term and try again. At line:1 char:30 + Get-AttachmentfilterListConfig <<<<
This problem occurs because the uninstallation process incorrectly resets the CustomPSSnapInType registry entry.
