I'm getting the error below when trying to expand the tree for MS Exchange Systems Manager v. 2010.
The following error occurred while searching for the on-premises exchange server:
You cannot call a method on a null-valued expression. It was running the command 'Discover-ExchangeServer -useWIA $true -SuppressError $true -CurrentVersion 'Version 14.1 (Build 218.15)".
Anybody know what this is and how to resolve it?
