I just applied SP3 to my management workstation (our Exchange server is still on SP1) and I get an error:
"The term 'Get-LinkedRoleGroupForLogonuser' is not recognized as the name of a cmdlet, function, script file, or operable program."
I'm assuming the issue here is that I haven't yet upgraded the server to SP3 (that is planned for Saturday), but of course now I'm a little wary about the upgrade...
I can connect just fine using the SP1 EMC.
