Error (Method not found or Can't generate Export-Module) in Exchange Management Shell and remote PowerShell
Original KB number: 4037313
You may meet the following issues when you use Microsoft Exchange Server 2016 and Exchange Online after the July 2017 security update KB4025333 for Windows Server is installed.
When you open the Exchange Management Shell, you receive the following message in the Exchange Management Shell:
WARNING: Can't generate Export-Module for the current session using Import-PSSession.
When you try to use Windows PowerShell to connect to a remote Exchange Server 2016 or Exchange Online, you receive the following error message in Windows PowerShell:
Import-PSSession: Method not found: 'System.String System.Management.Auomation.CommandMetadata.EscapeBlockComment(System.String)'
These issues occur because KB 3000850 isn't applied. The July 2017 security update has a dependency on KB 3000850.
To work around this issue, install KB 3000850 to resolve the missing dependency.
