Summary: Speed up the connection to Exchange by importing only the cmdlets that you need.

Hey, Scripting Guy! Question Is there a way to speed up the initial PowerShell connection to Exchange?

Hey, Scripting Guy! Answer Yes, of course! With a little modification to Import-PSSession, we can speed up the connection. Normally, you would connect to Exchange

like this:

Import-PSSession -Session $session

This would import all available cmdlets in the local PowerShell session. But, consider the next example:

$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri 'http://ex0http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/2019/04/2010_scriptgames_badge1.png9/04/hsg_perf3_02.jpg9/04/hsg_perf4_0http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/2019/04/2010_scriptgames_badge1.png9/04/hsg_perf3_02.jpg.jpg9/04/hsg-02-http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/2019/04/2010_scriptgames_badge1.png9/04/hsg_perf3_02.jpg9/04/hsg_perf4_0http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/2019/04/2010_scriptgames_badge1.png9/04/hsg_perf3_02.jpg.jpg7-http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/2019/04/2010_scriptgames_badge1.png9/04/hsg_perf3_02.jpg9/04/hsg_perf4_0http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/20http://devblogs.microsoft.com/scripting/wp-content/uploads/sites/29/2019/04/2010_scriptgames_badge1.png9/04/hsg_perf3_02.jpg.jpg0-03.jpg9/04/questsoftware.png9/04/a-sm.jpg9/04/q-sm.jpg/PowerShell/?SerializationLevel=Full' -Authentication Kerberos
Import-PSSession -Session $session -CommandName Get-Mailbox,New-Mailbox,Enable-Mailbox,Set-Mailbox -FormatTypeName *

This would import only those cmdlets that you use, and this speeds up the import itself. This same kind of trick works also for the Active Directory module:

Import-Module -Name ActiveDirectory -Cmdlet Get-ADUser,New-ADUser,Set-ADUser
