Only import specific cmdlets from Exchange?

I have a script that starts a PSSession to exchange server

$exchangeSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://$exchangeserver/PowerShell/
Import-PSSession $exchangesession

Open in new window


The Import-PSSession will work just fine, however, it takes a while. I think it's because it's loading everything Exchange.
Since I'm only running a couple of cmdlets within powershell after the PSSession import, is there a way to only import specific cmdlets?

Such as Get-Mailbox, Get-User, etc.

Hello,

This is very interesting. My understanding of PowerShell is that you cannot do this. Each cmdlet must be part of a module, modules are imported in turn importing each and every cmdlet.

I'm doing a lot of work with DSC Custom Resources at the moment and the same theory applies.

Kindest regards

Michael

Import-pssession has some parameter which will allow you to import specific commands.. I didn't get a chance to test it but you can try and see if it works for you.

import-pssession $exchangesession -type cmdlet -name Get-Mailbox,Get-User -FormatTypeName *

Open in new window

or
import-pssession $exchangesession -commandname Get-Mailbox -formattypename *

Open in new window

Amazing. I appear to have overlooked that part in the MS examples. This link is much more helpful.

Well, interestingly, my theory was wrong:
Importing the specific commands does not make the script load any faster.
It actually takes about 10 seconds longer.
I timed it because I have a Windows Form script driven by powershell and I time based on how soon the form opens up.
Consistently, with the import-pssession importing the entire module, is 10 seconds faster.

I do wonder importing specific commands helps lessen the strain on the server, if the script is being re-run multiple times, however.

Are you sure Importing the session takes the major % of the script starting time? in my experience loading the Exchange Add-in locally on exchange server itself may take 6- 10 seconds depends on the capacity of server. If you think the load time for your script is abnormal then you may post another question including the script to check if anything wrong about the script or to check if anything can be done to make it better.

No the majority of the load time is due to the script in its entirety.
I'm just finding that for some reason, it takes about 10 seconds longer when I change the single line of code that imports the pssession to only import cmdlets (Get-Mailbox, Add-MailboxPermissions, Add-ADPermission)
