Get the Version Number of a PowerShell Module

 

When a PowerShell script works for one person, but not for another, sometimes it's because the PowerShell module is a different version.

To find the version number:

Get-Module -ListAvailable "Microsoft.Online.SharePoint.PowerShell" | 
select name, version

 

If you need to deal with multiple versions in your scripts:

if ( (Get-Module -ListAvailable "Microsoft.Online.SharePoint.PowerShell").
  Version.ToString() -eq "16.0.4915.0") 
  { … do this } 
else 
  { … do this }

or maybe

if ( (Get-Module -ListAvailable "Microsoft.Online.SharePoint.PowerShell").
   Version.ToString() –lt "16.0.4915.0") 
   { "Must have 16.0.4915.0 or later"; Return; }
