A positional parameter cannot be found that accepts argument

Hi,@Rising Flight

Thanks for posting your question in the Microsoft Q&A forum.

The error message suggests that there is a problem with the syntax of your Select-Object command. The issue might be with the way you're specifying the properties to select, especially since you have a space in 'extension attribute01'. PowerShell might be interpreting 'extension attribute01' as two separate arguments rather than one property name.

Here is how you can modify your command:

Get-DistributionGroupMember -Resultsize Unlimited 

Here is my test, the command works fine.
