Just found an interesting example of PowerShell reducing the number of helpdesk calls (at least from me).
Our office IT sent out an email to everyone in my office telling that the appropriate procedure to get personal details (such as phone numbers) updated in the GAL is by sending email to the helpdesk alias.
I asked them whether this was because AD was not authoritative. It turned out that for this information it is indeed authoritative so what they do once they get an email request is actually changing the attributes in Active Directory.
My reply of course was that in this case I didn’t need the helpdesk and PowerShell did the job for me just fine.
Here’s the screenshot which I attached to the email:
This of course is possible because PowerShell is not just for admins!
