Exchange 2013 Hide MailContacts From The GAL

Back in Exchange 2010 you could use the Exchange Management Console (EMC) to hide any type of recipient from the GAL.
Unfortunately for admins who only use the Exchange Admin Console (EAC) you can't do that anymore in Exchange 2013; you have to use the Exchange Management Shell (EMS).

You can still hide MailUsers in the EAC, but not Contacts, which is strange. Yes I'm talking to you, Microsoft...

Luckily, it's a simple cmdlet to hide Contacts.

Fire up the EMS, and run:

Set-MailContact "alias" -HiddenFromAddressListsEnabled $true

**Note** Change "alias" to the MailContact name you're working with.

Now, that contact is hidden and you can check with this cmdlet:

Get-MailContact "alias" | fl *hidden*

**Note** Again, change"alias"
