If you have mail contacts in your Exchange environment then you may want to hide them from your global address book if you are using them as forwarders.
To do this, open up Exchange Management Shell (EMS) and run the following command:
Get-MailContact -OrganizationalUnit "ADOU" | Set-MailContact -hiddenfromaddresslistsenabled $true
- “ADOU” = Organisational Unit
- $true = set all contacts to hidden (change to $false to un-hide)
This will set all the mail contacts within the stated Active Directory Organisation Unit to hidden and will not show in your global address book.
