Use the Shell to update a GAL

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Global address lists" entry in the Mailbox Permissions topic.


You can't use the EMC to update a GAL.

To update a GAL, use the following syntax.

Update-GlobalAddressList -Identity <GlobalAddressListIdParameter> -DomainController


Running this command only starts the update process. It may take several hours for the GAL to be updated.

This example updates a GAL for the Fourth Coffee company.

Update-GlobalAddressList -Identity "Fourth Coffee"

For detailed syntax and parameter information, see Update-GlobalAddressList.
