Disabling a post office restricts users from starting the GroupWise Windows client and accessing the post office. However, users who are already running the GroupWise client can continue to access the post office; after they exit, they cannot access the post office again until the post office is enabled.
A post office must be disabled if you are rebuilding the post office database (wphost.db). You might also want to disable a post office when you are doing a complete GroupWise system backup. That ensures that all data is consistent at the time of the backup.
In ConsoleOne, browse to and right-click the Post Office object, then click.
Click> to display the Client Access Settings page.
Select, then click to disable the post office.
(Conditional) To re-enable logins and make the post office available again, deselect.
