As you add information to your system, the domain databases (wpdomain.db) and post office databases (wphost.db) increase in size. If you delete information, the space created in the databases for the information is not immediately recovered. GroupWise uses the free space before requiring more disk space; however, if you have deleted a large amount of information, you might want to reclaim unused database space. If you have frequent changes to your users, especially deletions, you should occasionally reclaim disk space.
In the GroupWise Admin console, browse to and click the name of the domain or post office where you want to reclaim disk space.
For a domain, click Maintenance.
or
For a post office, click Maintenance > Post Office Database.
Select Reclaim Unused Space.
Click Run.
