This is the standard configuration for Softalk Share Server. When configured as a primary store, Softalk Share Server replaces your current PST or Exchange store as the default store and optionally migrates your data into the Softalk Share Server store.

Your
folders in Outlook will look exactly as they did before, however all information
will now be stored centrally in the Softalk Share Server store database.
Personal folders for each user will be listed in the Softalk Share Server
administrator, allowing an administrator to provide access to these folders for
other users. Mail that you receive will be stored in your Softalk Share Server
store. You will also have access to any public folders that an administrator
creates and grants you access to.
