Choose the Outlook Profile needed if set to prompt otherwise if there is only one profile it will load that one by default. 5. Double-click the Default Store for the user's mailbox. Note: if there are multiple entries then there could be several Personal Folder Files represented and you should see the Mailbox Store on the Server as well as Public Folders on the Server.
