This feature is only available in Professional and Enterprise editions.
The Select Outlook and Exchange Folders dialog box allows you to select which folders Identity Finder will search. Please be patient while this dialog box opens as it will be retrieving the entire list of folders that it is possible to search. In this window you will see a list of all local Outlook folders and, if you enabled the Search Exchange Mail Server Folders option, you will also see all your folders that exist remotely on Exchange Servers or via IMAP connections.
To help you identify each folder, the Profile name, Store name, and Folder name are listed. Click the checkbox next to each Folder you want to search. If you later add folders within Outlook, they will automatically be checked and included in your next search.

For quick and easy selection of multiples folders or multiple stores, you can use the Select All and Deselect All buttons. The buttons you may use are:
For all folders in all stores in all profiles: To select or deselect every folder that you can search across all stores and profiles.
For all folders in all stores in the currently highlighted profile: To select or deselect every folder within the profile your focus is on regardless of which store they are within inside that profile.
For all folders in the currently highlighted store: To select or deselect every folder within the store your focus is on.
To view or change these settings, click the Settings button on the Tools and Options ribbon.
