An Exchange mailbox. (You can typically create a mailbox at the same time as you create a new user account in Active Directory.)
Read access to Exchange Public Folders for the limited access user.
Read and Write access to Exchange Public Folders for the full access user. This permits the FSA to copy or delete Public Folder items.
The FSA also requires a default email application compatible with Microsoft Exchange, such as Microsoft Outlook.
Microsoft SharePoint sites, the FSA Run As user must be a domain user with local administrator rights on the SharePoint host machine and must be a member of the MSSQL db_owner role on the SharePoint configuration database and any SharePoint content databases that contain the site data being scanned.
