The application performs a background scan of mailbox repositories and shared folders that have been marked in the Protected mailbox storages and Protected public folder storages lists. Before running a background scan, select repositories that must be scanned, and save the changes.
To run a background scan manually:
The stop button is displayed during the background scan.
If the selected Security Server is running on a Microsoft Exchange 2013 or Microsoft Exchange 2016 server, the progress bar and the background scan stages (Preparing for scan, Step 1 of 2. Scanning mailboxes, Step 2 of 2. Scanning shared folders) are also displayed during the background scan. When the operation is complete, the application displays a scan report (completion time, number of mailboxes and shared folders scanned).
The background scan start and stop actually occur within a minute after the Start scan/Stop button is clicked.
