The application runs an on-demand scan of those mailboxes and shared folders that are specified in the Scan scope field.
To configure and run an on-demand scan:
In a configuration with a Microsoft Exchange 2013 or Microsoft Exchange 2016 server, the application runs an on-demand scan of messages and other Microsoft Exchange objects that were modified (including those received) during the specified number of days before the start of the on-demand scan.
Maximum parameter value is 364 days.
The maximum value of this setting is 168 hours.
In a configuration using a Microsoft Exchange 2010 server, the application does not generate a list of shared folders. On-demand scan in shared folders is not available.
The stop button is displayed while an on-demand scan is running.
An indicator of the progress and stages of scan completion is displayed while an on-demand scan is running (Preparing for scan, Step 1 of 2. Scanning mailboxes, Step 2 of 2. Scanning shared folders). When the operation is complete, the application displays a scan report (completion time, number of mailboxes and shared folders scanned, and number of infected messages in mailboxes and shared folders).
The on-demand scan start and stop actually occur within a minute after the Start scan/Stop button is clicked.
