|
• | Hours — Select this to schedule the task based on hours, if you have to execute the on-demand scan task for more than once in a day. For example, let's consider that the current time is 14:00 hours and you have to create an on-demand scan task that satisfies these conditions:
◦ | The on-demand scan must start exactly at 14:30 hours
|
◦ | The on-demand scan must occur twice a day
|
To achieve this, specify
12 for hours and
30 for minutes.

Restart from last item options to run the on-demand scan task in multiple sessions on mailbox database.
| Sometimes, you might want to run an on-demand scan task for all mailboxes. Scanning all mailboxes in one session might take longer time and that can affect the system's productivity. Instead of scanning all mailboxes in one session, you can schedule the scan for multiple sessions.

On Exchange Server, you now have the option to perform a granular on-demand scan task. You can narrow down the scan using these fields:
• | Subject
| • | Date range
|
• | From
| • | Mail size
|
• | To
| • | Attachments
|
• | Message ID
| • | Unread items
|
• | Recipients

Performing a granular on-demand scan saves you time and fetches specific scan results.
