Configuring advanced scanning options for Auto-Protect and background scanning
You can configure the additional scanning options that apply to Auto-Protect and background scanning.
To configure advanced scanning options for Auto-Protect and background scanning
In the console on the primary navigation bar, click Scans.
In the sidebar under Views, click Auto-Protect.
Under Advanced Scanning Options, check any of the following:
Scan message bodies (applies to AV only)
Detects the risks in message bodies.
The option is disabled by default.
Exclude outbound scanning on mailbox server
Prevents the scanning of outbound messages so that they can be scanned at the Hub Transport.
This option is enabled by default.
On virus definition update, force rescan before allowing access to Information Store
Performs a scan each time definitions are updated and a user attempts to access a message.
Microsoft Exchange does not allow access to any messages in the store until Mail Security re-scans the message with the latest definitions when a user attempts to access a file.
As the definitions are delivered frequently, the scan might not complete before new definitions are available. This can impact overall mail throughput.
This option is disabled by default.
If this option is selected, background scanning of the store restarts after every virus definition update. Ensure that you do not select this option if you want to complete background scanning of the entire store.
