Exchange Hosted Filtering

Exchange Hosted Filtering incorporates multiple filters to actively help protect businesses' inbound and outbound e-mail from spam, viruses, phishing scams, and e-mail policy violations.

Virus Protection
Exchange Hosted Filtering helps protect organizations from all known viruses and helps provide zero-day threat protection against virus outbreaks. At the core of the service's virus-fighting strategy are multiple antivirus engines, integrated at the application programming interface level to continually provide critical virus definition updates. Exchange Hosted Filtering uses at least three different antivirus engines at all times with the ability to immediately engage additional engines when acute threats warrant additional coverage.

Spam Protection
Powered by multiple filtering engines and an around-the-clock team of anti-spam experts, Exchange Hosted Filtering virtually eliminates spam from inboxes, helping to provide bandwidth for legitimate corporate use, free precious server and storage resources, and decrease the risk of loss of sensitive information or identity theft. Captured spam is routed to the spam quarantine and can be accessed by administrators or end users at any time through an intuitive Web-based interface. An e-mail notification that lists newly quarantined spam can be configured to send to each valid e-mail address. This simplifies the end-user experience by making it simple and effective to review spam. Exchange Hosted Filtering offers the spam quarantine Web-based interface and HTML notifications in several languages.

Disaster Recovery
If the destination e-mail server becomes unavailable for any reason, Exchange Hosted Filtering helps to ensure no e-mail is lost or bounced. Exchange Hosted Filtering automatically queues e-mail for up to five days, attempting to deliver the email every 20 minutes. After the customer's e-mail servers recover, all queued e-mail is automatically delivered in a flow-controlled fashion.
