Microsoft Updates Exchange Online Protection to Battle Holiday Spam
The company issued an update intended to help organizations deal with inboxes that are beginning to fill up with not-so-glad tidings.'Tis the season for more spam. With the holidays approaching, Microsoft is currently rolling out an update for its Exchange Online Protection (EOP) service that is meant to help users deal with the onslaught of email promotions and cut down on the inbox clutter. EOP is a cloud-based enterprise email security product that filters spam and malware. Microsoft claims that EOP helps block 10 million spam messages per minute for the company's customers. The new EOP update provides organizations with new tools to filter bulk emails. "With this new capability, we are introducing a simple, intuitive control in the Exchange Admin Center to allow you to easily block more of these 'bulk' emails," wrote Microsoft Exchange Online Protection program manager Chris Nguyen and technical product manager Shobhit Sahay in a Nov. 24 blog post. Microsoft classifies bulk email as "email that falls somewhere in the middle of spectrum between junk email and good email—some users want it, others do not," said Nguyen and Sahay. "Examples of bulk email include newsletters, social updates and promotions," content that may not be entirely unwelcome, but can nonetheless compete with legitimate work emails for attention.
Since the difference between bulk email and outright spam is not cut-and-dried, Microsoft is relying on a measurement called Bulk Complaint Level. "Earlier this year, we significantly increased EOP's bulk detection and assigned Bulk Complaint Level (BCL) ratings to email from bulk senders to indicate the likelihood it would generate a complaint," explained the bloggers.
