Top blog posts from 2015


It’s the last day of 2015 and I thought it would be interesting to look back on the top blog posts of this year. When thinking about this past year, the first topic that comes to mind is Spoofing/Phishing, and anti-spoofing technologies like SPF, DMARC, and DKIM. These types of attacks continue to be heavily used in the messaging world. From a feature perspective, we introduced Exchange Online Advanced Threat Protection, in addition to enabling support for DKIM signing on outbound mail. It’s been a busy year, and I’m sure 2016 will be even busier.

Here are the top posts from this blog for the last couple of years.
