To test this critical aspect of hosting, we include uptime monitoring as part of our review process, and the results show that most web hosts do an excellent job of keeping sites up and running. Sites with uptime problems aren't eligible for high scores, no matter how good the rest of their offering may be. All services suffer ups and downs, sometimes for reasons beyond their control. Those sites that fail to quickly address the problem are penalized accordingly.
For email, security starts with spam, otherwise known as unsolicited email. This is often the bane of not only those who live in their email inboxes,but also of the IT administrators who manage email services. The good news is that spam filters are getting better every day and email providers tend to deploy the very latest and greatest for their customers. The bad news is that these filters still aren't perfect, which means they can catch a lot of "good" email but often vary significantly in effectiveness. Today's spam filters are based largely on machine learning (ML) as the primary method of determining what's bound for the trash bin. Given that ML gets more effective over time, it is no surprise that the services that have been around the longest tend to have better spam detection.
Along with the slew of desktop apps, you also get access to Microsoft Outlook Web Access (OWA), a sleek and modern web adaptation of the Outlook email client. It offers a familiar layout for calendars, contacts, and tasks, and a new "focused inbox"—all available in your browser. What Microsoft means by a "focused inbox" is that, rather than just being a dumping ground for all incoming email, it defaults to a dynamic view that's constantly being updated. This tech is based on a machine learning (ML) algorithm that attempts to figure out which email is most important to you; everything else goes to the regular inbox. As you sort emails between the focused inbox and the regular inbox, the algorithm gradually gets better, helping you to concentrate on email that matters most. You'll also be able to use mentions. When creating a new email, if you prepend someone's name with the @ sign, then it will automatically Cc that individual. You can also apply a filter that will show you emails in which you were directly mentioned.
