Provides peace of mind and expands well but needs a better interface

It's a hosted solution. I'm not sure which version of the solution Im on at this time. I would advise others to research all the options out there and see what the best fit is. We started this mailbox continuity project before we moved to Office 365. And now that we've moved to Office 365, we kind of don't need this piece of technology in the same way that we used to need it when we had an on-prem exchange. Therefore, make sure that you actually need it and then research to find the best options. Overall, I would rate the solution seven out of ten.

Works

This is a dud product with inferior spam filtering

This is a dud product with inferior spam filtering versus alternatives like SpamHero, and the continuity feature is essentially marketing fluff. Failed deliveries, for example, they don't count it as an issue so those messages won't be queued for another delivery attempt. As I understand it from talking to their support, if the server pings or sends any response at all, then Mail Assure will not keep a copy. It will also weirdly mark messages during that outage as rejected, so it's not like Mail Assure doesn't know that the message never reached the user(s).
