Discontinuation of support for Session Border Controllers in Exchange Online Unified Messaging

I didnt realize that Microsoft had become the biggest Ransomware threat on my network.  I'm sure we'll have to true up next year with a bitcoin account.  Thank you Microsoft for proving that you really do not care about your customer base or the large time and money investments they have made in order to make your product fit within their business. Not only is this going to cost us a large amount of money to transition to our 3rd party VM software, we only have 1 year to figure out how to make it happen.  In addition, all of the time and money we have spent on redundant session border controllers over the last couple of years are now going to become worthless. This is completely unacceptable.
