Microsoft, again being arbitrary and capricious. In this case, I am an Exchange-only customer. I have no interest in Microsoft TELLING ME what clients they will allow to connect to their exchange server, and that to use their precious Exchange hosting product, I have to update all my clients, at massive cost. Easier to just move onto an alternative hosting service, one that will likely be willing to support my Office 2010 clients forever, FOREVER, until the end of time. I don't care that Office 2010 is "not supported", hell Microsoft does NOT support stuff when it is "supported.
And in this case, the notifications DID NOT HAPPEN. I woke up, had my service renew (3 days ago), and today, after paying for it, it no longer works because Microsoft decided that they want more money for clients. NOT FOR ANY OTHER REASON!!!!! All other excuses from Microsoft are just that, excuses. Now, actively looking for a new Exchange Server hosting service. Microsoft Online (Azure) completely has lost its way.
