Yea i am thinking of moving to a hosted exchange by MSFT. I had it for a while i did not find it very reliable sadly. I set a client up with hosted rack space it is flawless the cost is just to much for a personal account 10 a month ouch.
Honestly, consider checking out O365 again - the platform has improved significantly in the past 12 months, moreso in the past 3 months as they cut out some of the older cruft as service support periods end. One can also find the Personal and 5-install Home licenses on Amazon at about a 25% discount with very little hunting ($44/$74, respectively), and sometimes you'll find someone selling a license here in MR's Marketplace - and I've seen for myself that the Personal version can be upgraded for $9.99 to the Home version (if you get a free or cheap Personal license and want more installs).
What hasn't been publicized much is that MS announced several weeks ago that they're moving the Outlook.com platform to the same platform that drives O365 - I posted a link in one of my posts here some time ago but don't have it handy. I've got an Outlook.com account for my Win10 install, and have seen my calendar events, emails, and contact data "matched" in real time between the web interface, Outlook 2013, the Windows app clients, and my iPad/iPhone - with no cost and real alias support now for Outlook.com it's a no-brainer - as a Mac user going back to 1988, I can finally offer that I like what MS is doing with this.
I'm planning to get one of MS's "Business Premium" accounts so I can get the 5-install license, my own branded email, lots of other services including UL storage space (my current Home account has a 10TB "limit" now
), and better CS, for $100 at Amazon - less than $9 per month. I've been reading over time that Google is cutting/restricting/ending this service or that service while MS is offering more services as time goes on - Google sells ads, and MS sells services. Keep in mind that you can also get a free 30-day trial too. I demoed Rackspace for my small business but had too many sync and outages, but I never dissuade anyone from trying or keeping a paid service as I know what works for me - besides, we have offices in Seattle and Portland - MS has servers within 10 miles or so of us, and that's hard to beat! Cheers!
