Mostly I'm getting sick of Google randomly dropping services I use and re-designing every 3 months.
I was looking at fastmail.fm for my mail hosting, but now I'll have to check out outlook.com as well.

Of course, the NSA revelations make it hardly matter anyway.
Microsoft helped the NSA to circumvent its encryption to address concerns that the agency would be unable to intercept web chats on the new Outlook.com portal;
The agency already had pre-encryption stage access to email on Outlook.com, including Hotmail;

If you want secure communications, you don't use email or you use something you control.
It's like saying "most regular envelopes go through the Post Office using plain vans, if you want secure communication you send it in an armoured van staffed by personally-vetted Congolese mercenaries". Nobody touches Post Office vans not because they're hard to assault (they're not), but because they're shielded with thick walls of law.
I know that smtp is more like sending postcards and yadda yadda yadda, but that's not what most legal systems have assumed for 20 years, nor what the public at large expects.
Now, knowing that MS is prone to shutting down the whole account for perceived infractions? I have family photos that aren't backed up anywhere else there. That's not cool.
Honestly, even if this policy was reserved for kiddy-porn and crack-dealers, the "boom your stuff is gone no review no discussion" approach to it means the possibility of a false-positive is scary.
IIRC, Google is just as prone to doing this too.
Get a domain, forward it to service X and Y, back it up regularly, sorted.
This applies to ALL services be they free or paid.
Saying that I've had the same hotmail/msn/live/outlook account since 1997 without a problem.
Obviously those need to be backed up. Problem solved.
The experience has been as I expected it would be: quite painful. We have not gone an entire month without service disruption. There have been problems with the service getting blacklisted. Support is, well, Microsoft support -- untimely, disconnected, uncaring, and when phones are involved very difficult to understand.
Anecdotal, sure, but according to the various forum/community postings I've come across trying to resolve various issues, not uncommon.
Caveat emptor.
edit: turns out what I was talking about (office365) and what the OP is talking about (outlook.com) aren't the same thing. Apologies.
However, we do have 500+ employees and are a large business for the country we're located in, so probably have a bit of weight when it comes to getting support.
Nice to hear you've had good experience. Perhaps I just got unlucky and my experience isn't indicative of the overall performance of the service (and maybe it'll go better for me next time).
Amusingly, our Google services were once again down this morning, making it the second disruption we've had in the month of September.
And let's not even begin to discuss the abysmal multiple account support Google has, especially surrounding their mandatory-to-join G+ nonsense.
There is no decent support. Period. Google shits on support. We all know Google has a well known disdain for support. GAE is no exception. If you cannot find help in old Google Group pages, you will not get help...
Also, here's a kicker:
Google does it's best to enforce Google+ accounts on Enterprise Accounts.
So our employees are all but forced into a PUBLIC social network for our PRIVATE accounts, and because of how much mandatory integration there is with G+, we lose a lot of Google Apps functionality without having G+ accounts. We can't even use Hangouts without a Google+ account, a requirement I found disgusting and offensive.
It sucks to hear that Office365 isn't any better because I have been nothing but let down and disgusted with Google Apps for Business.
