How so? Are you turning the phone on? The problem with Android is, when the phone gets older the manufacturer will cut support. All Nokia windows phones have had every single GDR update and they're all set to receive 8.1
Have you looked into OS10 and the newer Blackberry's? It's a fantastic phone, more so now considering the price (under £200 per handset).
Just doing this now and we have chosen Windows phones.
Couple of reasons.
They work well with Exchange and Office as mentioned above.
Enough apps for our needs, but not so much rubbish that users will just fill the phones up.
Seems to be inherently more secure than Android as OS is (currently) locked down, not easy to fiddle with.
Standard look across models. Every Windows phone is virtually identical to use, without the issues of different skins on different Android phones.
The budget Android phones we bought (HTC Wildfires) were a complete disaster and put me off wanting to support Android users in the future.

Only issue I have experienced is the desktop software is utterly horrendous on windows phone.
Super basic.
But I guess everything is cloud based.
What do you mean? You just open file explorer and put your files on that way?
And if you get a Nexus device you won't loose support because it's supported directly by Google. Although I wouldn't recommend the N5 as you likely wouldn't be able to use the camera as it's dreadful.
There's nothing wrong with the N5 camera.There's so much wrong with my W8 phone, but for starters;
No drop box
No decent browsers
No VPN
Lync is pap
Email client is pap
Calendar client is pap
Bing
Fails to recognise most documents as being openable
Doesn't search your address book as you type a phone number
Difficult to join meetings from calendar entries (doesn't highlight phone numbers)
General unintuitive UI for most things
Keyboard doesn't scale in landscape
Can't change the keyboard
Send button right next to enter, I'm forever sending half written emails
Random screen freezes and unresponsiveness
Yes they are little things, but they add up and annoy meal much I wish I had got something else. W8 lacks even basic customization and useability. Dropbox and VPN are the killers. What my company doesn't store on Dropbox is stored within the network requiring VPN. There are things I simply can't do for my job on my work phone.
On the plus side the battery is fantastic and its a really nice solid yet simple phone to hold and use (Nokia Lumia 620).
