Suggestion for new phone primarily for email on exchange

getting a new phone soon because my ooold droid i think running android 2.3 or 4.2 just doesn't want to work 

I use outlook for work and wondering if i should switch to a windows phone 

im on verizon any suggestions would be help full  

We use Microsoft exchange 2013 where I work, I was issued a Verizon iPhone 5C to access my e-mail, it works fine for all basic e-mail functions. Are you looking to use the more advanced Exchange functions from your phone?

not really *nothing security related - I like all the folders and priority stuff calendar with outlook - considering I have to buy this phone out of contract since my monthly fee will double if I move from unlimited data on Verizon I'm just trying to do my homework or maybe switch carriers
