I'm getting an alert msg that my Outlook (ver 2.48.0) is out of date, I'm running iOS 9.3.4, is there something I can do about it other than updating my iOS? I'm afraid to update the iOS cause I have an iPhone 6s+ 
Might I have issues running this old Outlook version?
Can I just ignore the msg I'm receiving?
