How to change interface in ootlook web app?

Question

Outlook

We have Microsoft Exchange 2013.
When you try to open OWA, an interface similar to Microsoft outlook opens.
When you work from a computer, there are no problems. But when you open from a mobile device (apple for example) - then there are always some problems. Either the buttons are not clickable, or the letter cannot be viewed, etc.
If you open it on Android through a standard browser (not chrome), then a simple interface opens, and so it works fine!
What you want.
1. Can you tell me if this OWA can be fixed so that there are no problems on mobile devices
or
2. How can I make a simple interface open on all mobile devices? (light) by default

Answer 1

A non-standard task is not solved in standard ways) You need to seriously approach the issue and do it, and do it ...
The standard solution for mobile devices is to publish ActiveSync.
Then everything will be beautiful, inside the mobile interface of a specific mobile platform, using standard methods.
