Reviews are right - fundamental UX design rules are ignored (scrolling and navigation). Even if that were fixed, DynamicsCRM itself is ugly - font size isn't consistent and there are no preference settings, when you click into any of the options there is a colored block covering the first letter (e.g, Accounts, Contacts), which I think they believe is clever, and most annoying of all it doesn't always keep you logged in like countless other apps are able to do. No executive will remember what their login credentials are nor will they want to bother with doing so after the initial login. The major barrier to utilization of CRM by our entire org is due to a lack of mobile access. I was hoping DynamicsCRM would solve for that, but it really falls short and needs either a major overhaul or several iterations of releases.
