Does Lightening for Outlook work on mobile?

Hi - We currently use a third party company called Riva to integrate Outlook items in to Salesforce. Reason we went this route is that Salesforce for Outlook at the time required Outlook to launch in order to sync. We have a sales team whose structure is Internal/External where the internals drum up meetings and calls, while the externals are in meetings all day.

We need a solution that will allow both groups to sync their meetings and emails.

Does anyone have experience w this dynamic? Users who need to sync emails and calendar items without using a computer? Salesforce of course recommends paid product, Salesforce Inbox.
