Control and/or set default email, contacts, calendar accounts
An issue I often see with mobile devices is that the user doesn't realize which calendar they've selected for creating an event. They think it is the corporate calendar, maybe don't use any other calendar on the mobile device. They open the calendar, create an event, send it to work associates. The people they send the event to accept, and are made aware of the meeting. But the sender has unknowingly created this event on another calendar (maybe the icloud calendar) So on their PC Outlook does not get the event. Everyone else makes it to the meeting but they miss it because they did not get alerted by Outlook.
If we can set the default account for email, contacts, calendar we can prevent this from occurring.
It would be good to have the option of setting the default account or controlling the default account so it could not be set differently.
