Allow follow up emails to meeting attendees to be sorted by response
We have a recurring "meeting" (workplace welfare/workout), which hasn't mandatory attendance, and relies on enough people showing up for the activity to take place.
People who have responded, and declined, usually don't want any follow up emails or more nagging about the activity. People who've responded they're either attending or tentative, wants a status update either the day before or the same day of the activity. In addition, to ensure attendance enough to have the activity, there's a need to contact just those who've not responded.
The Office 2016 Outlook client, has no way (that I can find) that allows to differentiate communication between these three groups, and it would have been nice to be able to send emails/follow ups according to their response - not having to manually delete recipients in a semi-colon separated address field, or as I've done some times first export the attendee tracking to Excel, format as table, sort, and copy names back to Outlook.
