Notify co-workers about running late to a meeting
Flow button for mobile
Office 365 Outlook, Approvals, and Notifications
If you're going to be late to a meeting, tap this button flow. It will send you an approval notification telling you who is at your next meeting. Approving will email all of those people that you'll be late, or, rejecting will do nothing. You can even provide comments in the approval, and they will be included in the email.
