Similar to the Outlook desktop app or Outlook on the web, you can view your colleagues’ availability and select the best meeting time. In the Outlook mobile app, create an event from your calendar and add your coworkers to the People field, then you’ll see an indicator of attendee availability on the date picker. Outlook will let you know right away if the time works for everyone. To find an alternate time, just drag and drop the event until it turns green indicating everyone is available at that time. You can also track the RSVPs for your meetings—green check marks indicate they’ve accepted, red X’s indicate they’ve declined, and grey question marks indicate they haven’t responded yet.
