Scheduling preferences used by Scheduler

Scheduler uses several Outlook preferences to schedule a meeting for an organizer. Any changes to the preference settings in Outlook clients will affect how Scheduler handles requests sent to Cortana. For instance, if an organizer changes the time zone preference on the settings page in Outlook Web, all requests by the organizer that follow will default to the new time zone.

Supported settings

  • Time zone. The time zone Scheduler uses to determine an appropriate time for meetings. See Add, remove, or change time zones for information.

  • Work hours and days. For most meeting types, Scheduler selects a time according to the organizer's work week and meeting hours preferences. See Change your work hours and days in Outlook for information.

  • Online meetings. You can turn on a Calendar option so that all the meetings you schedule from Outlook and Scheduler will be held online with conference details. Scheduler currently supports Teams and Skype as meeting providers. See Make all meetings Teams meetings for information.

  • Default meeting duration. If the organizer doesn't specify the desired meeting duration in the request, Scheduler will use the preferred meeting duration for the request. This setting is only available in the Windows Outlook client.
