Scheduling and managing events using Outlook.com calendar
There is no setting in the provided Outlook on the web or Outlook.com calendar guidance to suppress reminders specifically for meeting requests that are still Tentative or not yet accepted.
What is supported:
- To stop reminders for a specific meeting or series in Outlook on the web, open the event in Calendar, then use Reminder and select Don’t remind me.
- To reduce reminders for all events, go to Settings > Calendar > Events and invitations and change Default reminder.
- If meeting requests are being added automatically, Automatic processing settings control how invitations and notifications are handled, including deleting outdated invitations/responses and forwarded event notifications, but the provided settings do not include a per-status reminder option for unaccepted meetings.
