Notifications
Schedules can notify assigned Microsoft 365 users when their appointments are created, updated or deleted. These are appointment-change messages, not timed reminders before an appointment starts. They are not broadcasts to everyone who can view the schedule.
Teams notifications
An administrator opens Settings > Notifications and enables or disables Teams notifications. When enabled, assigned users other than the person making the change can receive a Teams activity notification. Check the Teams activity feed and your Teams notification settings.
Assignment emails
Email delivery requires both:
- An administrator enabling assignment emails under Settings > Notifications.
- The recipient enabling assignment emails under My Settings.
Recipients must be resolvable Microsoft 365 users with an email address. Manual planning entries are not notification accounts. As with Teams notifications, the person making the change is excluded.
Several changes can be grouped into one email. Delivery is queued and can be delayed; do not expect one immediate email per edit or use these emails as a time-critical alert.
Test delivery
Use two different accounts. Assign a test appointment to your colleague and change it from your own account. Have them check Teams activity and email, including junk/quarantine, and allow time for batched email delivery. Changing an appointment assigned only to yourself is not a delivery test.
If nothing arrives, check:
- The appointment's assignees are the intended directory users, not duplicate manual entries.
- Both people are working in the same schedule scope.
- The relevant administrator switch is enabled; for email, the recipient has not opted out.
- The work account has a valid email address and organization policies allow delivery.
- Teams notifications are not muted; email is not blocked or quarantined.
If the checks pass, contact Support with the approximate time, schedule scope and channel (Teams/email) that failed. Do not include access tokens or calendar subscription URLs.
