- Product
- Microsoft 365 Calendar
- Device & OS
- not provided
- Scenario
- Scheduling recurring calendar events for weekends (Saturday and Sunday).
- Observed behavior
- Recurring weekend events do not behave as expected, and the calendar desynchronization is accompanied by broader email delivery or account management issues.
Ensure you have administrator access to the Microsoft 365 admin center to submit service requests, and verify that your system time zone is correctly configured.
Verify Recurrence Settings in Outlook
Check and re-configure your event recurrence settings across both web and desktop versions to ensure synchronization and correct day selection.
Desynchronization between Outlook on the web and the desktop client can cause recurring events to display incorrectly. Verifying the specific days and time zone settings can often resolve client-side glitches.
Launch the Outlook desktop application or log into Outlook on the web, then navigate to your Calendar view.
Double-click the problematic recurring weekend event and select the option to edit the entire series, not just a single occurrence.
Click on 'Recurrence' and verify that both 'Saturday' and 'Sunday' are explicitly checked under the weekly recurrence pattern.
Check the event time zone to ensure it matches your current local time, as mismatches can push weekend events to weekdays.
Save your changes and refresh the calendar to monitor if the weekend events populate correctly.

Submit a Service Request for Tenant Issues
If calendar issues are accompanied by email or account problems, submit a backend investigation request to Microsoft Support.

Frequently Asked Questions
Why are my recurring weekend calendar events not showing up in Outlook?
This can occur due to desynchronization between Outlook on the web and the desktop client, incorrect recurrence pattern settings where Saturday and Sunday aren't explicitly selected, or broader tenant issues affecting the Microsoft 365 back end.
Does the time zone affect recurring calendar events in Microsoft 365?
Yes, if the calendar's time zone does not match your local time zone, events (especially those near midnight) may span across different days or fail to appear on the intended weekend dates.
Who can submit a service request in the Microsoft 365 admin center?
Only users with administrative privileges, such as Global Administrators or Support Administrators, can submit backend service requests on behalf of the organization's tenant.
