Microsoft has added the Manitoba Standard Time time zone to Windows and Microsoft 365. If your organization has moved to the new Manitoba time zone, both Windows and Outlook should be checked to ensure your computer and calendar use the correct time zone.

This is especially important for Outlook calendars because existing appointments and recurring meetings may have been created using Central Standard Time and may need to be reviewed.

1. Check the Windows time zone

1. Right-click the date and time in the bottom-right corner of the Windows taskbar.
2. Select Adjust date and time.
3. Under Time zone, confirm that the time zone is set to Manitoba Standard Time.
4. Confirm that the date and current local time displayed by Windows are correct.

If Manitoba Standard Time is not available:
Your computer may be missing the Windows update that adds the new Manitoba time zone. Install available Windows updates and restart the computer.

If the option is still unavailable after updating and restarting, contact Mennotech Support.

New Outlook and Outlook on the web

Important: Changing the Windows time zone does not mean you should assume that every Outlook calendar setting or existing calendar item has been updated. Check Outlook separately.

3. Check Outlook work hours and location

While in Outlook Settings:

1. Go to Calendar > Work hours and location.
2. Confirm that your normal work days are correct.
3. Confirm your normal start and end times.
4. Check the time zone shown for your work hours and confirm it reflects Manitoba Standard Time.
5. Select Save if you make changes.

Correct work hours are particularly useful when other people are scheduling meetings with you using Microsoft 365.

4. Review upcoming appointments and meetings

After changing time zones, review your upcoming Outlook calendar.

Pay particular attention to:

• Recurring meetings
• Recurring appointments
• Meetings scheduled well in advance
• All-day events
• Calendar items where the displayed time no longer looks correct

If an item occurs at the expected Manitoba local time, no action is required.

Correct an appointment or meeting

If an Outlook calendar item is showing the wrong time:

1. Open the calendar item.
2. Select Edit.
3. Display the Time zones option if it is not already visible.
4. Select Manitoba Standard Time.
5. Confirm that the start and end times represent the intended local time.
6. Select Save for an appointment, or Send / Send update for a meeting with attendees.

For a recurring item, carefully confirm whether you are editing a single occurrence or the entire series. If the entire recurring series is affected, update the series.

5. If Manitoba Standard Time is missing

If Manitoba Standard Time does not appear as an available Windows time zone:

1. Open Settings > Windows Update.
2. Check for available updates.
3. Install applicable Windows updates.
4. Restart the computer.
5. Check the time-zone setting again.

If Manitoba Standard Time is still unavailable, or if the computer displays an incorrect local time after selecting it, contact Mennotech Support.

When contacting support, please include:

• Whether Manitoba Standard Time appears in Windows
• Whether Windows is displaying the correct local time
• Whether the problem is also occurring in Outlook for all items or specific items
• Please provide screenshots showing the issue (WIN + SHIFT + S)

Summary

After the Manitoba time-zone change, verify these three areas:

1. Windows: Time zone is Manitoba Standard Time.
2. Outlook: Calendar and work-hours settings reflect the Manitoba time zone.
3. Calendar: Upcoming and recurring meetings occur at their intended local times.
