Where to find and change your work hours
Your work hours in Outlook control when you appear available to others and when the calendar shows you as working. To change them, open Outlook and go to File in the top left, then select Options. In the Options window, click Calendar on the left side. You will see a section called Work time near the top of the page.
In the Work time section, you can set your start time and end time using the dropdown menus. The default is usually 8:00 AM to 5:00 PM, Monday through Friday. Change these to match when you actually work. You can also select which days of the week count as your work days — if you work Tuesday through Saturday, uncheck Monday and check Saturday instead.
After you make your changes, click OK at the bottom of the Options window. Outlook will save your new work hours when ready. The next time someone looks at your calendar or tries to schedule a meeting with you, they will see your updated availability.
Key Takeaways
- Work hours are set through File > Options > Calendar > Work time, and you can change both the times and which days count as work days.
- Your work hours affect how Outlook displays your availability to others and which time slots show as working time on your calendar.
- Changes take effect when ready once you click OK, but others will only see the update the next time they view your calendar.
- If you work shifts that span midnight or have irregular hours, you may need to use calendar blocking or out-of-office settings instead of the standard work hours feature.
Why work hours matter in Outlook
When you set work hours, Outlook uses them to show your availability to colleagues who are scheduling meetings. Time outside your work hours appears grayed out or marked as non-working time on your calendar. This helps others avoid booking you for meetings at 6:00 PM if your work day ends at 5:00 PM.
Work hours also affect how Outlook handles meeting invitations and reminders. Some organizations use work hours to determine when notifications should arrive, and scheduling tools often respect work hours when suggesting meeting times. If your hours are wrong, the system may suggest times when you are not actually working.
Changing work hours for different time zones
If you work across multiple time zones or travel frequently, you may need to adjust your work hours to match your current location. The process is the same — go to File > Options > Calendar > Work time — but you will need to change the times each time you move to a different zone.
Outlook does not have a built-in way to set different work hours for different time zones automatically. If you regularly work in two zones, consider setting your hours to the zone where you spend most of your time, then use your calendar notes or a separate status message to indicate when you are available in the other zone.
Setting work hours when you work non-standard shifts
The work hours feature in Outlook assumes a single continuous block of time each day. If you work split shifts — for example, 6:00 AM to 10:00 AM and then 2:00 PM to 6:00 PM — the standard work hours setting will not capture that accurately. In this case, set your work hours to cover the entire span (6:00 AM to 6:00 PM) and then block off your break time on your calendar as a separate event.
For overnight shifts or work that spans midnight, the same approach works: set your work hours to cover the full range, then mark the hours you are not working as blocked time. Create a recurring calendar event for your off-hours and mark it as Busy so others see those times as unavailable.
How others see your work hours
When a colleague opens your calendar or uses the scheduling assistant to find a meeting time, they see your work hours reflected in the calendar grid. Hours outside your work time appear in a lighter shade, and hours within your work time appear in the standard color. This visual difference helps them choose times when you are actually working.
Your work hours also appear in your calendar properties if someone looks at your details. In Outlook on the web, your work hours show in your profile. On desktop Outlook, they are visible when someone views your calendar settings. The exact display depends on your organization's Outlook version and settings.
Syncing work hours across devices
If you use Outlook on multiple devices — desktop, web, and mobile — your work hours will sync across all of them once you change them. The change may take a few minutes to appear on other devices, but you do not need to set them separately on each one.
On Outlook mobile apps, you cannot change work hours directly in the app. You must change them on desktop Outlook or Outlook on the web, and the mobile app will then reflect those hours. If you are using a mobile app and do not see your updated hours, try closing and reopening the app to force a refresh.
Troubleshooting work hours that are not showing correctly
If you changed your work hours but others still see the old times, the change may not have synced yet. Wait a few minutes and ask a colleague to refresh their view of your calendar. If the problem persists, sign out of Outlook completely and sign back in to force a full sync.
If the work hours option is grayed out or missing from your Options window, your organization may have restricted this setting. Contact your IT department or help desk to ask whether you have permission to change your own work hours. Some organizations manage work hours centrally and do not allow individual changes.
Frequently Asked Questions
Can I set different work hours for different days of the week?
Yes. In the Work time section, you can check or uncheck each day individually, and you can set different start and end times for all days at once. However, Outlook does not support different times for different days — all checked days use the same hours. If you need Monday to be 9:00 AM to 5:00 PM and Tuesday to be 8:00 AM to 4:00 PM, you will need to use calendar blocking instead.
Do my work hours affect when I receive email notifications?
Work hours do not directly control email notifications in most Outlook setups. However, some organizations use work hours to determine when focus time or quiet hours should be active. Check your notification settings under File > Options > Mail > Message Handling to see whether notifications are tied to your work hours.
What happens if I do not set work hours?
Outlook will use a default of 8:00 AM to 5:00 PM, Monday through Friday. If that does not match your actual schedule, others may see you as available when you are not working. Setting your correct hours helps prevent scheduling conflicts and makes your calendar more accurate for your team.
Can I hide my work hours from others?
No. If someone has permission to view your calendar, they can see your work hours. You cannot hide them selectively. If you want to keep your schedule private, you will need to restrict who can view your calendar through your calendar sharing settings rather than hiding the work hours themselves.
Do work hours affect meeting room availability?
No. Work hours only explore to your personal calendar and availability. Meeting room calendars have their own settings and are not affected by your individual work hours. A room can be booked during your off-hours if the room itself is available.
