When you work a hybrid schedule, your in-office days and remote days often have different start and end times. Outlook lets you set different working hours for each day of the week, so your calendar accurately reflects when you are available. This feature also controls the default meeting start times and the shading that shows your working time in the calendar view. In this article, you will learn how to configure per-day working hours, how to apply the settings across multiple devices, and what to do when the changes do not take effect immediately.
Key Takeaways: Per-Day Working Hours in Outlook
- File > Options > Calendar > Work Time: The main location where you set different start and end times for each weekday.
- First day of week / First week of year: These settings affect how the working hours grid aligns with your calendar view.
- Sync with Exchange or Microsoft 365: Per-day working hours sync automatically to all devices signed into the same work or school account.
Understanding Outlook’s Per-Day Working Hours Feature
Outlook has supported setting different working hours for each weekday since Outlook 2016. The feature lives in the Calendar options and applies to the primary calendar of your Exchange or Microsoft 365 account. When you change the working hours for a specific day, Outlook updates the shaded area in the weekly and daily calendar views. Meeting requests sent to you will be scheduled within those blocks if the sender checks your free/busy information. The setting also controls the default duration for new appointments and meetings created on that day.
Before you configure per-day hours, confirm that you are using an Exchange, Microsoft 365, or Outlook.com account. POP and IMAP accounts do not support per-day working hours because they lack the server-side free/busy publishing that makes this feature work. If you manage multiple calendars, only the primary calendar for your work or school account receives the per-day shading. Shared or secondary calendars use the default working hours you set for the primary account.
Steps to Set Different Working Hours for Each Day
The following steps apply to Outlook for Microsoft 365, Outlook 2021, Outlook 2019, and Outlook 2016. The menu paths are identical across these versions.
- Open Calendar Options
Open Outlook and click File in the top-left corner. Click Options in the left navigation pane. In the Outlook Options dialog, click Calendar in the left column. - Locate the Work Time Section
Scroll to the Work time section. You will see a table with rows for each day of the week. Each row has two drop-down menus: one for start time and one for end time. - Set Start and End Times Per Day
Click the start time drop-down for Monday and select your in-office start time, for example 8:00 AM. Click the end time drop-down and select 5:00 PM. Repeat this for Tuesday through Friday. For a hybrid schedule, set different times for your remote days. For example, set Wednesday to 9:00 AM to 6:00 PM if you start later on that day. - Set the First Day of Week and First Week of Year
In the same Work time section, set First day of week to Monday (or your preferred start day). Set First week of year to the option that matches your organization’s fiscal calendar. These settings control how the working hours grid aligns with your calendar view. - Apply and Verify
Click OK to close the Outlook Options dialog. Switch to your calendar by clicking the Calendar icon in the bottom-left corner. Change the view to Work Week or Week on the Home tab. The shaded area for each day should now reflect the times you set.
Set Working Hours for Saturday or Sunday
If your hybrid schedule includes weekend work, you can enable Saturday and Sunday in the Work time table. In the same Work time section, check the boxes for Saturday and Sunday if they are not visible. Then set the start and end times for those days. Unchecking a day removes it from the working hours grid entirely.
Common Issues and Workarounds
Per-Day Working Hours Not Showing in Calendar View
If the shaded area in your calendar does not match the times you set, first check that you are viewing the correct calendar. Click the calendar name in the left navigation pane to ensure the primary calendar is selected. Next, confirm that the view is set to Work Week or Week. The Day view also respects per-day hours, but the Month view does not show shading. If the view is correct, close and reopen Outlook. The settings apply immediately but the calendar view may need a refresh.
Changes Not Syncing to Outlook Mobile or Outlook on the Web
Per-day working hours are stored on the Exchange server or Microsoft 365. They sync automatically to Outlook on the web and to Outlook mobile apps that use the same account. If the changes do not appear, sign out of the app and sign in again. On mobile, go to Settings > Calendar > Working Hours and verify that the times match what you set in the desktop client. If they still differ, check that your account type is Exchange or Microsoft 365.
Meeting Requests Still Arrive Outside of Working Hours
Setting per-day working hours does not block meeting requests. It only controls the shading in your calendar and the free/busy information that senders see. If a sender ignores your free/busy data, the meeting request will still arrive. To prevent this, set your Outlook calendar to automatically decline meetings outside of working hours. Go to File > Options > Calendar and scroll to Automatic accept or decline. Click Automatically accept or decline meeting requests and then set the rules to decline meetings that fall outside your working hours.
Per-Day Working Hours vs Default Working Hours: Key Differences
| Item | Per-Day Working Hours | Default Working Hours |
|---|---|---|
| Configuration location | File > Options > Calendar > Work time table | File > Options > Calendar > Work time (single start/end) |
| Number of schedules | Up to 7 different schedules, one per day | One schedule applied to all weekdays |
| Calendar shading | Shaded area differs per day | Shaded area is identical for all weekdays |
| Free/busy publishing | Publishes different times per day to meeting senders | Publishes the same times for every weekday |
| Supported account types | Exchange, Microsoft 365, Outlook.com | All account types including POP and IMAP |
| Sync across devices | Syncs automatically via Exchange or Microsoft 365 | Syncs only if account is Exchange or Microsoft 365 |
Conclusion
You can now set Outlook to show different working hours for each day of the week, making your hybrid schedule clear to colleagues and meeting senders. The settings sync across your desktop, web, and mobile Outlook clients automatically. To further refine your calendar, try enabling automatic decline of meetings outside your per-day hours. This gives you full control over your availability without manual updates each day.
