Where to find the time zone setting in Outlook

The time zone setting in Outlook lives in your calendar preferences, not in a general settings menu. The exact location depends on which version you use — Outlook on the web, Outlook for Windows, or Outlook for Mac each keep this setting in a different place. The steps below cover the most common versions.

Your time zone setting affects how Outlook displays meeting times, when it sends meeting invitations to others, and how it calculates reminders. If you travel or move, changing this setting ensures your calendar shows the correct local time and that meeting invitations reflect your actual availability.

Key Takeaways

  • In Outlook on the web, go to Settings > Calendar > Time zone and select your location from the dropdown menu.
  • In Outlook for Windows, open File > Options > Calendar and change the Time zone field under Calendar options.
  • In Outlook for Mac, select Outlook > Preferences > Calendar and choose your time zone from the list.
  • Changing your time zone does not move existing meetings — it only changes how Outlook displays them going forward.
  • If you work across multiple time zones, you can display a second time zone on your calendar without changing your primary setting.

Changing time zone in Outlook on the web

Open Outlook in your web browser and select the gear icon in the top right corner. From the dropdown menu, click View all Outlook settings. In the left sidebar, select Calendar, then click Time zone.

A dropdown menu will show your current time zone and a list of all available zones. Type the name of your city or region to filter the list — for example, typing "Denver" will show Mountain Time options. Select your time zone and the page saves automatically. Your calendar will update within a few seconds.

Changing time zone in Outlook for Windows

Open Outlook and select File in the top left corner. Click Options at the bottom of the menu. In the Outlook Options window, select Calendar from the left sidebar.

Under the Calendar options section, find the field labeled Time zone. Click the dropdown and select your time zone from the list. You can also type to search — typing "Chicago" will jump to Central Time zones. Click OK at the bottom of the window to save your change.

Changing time zone in Outlook for Mac

Open Outlook and select Outlook in the menu bar at the top of the screen. Click Preferences. In the Preferences window, select Calendar from the list on the left.

In the Calendar preferences pane, find the Time zone dropdown. Select your location from the list. The change takes effect when ready. Close the Preferences window when you are done.

What happens to existing meetings when you change time zones

Changing your time zone does not move or reschedule existing meetings. Instead, Outlook recalculates how it displays those meetings in your local time. If a meeting was scheduled for 2:00 PM Eastern Time and you change to Pacific Time, Outlook will show it as 11:00 AM — the same meeting, just displayed in your new time zone.

This can be confusing if you do not expect it. The meeting invitation you sent to others still shows the time you originally sent it in, so they will not see a change. Only your calendar display changes. If you need to reschedule a meeting to a different actual time, you must send an updated invitation.

Displaying a second time zone without changing your primary setting

If you work with people in another time zone regularly, you can show a second time zone on your calendar without changing your primary setting. In Outlook on the web, go to Settings > Calendar > Time zones and toggle Show a second time zone on. Select the second time zone from the dropdown below.

In Outlook for Windows, open File > Options > Calendar and check the box next to Show a second time zone. Type or select the time zone you want to display. In Outlook for Mac, go to Outlook > Preferences > Calendar and check Show a second time zone, then select it from the dropdown. Your calendar will now display both time zones side by side, making it easier to schedule across regions.

Troubleshooting time zone changes that do not take effect

If you change your time zone and your calendar does not update, try closing and reopening Outlook completely. Sometimes the process needs to refresh to display the new setting. If you use Outlook on the web, try clearing your browser cache or opening Outlook in a private or incognito window to rule out cached data.

If you are using Outlook for Windows and the change does not stick, check that you clicked OK at the bottom of the Options window — clicking elsewhere or closing the window without saving will discard your change. For Outlook for Mac, make sure you closed the Preferences window properly. If the problem persists across multiple attempts, sign out of Outlook completely, wait a few minutes, and sign back in.

Frequently Asked Questions

Will changing my time zone affect meetings I have already scheduled?

No. Changing your time zone only changes how Outlook displays existing meetings in your calendar. The actual meeting time does not move, and other attendees will not see any change. If you need to move a meeting to a different time, you must send a new invitation.

What if I travel and need to change my time zone temporarily?

You can change your time zone in Outlook at any time. When you return home, change it back. If you travel frequently between the same two zones, use the second time zone display feature instead — it lets you see both zones without changing your primary setting.

Does changing my time zone in Outlook affect my computer's system time?

No. Changing the time zone in Outlook only affects how Outlook displays times in your calendar and email. Your computer's system time remains unchanged. If you need to change your computer's overall time zone, you must do that in your operating system settings, not in Outlook.

Can I set different time zones for different calendars?

No. Outlook uses one primary time zone for your entire account. All calendars in your account display times in that zone. If you need to track multiple time zones, use the second time zone display feature or create separate calendar views.

Why does my meeting show a different time than what was in the invitation?

This usually means the person who sent the invitation was in a different time zone when they created it. Outlook automatically converts meeting times to your local time zone for display. The meeting time itself has not changed — only how it appears in your calendar.
