The fastest way to add a shared calendar in Outlook
To add a shared calendar in Outlook, you need the calendar owner's email address and their permission to view it. The owner must first share the calendar with you (a step they control on their end), then you add it to your view by opening the "Add Calendar" menu and selecting "Subscribe to a Calendar" or "From Directory," depending on whether the calendar is already shared with you or lives in your organization's directory.
The exact steps depend on whether you use Outlook on the web, Outlook desktop, or Outlook mobile. All three work, but the menu locations are different. Desktop is usually fastest if you're already working there; web-based Outlook works from any computer; mobile is useful for checking shared calendars on the go but clunky for adding them the first time.
Key Takeaways
- The calendar owner must share the calendar with you first — you cannot add a calendar you do not have permission to see.
- In Outlook desktop, right-click the calendar list on the left side and choose "Add Calendar" to find shared calendars from your organization or by email address.
- In Outlook on the web, click the plus sign next to "Calendars" in the left panel and select "Subscribe to a Calendar" to paste in someone's email address.
- Once added, a shared calendar appears in your calendar list and you can toggle it on and off without removing it.
- You can only see events on a shared calendar if the owner gave you permission to view them — permission levels range from "view only" to "edit" to "delegate."
Adding a shared calendar in Outlook desktop
Open Outlook and look at the left sidebar where your own calendars are listed. Right-click in the empty space below your calendar name, or right-click directly on "Calendars" if that option appears. A menu will pop up with options including "Add Calendar." Click it.
A dialog box opens with two main choices: "From Directory" (for calendars within your organization) or "From Email" (for anyone with an email address). If you know the person works in your organization, try "From Directory" first and type their name — Outlook will search your company directory. If that does not find them, or if they work outside your organization, choose "From Email" and paste their full email address.
Click "Subscribe" or "Add." Outlook will attempt to connect to that calendar. If the owner has shared it with you, it will appear in your calendar list within seconds. If it does not appear, the owner has not yet shared it with you, or they shared it with the wrong email address. Ask them to check their sharing settings.
Adding a shared calendar in Outlook on the web
Log into Outlook at outlook.office.com or outlook.com. On the left side, find the "Calendars" section. Next to it is a plus sign (+). Click it.
A small menu appears with options including "Subscribe to a Calendar." Click that option. A text field opens asking for an email address. Type or paste the email address of the person whose calendar you want to add. Click "Subscribe."
If the owner has shared the calendar with you, it will appear in your calendar list when ready. If nothing happens, or if you see an error message, the owner has not shared it yet or shared it with a different email address than the one you entered.
Adding a shared calendar on Outlook mobile
On iPhone or Android, open the Outlook app and tap the calendar icon at the bottom. Look for a plus sign or a menu icon (three dots or lines) near the top. The exact location varies by phone and app version, but there is usually an option to "Add Calendar" or "Subscribe to Calendar."
Tap it and enter the email address of the calendar owner. The app will search for the calendar and add it if you have permission. Mobile is useful for viewing shared calendars once they are set up, but adding them for the first time is easier on a computer where you can see more of the interface at once.
What to do if a shared calendar will not appear
The most common reason a shared calendar does not show up is that the owner has not actually shared it with you yet. Ask them to open their calendar settings, find the sharing option, and confirm your email address is listed. They should also check what permission level they gave you — if they set it to "view only," you will see the calendar but not be able to edit events.
A second common issue is using the wrong email address. If you have multiple email accounts, make sure you are adding the calendar to the account that the owner shared it with. For example, if the owner shared it with your work email but you are trying to add it to your personal Outlook account, it will not work.
If you are using Outlook desktop and the calendar still will not appear after the owner has shared it, try closing Outlook completely and reopening it. Sometimes the app needs to refresh to pick up new shared calendars. If that does not work, try adding it again using the "From Email" method rather than "From Directory," or vice versa.
Managing shared calendars once they are added
Once a shared calendar is in your list, you can toggle it on and off by clicking the checkbox next to its name. Unchecking it hides the events but does not remove the calendar — you can turn it back on anytime without re-adding it. This is useful if you have many shared calendars and want to focus on just a few at a time.
To remove a shared calendar entirely, right-click its name in the calendar list (on desktop) or swipe left on it (on mobile) and select "Remove" or "Delete." This does not affect the calendar owner's calendar — it only removes it from your view. You can always add it again later if you need it.
If the owner changes the permission level on a shared calendar — for example, upgrading you from "view only" to "edit" — the change takes effect when ready. You do not need to re-add the calendar. If they remove your access entirely, the calendar will stop showing events, though it may still appear in your list until you remove it manually.
The difference between shared calendars and delegated calendars
A shared calendar is one where the owner lets you see their events but you manage your own calendar separately. A delegated calendar is one where you have full control over someone else's calendar — you can add, edit, and delete their events as if it were your own. Delegation is more powerful and is usually reserved for assistants or team leads managing a manager's schedule.
If someone wants to delegate their calendar to you, they do not add it through the "Add Calendar" menu. Instead, they go to their calendar settings, find the "Delegate" or "Permissions" option, and add your email address with full access. Once they do that, their calendar appears in your list with a special label indicating you have delegate access. You manage it the same way as a shared calendar once it is added, but you have more power to make changes.
Frequently Asked Questions
Can I add a calendar from someone outside my organization?
Yes. Use the "From Email" or "Subscribe to a Calendar" option and enter their email address. They must share their calendar with you first, and they must use an email address you can reach them at. If they use a different email for their Outlook account than the one you have for them, the sharing will not work.
What if I do not see the person's calendar in the directory?
They may not be in your organization's directory, or their name may be spelled differently than you expect. Try using "From Email" instead and enter their full email address. If that does not work, ask them directly for their email address and confirm it is the same one they use for Outlook.
Can I edit events on a shared calendar?
Only if the owner gave you edit permission. Ask the calendar owner to check their sharing settings and confirm what permission level they assigned to you. If they set it to "view only," you can see events but not change them. If they set it to "edit," you can add and modify events.
Will the calendar owner see when I view their calendar?
No. Sharing a calendar does not create a log of who looked at it or when. The owner only knows you have access — they cannot see your viewing activity. This is different from email, where read receipts can be turned on.
What happens if the calendar owner deletes their calendar?
The calendar will disappear from your list, and you will no longer see any events. If they recreate it and share it with you again, you will need to add it to your view using the same process as the first time.
