How Do I Delete A Calendar In Outlook

Removing a calendar from Outlook requires navigating to your calendar list and selecting the delete option. If you’ve been wondering how do i delete a calendar in outlook, this guide walks you through every step for both desktop and web versions.

Outlook lets you manage multiple calendars, but sometimes you need to clean things up. Maybe you created a test calendar or no longer need a shared one. Whatever the reason, deleting a calendar is straightforward once you know where to look.

This article covers the exact steps for Outlook 365, Outlook 2021, Outlook on the web, and the mobile app. You’ll also learn what happens after deletion and how to avoid common mistakes.

Before you start, understand that not all calendars can be deleted. Your default calendar—usually called “Calendar”—cannot be removed. You can only delete additional calendars you created or imported.

Shared calendars from other people also have restrictions. If someone shared their calendar with you, you can remove it from your view, but you don’t actually delete their calendar. You’re just hiding it.

What Happens When You Delete A Calendar

When you delete a calendar in Outlook, all events and appointments stored in that calendar are permanently removed. There is no recycle bin or undo button for calendar deletion.

If the calendar was shared with others, they lose access too. Make sure you export important events before deleting if you might need them later.

Deleting A Calendar In Outlook Desktop App (Windows)

The desktop version of Outlook gives you the most control. Here is how to remove a calendar step by step.

Open Outlook and click the Calendar icon at the bottom left of the window.
Look at the left sidebar under My Calendars. You’ll see all your calendars listed there.
Right-click the calendar you want to delete. A context menu appears.
Select Delete Calendar from the menu.
A confirmation dialog box asks if you’re sure. Click Yes to confirm.

That’s it. The calendar disappears from your list, and all its events are gone. If you don’t see the delete option, the calendar might be your default one or a shared calendar you can’t delete.

Alternative Method Using Calendar Properties

Sometimes the right-click method doesn’t work. Try this alternative.

Go to Calendar view in Outlook.
Click File in the top left corner.
Select Account Settings then Account Settings again.
Go to the Internet Calendars tab.
Find the calendar you want to remove and click Remove.
Click Yes to confirm.

This method works best for calendars you subscribed to online, like holiday calendars or sports schedules.

Deleting A Calendar In Outlook On The Web

Outlook on the web (OWA) has a slightly different interface. Here’s how to delete a calendar using your browser.

Go to Outlook.com or your work Outlook web access page.
Sign in with your credentials.
Click the Calendar icon at the bottom of the left navigation pane.
On the left side, find the calendar you want to delete under Other calendars.
Click the three dots (more options) next to the calendar name.
Select Delete from the dropdown menu.
Confirm the deletion when prompted.

If the calendar is under My calendars, you can still delete it the same way. Just remember that your primary calendar cannot be removed.

Removing A Shared Calendar In Outlook Web

Shared calendars from colleagues appear under People’s calendars. To remove one from your view:

Hover over the shared calendar name.
Click the X that appears next to it.
The calendar is removed from your list but not deleted from the owner’s account.

This is useful when you no longer need to see someone else’s schedule. You can always add it back later if needed.

Deleting A Calendar In Outlook For Mac

Outlook for Mac works differently than the Windows version. Follow these steps to remove a calendar on macOS.

Open Outlook and click Calendar in the navigation bar.
Look at the left sidebar for the list of calendars.
Control-click (or right-click) the calendar you want to delete.
Choose Delete from the context menu.
Click Delete again to confirm.

On Mac, you might also see an option to Hide instead of delete. Hiding just removes it from view temporarily. Deleting removes it permanently.

What If The Delete Option Is Greyed Out

If you cannot click delete, the calendar is likely your default one. You cannot delete the main calendar in Outlook. You can only rename it or create a new one.

Another reason could be that the calendar is part of an Exchange account managed by your IT department. In that case, contact your administrator for help.

Deleting A Calendar In Outlook Mobile App

The Outlook mobile app for iOS and Android has limited calendar management features. You can remove calendars from view, but actual deletion is harder.

To remove a calendar from the mobile app:

Open the Outlook app on your phone.
Tap the Calendar icon at the bottom.
Tap the hamburger menu (three lines) in the top left.
You’ll see a list of calendars. Tap the gear icon next to the calendar you want to remove.
Select Remove from list or Delete if available.

Note that on mobile, you might only be able to hide calendars, not delete them permanently. For full deletion, use the desktop or web version.

How To Delete A Calendar Group In Outlook

Calendar groups let you view multiple calendars at once. If you created a group and want to remove it, here’s how.

In Calendar view, look at the left sidebar.
Right-click the calendar group name.
Select Delete Group from the menu.
The group is removed, but the individual calendars inside it remain.

Deleting a group does not delete the calendars themselves. It just removes the grouping so you see them separately again.

How To Delete A Birthdays Calendar In Outlook

Outlook automatically creates a Birthdays calendar from your contacts. Some users find it annoying. To remove it:

Go to Calendar view.
Under My Calendars, find Birthdays.
Right-click it and select Delete.
Confirm the deletion.

If the Birthdays calendar reappears after some time, it’s because Outlook syncs it from your contacts again. To prevent this, remove birthday data from your contacts or hide the calendar instead.

How To Delete A Holiday Calendar In Outlook

Holiday calendars are easy to add but also easy to remove. Follow these steps.

Open Calendar view.
Find the holiday calendar under Other Calendars or My Calendars.
Right-click it and choose Delete Calendar.
Click Yes to confirm.

Holiday calendars are usually internet subscriptions. Deleting them removes all holiday entries. You can always add them back later from the Outlook settings.

What To Do Before Deleting A Calendar

Before you delete any calendar, take these precautions.

Export events if you might need them. Use the export feature in Outlook to save calendar data as a CSV or ICS file.
Check for recurring events that might be important. Recurring appointments are deleted along with the calendar.
Notify others if the calendar was shared. Let them know you’re removing it so they aren’t surprised.
Double-check the calendar name to make sure you’re deleting the right one.

Once deleted, there is no way to recover the calendar or its events. Microsoft does not provide a trash bin for calendars.

How To Recover A Deleted Calendar In Outlook

If you accidentally delete a calendar, you might be able to recover it if you act quickly. Here are your options.

Check the Deleted Items folder in Outlook. Some calendar deletions go there, but not all.
Use the Recoverable Items folder in Exchange accounts. IT administrators can sometimes restore deleted calendars.
Restore from a backup if you exported the calendar before deleting.
Re-add a shared calendar if it was shared by someone else. Ask the owner to reshare it.

For most users, recovery is not possible. That’s why exporting is so important.

Common Mistakes When Deleting Calendars

Avoid these errors to keep your Outlook clean.

Deleting the wrong calendar because you have multiple similar names. Always read the name carefully.
Thinking hiding equals deleting. Hiding a calendar just removes it from view. It still exists and syncs.
Deleting a shared calendar thinking it removes it for everyone. It only removes it from your view.
Not exporting first and losing important appointments.

Take your time and verify before clicking delete.

How To Hide A Calendar Instead Of Deleting

If you’re not sure about permanent deletion, hide the calendar first. Hiding is reversible.

In the desktop app, uncheck the box next to the calendar name. In Outlook on the web, click the eye icon next to the calendar. On mobile, toggle the switch off.

Hidden calendars still sync and receive updates. You just don’t see them. This is useful for seasonal calendars or shared calendars you only need occasionally.

Why Can’t I Delete My Default Calendar

Your default calendar is tied to your email account. Outlook requires at least one calendar to function. Deleting it would break the calendar feature.

If you want a fresh start, create a new calendar and set it as your default. Then hide the old one. But you can never truly delete the primary calendar.

How To Delete Multiple Calendars At Once

Outlook does not have a bulk delete feature for calendars. You must delete them one by one. If you have many calendars to remove, consider these tips.

Delete them in the web version where the interface is faster.
Use the Account Settings method to remove internet calendars in bulk.
Contact IT support if you have dozens of calendars from shared sources.

There is no workaround for deleting multiple calendars simultaneously in standard Outlook.

How To Delete A Calendar In Outlook 365

Outlook 365 works similarly to the desktop version. The steps are identical to those listed earlier. The only difference is that your calendars sync across devices, so deleting on one device removes it everywhere.

Make sure you’re signed into the same account on all devices before deleting.

How To Delete A Calendar In Outlook 2019 Or 2016

Older versions of Outlook have the same interface. Follow the desktop app steps above. The right-click method works in Outlook 2016, 2019, and 2021.

If you’re using Outlook 2010 or 2013, the process is similar but the interface looks older. Look for the calendar list on the left and right-click there.
