How to Delete a Calendar in Outlook (And What to Know Before You Do)

Outlook gives you a lot of flexibility when it comes to managing multiple calendars — work schedules, personal appointments, shared team calendars, and more. But that flexibility also means the process of deleting a calendar isn't always the same. Where the calendar lives, how it was created, and which version of Outlook you're using all affect what steps you'll take — and whether deletion is even permanent.

What Kind of Calendar Are You Dealing With?

Before diving into steps, it helps to understand that Outlook treats different calendar types very differently. There are three main categories:

• Local calendars — created directly in the Outlook app, stored on your device or within your Outlook data file (.pst)
• Account-linked calendars — tied to an email account (like Microsoft 365, Exchange, Gmail, or iCloud) and synced through that account
• Shared or subscribed calendars — calendars shared by another person or imported via a URL (like internet calendar subscriptions)

Each type has its own deletion path. Trying to delete a shared calendar the same way you'd delete a local one often leads to confusion.

How to Delete a Calendar in Outlook on Windows (Desktop App)

For most users on the Outlook desktop app for Windows, here's the standard process:

1. Open Outlook and navigate to the Calendar view (click the calendar icon in the bottom-left navigation bar)
2. In the left panel, you'll see your list of calendars under headings like "My Calendars," "Other Calendars," or your account name
3. Right-click on the calendar you want to delete
4. Select "Delete Calendar" from the context menu

If that option is grayed out or missing, the calendar is likely tied to your primary email account — and Outlook won't let you delete a core account calendar (like your main Exchange or Microsoft 365 calendar) directly. In that case, you'd need to remove the entire account, or contact your IT administrator if it's a managed work account.

🗂️ Note: Deleted local calendars typically move to the Deleted Items folder first. You can recover them from there if needed, or permanently delete them by emptying that folder.

Deleting a Calendar in Outlook on Mac

The process on Outlook for Mac follows similar logic but with slightly different navigation:

1. Switch to Calendar view
2. In the left sidebar, locate the calendar you want to remove
3. Right-click (or Control-click) on the calendar name
4. Choose "Delete" or "Remove from Outlook" — the wording depends on the calendar type

Subscribed internet calendars will typically show "Remove from Outlook" rather than "Delete," which reflects that the calendar source lives externally — you're just disconnecting it, not destroying the source.

Deleting a Calendar in Outlook on the Web (OWA / Microsoft 365)

If you use Outlook on the web (outlook.com or your organization's Microsoft 365 portal):

1. Go to the Calendar section
2. In the left panel, hover over the calendar name
3. Click the three-dot menu (…) that appears
4. Select "Delete calendar"

Keep in mind that the web version syncs with your account, so deleting a calendar here also removes it from your desktop app and mobile app — wherever that account is signed in.

Removing a Shared Calendar vs. Deleting Your Own

There's an important distinction worth understanding here. If a colleague or another account shared their calendar with you, you typically remove it from your view rather than delete it outright. You don't own it, so you can't delete it — only the calendar owner can do that.

To stop seeing a shared calendar:

• Right-click it in the calendar list
• Choose "Remove" or "Remove from my calendars"

This removes it from your Outlook view without affecting the original calendar or notifying the owner.

Outlook Mobile (iOS and Android)

On the Outlook mobile app, calendar management is more limited by design. You can show or hide calendars, but deep deletion options are often restricted to the desktop or web versions. For most users, changes made in Outlook on the web will reflect on mobile automatically.

Variables That Change the Process

The steps above cover the most common scenarios, but several factors shape what you'll actually see:

What Happens to Events When You Delete a Calendar?

This is where many users get surprised. When you delete a calendar in Outlook, all the events inside that calendar are deleted along with it. There's no automatic export or backup unless you create one manually.

If you want to preserve any appointments before deleting:

• Export the calendar first via File → Open & Export → Import/Export → Export to a File (on desktop)
• Move important events to another calendar by opening each event and changing the calendar field

🔍 Once a calendar is permanently deleted (emptied from Deleted Items), recovery options are limited — especially for local calendars not backed up to a server.

Why the "Delete" Option Is Sometimes Missing

If you right-click a calendar and don't see a delete option, it usually means one of these things:

• It's your primary account calendar (Outlook protects these by default)
• It's a system calendar like Birthdays or Holidays, which Outlook manages automatically
• Your account has restricted permissions (common in corporate environments)
• You're looking at a read-only shared calendar where you're not the owner

Understanding which type of calendar you're working with — and who owns it — is the key variable that determines how far you can go with deletion in any version of Outlook.
