You can delete a calendar in Outlook by right-clicking it and choosing delete, but the steps differ slightly depending on whether you use Outlook on the web, the desktop app, or Outlook on your phone
The fastest way to remove a calendar you no longer need is to find it in your calendar list, right-click it, and select the delete option. The calendar disappears from your sidebar immediately. However, what happens to the events inside depends on which version of Outlook you are using and whether the calendar is one you created or one someone shared with you.
If you share calendars with colleagues or family members, deleting your copy does not affect their copies — they keep seeing the calendar on their end. If someone else created the calendar and shared it with you, deleting it only removes it from your view. The original calendar stays in their account.
Key Takeaways
- Right-click any calendar in your sidebar and select delete to remove it from your view in seconds.
- Deleting a shared calendar only removes it from your account, not from the person who created it.
- Events in a deleted calendar are permanently removed from your Outlook account, so make sure you do not need them before deleting.
- The delete option works the same way in Outlook on the web and the Outlook desktop app, though the menu locations differ slightly.
How to delete a calendar in Outlook on the web
Open Outlook in your web browser and look at the left sidebar where your calendar list appears. Find the calendar you want to remove. Hover your mouse over the calendar name until a three-dot menu icon appears to the right of it.
Click the three-dot menu and select Delete calendar from the dropdown. A confirmation message will appear asking if you are sure. Click Delete again to confirm. The calendar vanishes from your list immediately, and all events stored in that calendar are permanently removed from your Outlook account.
How to delete a calendar in the Outlook desktop app for Windows or Mac
Launch Outlook on your computer and look at the left sidebar under the My Calendars section. Find the calendar you want to delete. Right-click directly on the calendar name.
A context menu will pop up. Select Delete Calendar from the list. Outlook will ask you to confirm the deletion. Click Yes to proceed. The calendar is removed from your sidebar and all its events are permanently deleted from your Outlook account.
If the calendar you want to delete appears under Other Calendars instead of My Calendars, the process is identical — right-click the name and select delete.
How to delete a calendar in Outlook on your phone
Open the Outlook app on your iPhone or Android phone and tap the Calendar icon at the bottom of the screen. Look for the calendar list, which may be labeled Calendars or My Calendars depending on your phone type.
On an iPhone, swipe left on the calendar name you want to delete. A red Delete button appears. Tap it to remove the calendar. On an Android phone, long-press the calendar name until a menu appears, then select Delete. Confirm the deletion when prompted.
What happens to events when you delete a calendar
Every event stored in that calendar is permanently removed from your Outlook account. You cannot undo this action, so before you delete, make sure you do not need any of the events inside. If you are unsure, consider moving important events to a different calendar first instead of deleting.
If the calendar was shared with other people, those people still have their own copies of the calendar and all its events. Deleting your copy does not affect theirs. However, if you created the calendar and shared it with others, deleting it removes it from your account only — the people you shared it with must delete their copies separately if they want to remove it.
How to remove a shared calendar without deleting it
If someone shared a calendar with you and you want to stop seeing it without permanently deleting it, you can hide it instead. In Outlook on the web, uncheck the box next to the calendar name in your sidebar. In the desktop app, right-click the calendar and select Hide instead of Delete. On your phone, toggle the calendar off.
The calendar stays in your account but disappears from your view. You can show it again later by checking the box or toggling it back on. This is safer than deleting if you think you might want to see the calendar again.
Frequently Asked Questions
Can I undo deleting a calendar?
No. Once you delete a calendar in Outlook, it and all its events are permanently gone. There is no undo or recovery option. If you deleted a calendar by mistake, you would need to recreate it manually or ask someone to reshare it with you if they have a copy.
What if I delete a calendar someone shared with me?
Deleting a shared calendar only removes it from your account. The person who created it still has it, and anyone else they shared it with still sees it. You are only removing your own copy from your view.
Will deleting a calendar delete events from other people's calendars?
No. If you created a calendar and shared it with colleagues or family, deleting it from your account does not affect their copies. They must delete it separately from their own accounts if they want to remove it.
How do I delete just one event instead of the whole calendar?
Right-click or long-press the individual event and select delete. This removes only that event, not the entire calendar. The calendar itself stays in your account with all other events intact.
Can I delete a calendar if I do not remember its password?
You do not need a password to delete a calendar in Outlook. If you can see the calendar in your sidebar, you can delete it using the steps above. If you cannot access your Outlook account at all, you would need to reset your account password first.
