Delete a calendar in Outlook by right-clicking it and selecting delete
To remove a calendar from Outlook, find it in the calendar list on the left side of your screen, right-click the calendar name, and choose Delete Calendar from the menu. Outlook will ask you to confirm. Once you confirm, the calendar and all events in it are permanently removed — you cannot undo this action.
The exact steps differ slightly depending on whether you use Outlook on the web, Outlook desktop, or Outlook on your phone. The principle is the same: locate the calendar, delete it, and confirm. But the location of the delete option changes between versions.
Before you delete, understand what happens to the events inside. If the calendar contains work you need to keep, move those events to another calendar first. If the calendar is shared with other people, they will lose access to it when you delete it.
Key Takeaways
- Right-click a calendar name in the left sidebar and select Delete Calendar to remove it permanently from Outlook.
- Deleting a calendar removes all events in it at once, so move important events to another calendar before you delete.
- If other people have access to the calendar, they will no longer see it after you delete it.
- The delete option appears in different places depending on whether you use Outlook desktop, Outlook on the web, or Outlook mobile.
- You cannot recover a deleted calendar, so double-check that you want to remove it before you confirm.
Delete a calendar in Outlook desktop
Open Outlook on your computer and look at the left sidebar where your calendars are listed. Find the calendar you want to delete. Right-click directly on the calendar name — not on an event inside it, but on the calendar name itself.
A menu will appear. Click Delete Calendar. Outlook will show a confirmation dialog asking "Are you sure you want to delete this calendar?" Click Yes to confirm. The calendar and every event in it will be removed when ready.
If you do not see the calendar list on the left, click the Calendar icon at the bottom of the sidebar to switch to calendar view. The calendar list should then appear.
Delete a calendar in Outlook on the web
Log into Outlook.com or your organization's Outlook web portal. Click Calendar in the left navigation. On the left side, you will see a list of your calendars under "My calendars" or "Other calendars."
Hover your mouse over the calendar name you want to delete. Three dots (a menu icon) will appear to the right of the calendar name. Click those three dots. Select Delete from the dropdown menu. Confirm that you want to delete the calendar when prompted.
If the calendar is shared with you by someone else, you will see a Remove option instead of Delete. Clicking Remove takes the calendar off your list but does not delete it for the person who owns it.
Delete a calendar in Outlook mobile
Open the Outlook app on your phone or tablet. Tap the Calendar tab at the bottom. Look for the calendar list — on iPhone, swipe left on the calendar name; on Android, long-press the calendar name.
A menu will appear with options including Delete. Tap Delete and confirm when the app asks you to verify. The calendar will be removed from your phone and from all your Outlook accounts connected to that phone.
Deleting a calendar on your phone removes it from your Outlook account everywhere — not just on that device. If you use Outlook on multiple devices, the calendar will disappear from all of them.
Move events before you delete a calendar
If the calendar contains events you need to keep, move them to another calendar before you delete. In Outlook desktop, right-click an event in the calendar you are about to delete. Select Move and choose the calendar where you want it to go. Repeat this for each event you want to save.
In Outlook on the web, click an event to open it. Click Edit. In the event details, find the calendar dropdown and select a different calendar. Click Save. Do this for each event you want to move.
Moving events one at a time takes time if you have many events. If you have dozens of events to move, consider keeping the calendar and just hiding it instead. Right-click the calendar name and select Hide — the calendar stays in your account but does not show on your screen.
What happens when you delete a shared calendar
If you created a calendar and shared it with other people, deleting it removes it from their view as well. They will no longer see the calendar in their calendar list, and they will lose access to all events in it. They cannot undo this on their end — only you can restore it, and only if you have a backup.
Before you delete a shared calendar, tell the people who use it. Ask them to move any events they need to keep to another calendar. If the calendar is used by a team or group, consider hiding it instead of deleting it, so people can still reference past events if needed.
If someone else shared a calendar with you and you want to stop seeing it, you do not need to delete it. Right-click the calendar name and select Remove (on the web) or Hide (in desktop). This removes it from your view without affecting the calendar owner or other people who have access to it.
Recover a deleted calendar
Outlook does not have a built-in undo for deleted calendars. Once you confirm the deletion, the calendar is gone. However, if your Outlook account is connected to Microsoft 365 or an Exchange server, your IT administrator may be able to recover it from a backup — but this depends on your organization's backup policies and how long ago you deleted it.
If you deleted a calendar by accident, contact your IT department or Microsoft support as soon as possible. The sooner you report it, the better the chance of recovery. For personal Outlook.com accounts, recovery is unlikely unless you have a recent backup of your computer or phone.
This is why moving events before you delete is important. If you keep the events, you can recreate the calendar structure later if you need to. If you delete both the calendar and the events, you have nothing to restore.
Frequently Asked Questions
Can I delete a calendar without deleting the events in it?
No, deleting a calendar removes all events in it. If you want to keep the events, move them to another calendar first. You can move events one at a time by right-clicking them and selecting Move, or by editing each event and changing its calendar in the dropdown.
What is the difference between delete and remove?
Delete removes a calendar you own and all events in it. Remove takes a calendar off your list when someone else owns it, but the calendar still exists for them and other people they shared it with. Use Remove for calendars other people shared with you, and Delete only for calendars you created.
If I hide a calendar instead of deleting it, can I get it back?
Yes. Right-click the hidden calendar name (it will appear grayed out or with a different icon) and select Show or Unhide. The calendar and all its events will reappear. Hiding is safer than deleting if you might need the calendar later.
Will deleting a calendar on my phone delete it from my computer too?
Yes. Deleting a calendar on your phone removes it from your entire Outlook account, including all computers and devices where you use Outlook. The deletion syncs across all your devices within a few minutes.
Can I delete a calendar if other people are using it?
Yes, you can delete it, but they will lose access when ready. Before you delete a shared calendar, ask the people who use it to move their events to another calendar or let them know the calendar is going away. Once deleted, they cannot recover it unless your IT administrator has a backup.
