Question details

The user needs to remove an individual calendar entry synchronized from ClickUp into New Outlook, but only sees a 'Duplicate' option instead of 'Delete'.

How to Delete a ClickUp Calendar Entry in New Outlook

Product: New Outlook
Device & OS: not provided
Scenario: Managing and cleaning up synchronized third-party calendar events in the Outlook calendar interface.
Observed behavior: The delete option is missing for synced ClickUp entries in New Outlook; the system only displays the option to duplicate the event.

Before you start

Verify whether the calendar entry was created directly in Outlook or synchronized from a third-party application like ClickUp. Ensure you know the source of the calendar, as synced internet calendars are often read-only.

Solution 1Recommended

Delete the Event Directly in ClickUp

Since synchronized calendars are typically read-only in Outlook, deleting the source task in ClickUp is the most reliable way to remove the entry.

When you sync a ClickUp calendar to Outlook, Outlook treats it as a one-way feed. This means you cannot edit or delete the individual items from within Outlook itself. You must manage the data from the source.

Open ClickUp

Delete or Unschedule the Task

Either delete the task in ClickUp entirely, or remove its due date and time if you want to keep the task but remove it from the calendar.

Wait for Synchronization

Allow some time for the changes to sync. Alternatively, you can click 'Send/Receive All Folders' in Outlook to force a manual refresh of the calendar feed.

Sync Delay: It may take anywhere from a few minutes to a few hours for the calendar feed to refresh in Outlook after you make a change in ClickUp.

Solution 2

Attempt Deletion via Outlook on the Web

Sometimes the web version of Outlook offers different sync management options or permissions compared to the New Outlook desktop application.

Solution 3

Remove the Entire Synced ClickUp Calendar

If you no longer need ClickUp events in Outlook, you can remove the entire synchronized calendar to clear all related entries at once.

Frequently Asked Questions

Why does Outlook only show the duplicate option for my calendar event?

This happens when an event belongs to a read-only calendar synced from a third-party service like ClickUp. Because you do not have write permissions to alter the source data from within Outlook, the system disables the delete and edit options, leaving only the ability to duplicate the event into a local calendar.

How long does it take for ClickUp to sync calendar changes to Outlook?

Syncing times depend on Outlook's server refresh rates for subscribed internet calendars. It typically takes anywhere from a few minutes to several hours for a deleted ClickUp task to disappear from your Outlook calendar.

Can I edit ClickUp events directly in New Outlook?

No, calendar feeds generated by ClickUp are read-only in Outlook. To change an event's date, time, or specific details, you must make the modifications directly within the ClickUp platform.
