Hello Daisy White,
Thanks for your post in this community.
Based on your post, have checked from our end and seems it isn’t feasible to undo such import action. However as it is imported in your own calendar, so to remove such iCalendar’s events from your personal calendar, you need to delete it by follow the below steps.
Here is the steps:
- For this, open Outlook > navigate to the calendar > select your personal calendar folder > now go to View tab > Select change view, then select list
- Hold down Ctrl key and select the imported items/events from the list view and then press delete.
We appreciate your kind understanding and co-operation on this post.
Thank you so much for your precious time. Have a nice day and be safe with good health.
Regards,
Ankita Vaidya
