If you created a new calendar in Outlook on the Web you may notice the option to delete it might be missing. I see this question come up quite a lot so figured it was time to address it with a blog post.
The issue occurs when a user creates a calendar in Outlook on the Web. Often the calendar is created in error because the user was trying to add a shared calendar instead. When the user right-clicks the calendar they will see no option to delete.
We have an example of this in the screenshot below. The user has created a calendar titled, “My New Calendar”. However, when they right-click there is no option to delete.
