The inbuilt scanning feature in Outlook automatically adds events to Calendar, based on the content of your emails. You will find below the steps to Prevent Outlook From Adding Calendar Events.
Prevent Outlook From Adding Calendar Events
If you are noticing a bunch of events in your Calendar that you did not add, these events are being automatically added by Outlook.
This feature in Outlook is designed to scan your emails and add events to the Calendar based on the content of your emails.
So if you receive an invitation by email, receive notice of package delivery, get confirmation of flight ticket booking or a hotel reservation, Outlook automatically adds these events to your Calendar.
While this feature can be useful, it can also end up cluttering your Calendar with a bunch of unwanted events.
If you prefer managing your calendar manually and do not like the idea of Calendar events being auto-generated, you can disable this feature by going to Outlook Email Settings.
