Environment

Resolution
Please go this Microsoft Link and follow the instructions, Microsoft Article on Delegate Access
To provide Calendar access only, follow the instructions here, Microsoft Link for Calendar Access Permissions
Cause
By default, Outlook Calendar will send confirmation Calendar Appointment messages to your primary mailbox with your own email address. But if you have granted access to another person's mailbox and made them a delegate, they will be able to manage your Calendar and receive invitations.
