I created a new mailbox user shared@. Then I shared the calendar to all the users in the company. When a user sends a meeting invitation, I only want that user to get a confirmation. Currently, everyone without delegation rights are unable to get the invite response. Also, everyone with the delegation rights are receiving ALL responses, even to the events they did not send. How do I share a calendar and when that user sends a meeting invitation only that user gets a response?
*I know I can do a public folder, but I saw that public calendar is only available in Outlook. Users need it to work on mobile devices.
