Managing a Calendar Other Than Your Own

To manage a calendar other than your own, the calendar owner must share the calendar to you with permissions to Make Changes to Events or Make Change AND Manage Sharing.

Schedule an Event on Behalf of a Person or a Location/Resource

The calendar must be shared to you with permission to Make Changes to Events or Make Change AND Manage Sharing.

When creating an event, use the Calendar drop-down and select the name of the calendar that you want to schedule from (see image below).

If you are scheduling on behalf of a person: Be aware that when the event is scheduled, the calendar owner will also receive an invitation so that they are aware that the event was created. However, that invitation does not require any action on the part of the calendar owner because the TOP "Yes" will already be selected.

Accept/Decline an Event on Behalf of a Person or a Location/Resource

The calendar must be shared to you with permission to Make Changes to Events or Make Change AND Manage Sharing.
You must have notifications turned on for the calendar you manage.

Invitations received on behalf of someone else can be accepted/declined by clicking on the more details link in the invitation.
