Note: Delegate access permission must be set using Outlook before the following actions can be performed.
1. Open your Outlook 2013 Client.
2. Click the Calendar button located in the bottom left corner of Outlook.
3. Once the ribbon has adjusted to reflect calendaring options, select Open Calendar, then Open Shared Calendar.
4. Select the person, from Global Address List, that has provided you delegate access to open their calendar. The calendar will be displayed under Shared Calendars.
Note: Creating a meeting on behalf of another will not include the delegate, within the invitation, as an attendee by default. Additionally, all created items will reflect the current calendar owner as the Meeting Organizer.
