How can i apply this only for my calendar and not for all envent users?
Thanks in advance,
As an exchange user in Microsoft Outlook, you can set permission for others to view the Free/Busy information in your calendar. Therefore, other users can pick up free time for group schedules, such as meeting. Apart from the permission of viewing Free/Busy information, you need to mark your appointments as busy, free, or others. This article will guide you to show appointments in calendars as busy, free, tentative, or out of office in Microsoft Outlook.
The following steps will guide to you show your appointments as busy, free, tentative, or out of office.
Step 1: Create a new appointment:
Step 2: In the Appointment window, click the Show As: box in the Options group on the Appointment tab.
There are five options in the drop down list of Show As: box: Free, Tentative, Busy, Out of Office, and Working Elsewhere. You can select one of them based on your needs.
Step 3: Compose your appointment, and click the Save & Close button.
Then these appointments will be marked and shown as Free, Busy, Tentative, or Out of Office, both in your Outlook and in other exchange users’ Outlook who share your calendar information. See screen shot:
