How do I change calendar event availability status to 'Out of Office'?

To change your availability status to "Out of Office "(displayed in purple), the System Administrator must first add the field "Show Time As" to the page layout.  If you do not have the ability to edit page layouts, then you'll need to contact your System Administrator.  If you are a System Administrator, then the steps below can be used:

1. Click on: Setup | App Setup | Customize | Activities | Event Page layouts.

2. Edit the desired page layout.

3. Click and drag the "Show Time As" field into the page layout

You can now change your availability status to "Out of Office" (red), "Busy" (purple), or "Available" (no color).
