If someone has granted you permission to view their calendar or mailbox, complete the following steps to view their calendar in Outlook Web App (OWA):

1. Open a Web browser and log in to OWA.

2. Click on your name in the top right corner.

3. Click Open another mailbox...

4. Enter the email address of the mailbox you want to open

If you do not have permission to view someone's calendar or you do not want to open their calendar, you can view just their availability in OWA:

2. Click the calendar icon at the bottom of the screen

3. Right click your calendar name in the left-hand navigation pane

4. Select Open Calendar
5. Type the name or email address of the person whose calendar you want to open
6. Click Open
