One of the most convenient features of an online calendar is the ability to view not only your own events, but the events of friends, family, and coworkers who have shared their calendars with you. The following steps explain how your acquaintances can share their calendars with you, allowing you to view them alongside your own in PSCalendar.
Step 1: You need to first request that your friend logs into his/her PSMail account and choose the Calendar option along the left-hand side bar.
Step 2: Then, in the Pick Multiple box, they should choose the appropriate calendar and click Share.
Step 3: A new window will open and the user can enter your PSMail email address as a Read Only sharing partner for their calendar.
Step 4: Then they should click Add.
You can use many email clients (such as Outlook) and calendar clients (such as Sunbird, Mac Calendar, Android, iPhone) to view all the shared calendars. Shared calendars are exposed via a simple URI: https://mirror.psmail.net/shared.ics
