Your PSMail subscription allows you to securely manage your calendar using iPhone, Android, Outlook, Mac, and any CalDAV supported client. Sending appointments, marking deadlines, adding a follow-up flag with date, or inviting people to a party can all be accomplished from any number of devices, and changes made in one place (like your phone) updates your calendar entries on all your devices that are connected to PSMail. You can also quickly access your calendar from a remote computer (such as a friend’s) or securly when you are traveling (even at an airport) through our webmail at https://mail.psmail.net/iCal/ !
You can also share calendars with other PSMail and external subscribers in a variety of ways (including read-only sharing or anonymous sharing). Shared calendars can be extremely helpful for synchronizing schedules, showing availability, planning events, calling meetings, etc. All users who share calendars with full access through this service must have a PSMail account. However, remote users can be given limited access to a PSMail user’s calendar in order to view availability (Free/Busy search or anonymous view of the calendar).
