Share calendar between Zimbra users

This post describes how to create shared calendars between two users in Zimbra 5.0

In this example, the administrator designates a mount point to userA@example.com for the calendar to  userB@example.com account for which he will have read/write permissions.

As user zimbra do the following

zmmailbox
mbox> adminAuthenticate -u https://server.example.com:7071 admin@example.com password
mbox> selectMailbox userB@example.com
mailbox: userB@example.com, size: 1.44 GB, messages: 20868, unread: 2564

mbox userB@example.com>createMountpoint --view appointment /userB-calendar userB@example.com /Calendar

userA@example.com should now see the calendar to userB@example.com as userB-calendar in the Calendar view.
