Sharing a calendar

The university's calendar system contains default settings which allow all users to see the availability information of other users. In practice, this means that others can see whether your calendar has a "free", "busy", "tentative" or "out of office" status for a given time. If you want to grant more permissions to others, follow these instructions.

  • Click the SHARE link at the top right corner of the calendar.

  • In the Share with: text field (1), type the name of the person you want to let view your calendar. The application automatically searches for people when you start typing the name.

  • In the drop-down menu (2), choose how much information you want to share.
    • Availability only means that the other person sees when you are busy, but they don't see any detailed information of the calendar item.
  • You can change the subject of the e-mail in the Subject field if you like.

  • When you are finished, click SEND. The selected persons receive an invitation by e-mail.

Viewing other calendars

The university's calendar system contains default settings which allow all users to see the availability information of other users. To use other people's calendars, see Basic information in these instructions. If someone shares more permissions to their calendar to you, do as is explained in Extended information.

Basic information

  • In the calendar view, right-click the OTHER CALENDARS text in the left.

Extended information

If someone grants you permissions to their calendar exceeding the basic permissions, do as follows:

  • More detailed information is shown in point (2).
  • Click ADD CALENDAR to accept the request (3).
  • You can share your own calendar with the person who sent you the invitation under (4).

  • The calendars of other people are shown on the left side of the calendar view under your own calendar.

  • You can specify different colours for the calendars. This makes it easier to manage various calendars.
  • Right-click the other user's calendar.
  • Choose > color > the colour of your choice.

  • Click any calendar to temporarily show or hide it. If there is no tick by the calendar, the items of the calendar in question are not shown in the calendar view. In the example, the user's own items (1) and those of person (2) are shown. The items of person (3) are hidden.
