Detailed help

Microsoft updates Office 365 services sporadically, thus functional and layout changes can occur. Therefore there can be discrepancies between these instructions and your updated version. Please use the feedback link at the bottom of this page in case you notice any significant discrepancies.

Basic calendar use

  • Log in at https://office365.helsinki.fi/
  • Open the calendar by clicking on the calendar icon in the bottom left-hand corner. (You can also open the calendar directly at https://outlook.office.com/calendar/)
  • In this example, the calendar is opened in the monthly view. You can switch to daily or weekly view at (1). Today’s date is 19 September (2). The next day is selected as active (3). There is one calendar entry for the day. Its information is shown in more detail on the right side of the window. Use the top bar links to navigate in the calendar (4).


Basic calendar settings

You can edit the calendar according to your preference by, for example, changing the presentation format of the date, the start and end time of your workday, event reminders and many other features.

Sharing a calendar

The university’s calendar system contains default settings which allow all users to see the availability information of other users.  If you want to grant more permissions to others, follow these instructions.

  • Click the Share link in the top right corner of the calendar. By default, members of the University of Helsinki have the permission Can view when I'm busy. You can change the default value in the drop-down menu People in my organisation (2).
  • You can also share permissions individually. In the text field (1), enter the name of the person you want to allow to view your calendar. The application automatically searches for people when you start typing the name. Click the name of the correct person (2).
  • Once you find the correct person (1), choose the information you want to share in the drop-down menu (2).
  • Click Share (3).
  • The selected persons receive an invitation by e-mail and will be displayed on the list (1). You can remove the permissions by clicking on the recycle bin icon (2).
  • The invited person receives an e-mail as pictured below. Item (1) indicates the shared level of permissions. Accept the invitation by clicking Accept (2).
  • You can open the calendar by clicking View calendar.


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, follow these steps.

  • In the calendar view, click Import calendar on the left-hand side (1).
  • Select From directory (2).
  • In the text field (1), enter the name of the person you are looking for. As you type, OWA proposes names which match. To select one of the proposed persons, click their name (2).
  • Click Add.
  • The calendar has been added to your list of calendars. In this example, Raimo’s calendar is marked with green to make it easier to see which entries are his and which are yours.
  • You can assign a colour for different calendars by clicking on the three dots next to the name. Open the Colour menu and select the colour.



Finding common time for a meeting and sending invitations

  • These instructions cover a quick and simple way of setting up a meeting. If you wish to book a meeting room and invite several attendees, see the instructions here.
  • In the calendar, click the date for which you want to set up a meeting.
  • Fill in the required information.
  • You can add attendees in section (2) Invite attendees.
  • You should enter information describing the meeting in the bottom text field unless the subject of the meeting is otherwise obvious to the attendees.
  • You can edit the time of the meeting in section (2). The right-hand column (3) is updated automatically and shows whether the attendees are available. In this example, one of the attendees was unavailable from 10:30 a.m. to 11 a.m. The meeting was rescheduled for 1–2 p.m. The green colour indicates that all the attendees are available during said time slot.
  • If there are several attendees or you wish to book a meeting room, we recommend using the Scheduling Assistant (4).
  • Send the invitation by clicking Send (5).


Replies to the invitation


Booking a meeting room

The bookings of some meeting rooms have been transferred to Outlook. Not all meeting rooms can be booked via Outlook. You can book a meeting room when you send the meeting invitation:


Replying to a calendar invitation

When someone sends you an invitation to attend a meeting, you receive an e-mail.

  • You can accept the invitation by clicking Yes, accept it tentatively by clicking Maybe or reject it by clicking No.
  • Once you accept an invitation, it creates an automatic entry in your calendar and the e-mail disappears.


Tracking the replies of attendees

  • As the organiser of the event, you can check the status of invitations by clicking on the calendar item. In this example, attendee Pitkänen, K Juhani (1) has accepted the invitation but the planned meeting room (2) has declined. If you are booking a room, remember that it always sends a response!
