Hi,
To see meetings in diary you should to calculate activities in the planning screen.
It works if you add attendees on your meeting.

I hope this will help you.

Thank you but
- I did not ask to see the meeting in the Planning (Menu Follow Up - Planning)
- I asked to see it in the Diary (Menu Follow Up - Diary)

To see meeting on diary you need to calculate planning before .

I may complete Krowry's answer.

In the Diary view, you can see two kinds of items :
- non plannable items (Tickets, Actions, ...) : they are displayed for responsible on due date.
- plannable items (Activities, Meetings, ...) : they are displayed on every date having some planned work for selected resource.

All works fine.
Thank you!
