In order to Edit a meeting you have to be one of the following: administrator (can edit any meeting), supervisor (can edit any meeting), room owner (can edit meetings in their room), booker (can edit meetings which they originated).
After the meeting title is clicked in any of the calendar views a pop-up will appear, giving the user three different options.
The Details button displays all the details associated with the meeting in question. They cannot be modified directly. The Edit option is available at this level as well.
