PMIs are useful for both scheduled and instant meetings. However, when starting an instant meeting, the title of the IM is set to whatever the previously scheduled meeting title was that used the PMI. This is counter-intuitive for the user and creates security issues because today's instant meeting attendees maybe shouldn't be privvy to the topic of yesterday's IM. Ideally, IMs would always be started with a blank or generic title. If the issue is unclear, please refer to case 12917613 for explicit examples.
