Show the time it takes.
Show how much time the meeting takes across everyone invited.
Could this be an email? A small pause before someone sends an invite, so they can decide whether the conversation really needs a meeting.
One last question
Could you get the same result with an email, message or shared document?
Try something lighter
The person booking it sees 30 minutes. Across six people, that is three hours gone, before you count the time it takes to stop and restart their work.
In an Atlassian workplace survey, 78% of respondents said meetings made it harder to finish their work. Eighty percent said they would be more productive with fewer meetings.
The issue is not meetings themselves. It is that booking one is often easier than choosing a better way to communicate.

One click should turn the invite into an email, chat or shared document. The reminder should help, not scold.
Some conversations really do need a meeting. Ask what it needs to accomplish, then get out of the way.
The idea: a small pause at the right time may lead to better choices. It will not fix a bad meeting culture on its own.
These are mockups, not screenshots of a working product. The numbers and responses are examples. Outlook offers the clearest way to build it into the product. Google would likely need a Chrome extension installed by the company.
Would people actually turn a meeting invite into an email, chat or shared document?
Would it reduce meeting time, or would the same work simply show up somewhere else?
Would the meetings that still happen have a clearer purpose, fewer people or less time on the calendar?
Would people find the reminder useful, easy to ignore or irritating?
