A lot of people try to protect the content of their appointments by marking them as “Private”.
Unfortunately, the mail server does not actually conceal the content. Exchange merely flags the appointments as “Private” in its design. It is the clients’ job to respect the marking.
Recommendation
Do not publish any sensitive or confidential information in Exchange appointments. Instead, communicate such information separately.
