Can Interview Time Slots be removed based on the Interviewer's Outlook calendar?

Summary:

We use Candidate Managed Interview Schedules with the Microsoft integration. Interviewer's time slots are automatically removed if a candidate on a different requisition takes one. This prevents multiple candidates from occupying the same slot. However, the Microsoft calendar is not impacting time slot availability. Even if the interviewer accepts outside meeting invites, those slots are still available for candidates to select, which double-books the interviewer.

How do you all deal with this?

Example:

Hiring Manager Sally is available to interview candidates from 2pm to 4pm every day, in 30-minute increments.

Recruiter Jesse adds an onsite, Candidate Managed interview schedule to the requisition, and creates the time slots for the upcoming week.
