Minimum amount of hours before booking available for others

Hi everyone,

where can I set the option that others can only book times with me at least 36 hours in advance so I can avoid, e.g., that someone books the next hour, even if the slot is still free? I simply need more time to prepare etc.

I know this is possible in Google calendars, but I am using outlook. Don’t want to switch to GMail.

Thanks.
