Free Busy search from External Tenant

We have a contractor that wants to do free busy searches on a few users calendars to schedule meetings.

Since they are not part of our tenant, can they search?

What do I need to do to allow this from that person's Domain?

If I go to Exchange Admin Center and then to Organization do I add it under the "Organization Sharing" section?

If I do is that secure?

    Hi David Kamp,

     

    Adding the external domain under "Organization Sharing" is a secure way, make sure you select "Calendar free/busy information with time only". Once this is done, any user in the external tenant will be able to view the calendar free/busy of all/specific users in your tenant (depending on what you selected in the Org. Sharing).

     

    An alternative is for those specific users in your tenant to https://support.microsoft.com/en-us/office/share-your-calendar-in-outlook-on-the-web-7ecef8ae-139c-40d9-bae2-a23977ee58d5?ui=en-US&rs=en-US&ad=US with the specific external user (provided external sharing has been enabled in your tenant).
