Support hybrid and dedicated O365 tenants
Michael Med commented
Any update on hybrid scenario? As Exchange supports modern authentication now I think there should be a chance to use findtime with hybrid scenario ...
Wouldn't Graph be able to provide a solution to this? There's a preview that supports on-premise exchange. See https://developer.microsoft.com/en-us/graph/docs/concepts/hybrid_rest_support and https://blogs.technet.microsoft.com/exchange/2016/09/26/on-premises-architectural-requirements-for-the-rest-api/

Vivek, the latest message on this was posted two years ago now, have the API's been updated sufficiently to support Hybrid deployments?

Since this is such a common ask, I thought I will provide some background on why it is not currently supported. FindTime uses Azure Active Directory issued tokens to access the Exchange mailbox in order to provide free/busy information and schedule on behalf of the organizer when required. Unfortunately, hybrid configurations do not support AAD tokens natively. This means we (the FindTime app code) cannot talk to the organizers mailbox without storing username and password. Due to security concerns, you can see why this is a path we do not wish to take.
I am hopeful, that it will become available as Exchange team rolls out features to support AAD token access for Hybrid and Dedicated tenants.
Till then, you can upvote to subscribe so that we can let you know when status changes.

This is critical for global organizations (like Microsoft) who have multiple instances of O365 tenancy in different regions. A combination of shared O365, dedicated O365, and on-premise instances of Exchange, all in mutually trusted configuration, make up the global communication and collaboration fabric of the company.
