The problem had to do with how exchange handles calendar permissions depending on how you choose to open the calendar and how the sharing invitation is sent.
MICROSOFT ONLINE CALENDAR SHARING UPDATE
In our case, everything was setup correctly and the CU16 update for 2013 did nothing to change the behavior. Unfortunately there is a lot of incorrect and incomplete information about this process online. I wanted to update this in case anyone else comes across this issue. If I change the default permission on my calendar to allow details, then I can see details with an account on-prem but that's not an acceptable solution.Īs I said, it's the same behavior in both directions and free/busy lookups are working correctly in both directions. it just acts like it's not using the organization relationships. Test-OrganizationRelationship shows success in both environments. I ran the HCW to setup the hybrid environment. Time with Subject and Details" is allowed.

I also have the Organization Relationships defined so that "Free/Busy I have the default sharing policy in both locations set to allow "Free/Busy Time with Subject and Details" with both "All Domains" as well as "Anonymous". On-prem with O365, can only see Free/Busy with time. The issue I can't seem to figure out is that O365 users that have their calendar shared with on-prem and Everything is working fine where on-prem users can see cloud users and cloud and can on-prem.
