I have a user who has a fresh installation of Office 2016 (and Outlook 2016).
She wants to share the details of her calendar with a user on Office 2013 (and Outlook 2013).
Proper requests and sharing steps appear to have been completed corrected. However, the person running Outlook 2013 cannot view the details of the Outlook 2016 user's calendar. Only free/busy data is shown.
Both users are part of the same organization and same domain. Each user's mailbox is stored even stored on the same email server.
Any suggestions on how to fix?
