Free/Busy Hybrid Exchange 2019
Hello everyone, I have a hybrid environment with Exchange Server 2019, with a dedicated Exchange application, we renewed the Exchange Auth certificate and then re-ran the HCW, however, free/busy is not working for 365 Pro local users. Has anyone had this problem? Could you help me?
