Anonymous Calendar Sharing URL in Exchange is not working between Exchange 2016/2019 coexistence
Hi guys, (Scenery) I have 4 Exchange Servers 2016 CU22 Frontend; Only CAS Function | CAS Role I have 6 Exchange Servers 2019 CU9 Backend; Only MBX Function | MBX Role (Flow) Internet ==> HLB (Hardware Load Balancer) ==> CAS ==> MBX PS: Exchange Server 2016 CU22 is kept as CAS Role to maintain compatibility with older email clients. All users when accessing shared calendar settings get this error <HTTP ERROR 500> below using Exchange Server 2016 CU22 with proxy function. But. if i access directly through an Exchange Server 2019 CU9, the feature works perfectly. Follow the configuration: Any ideas guys? T
