Hello on 2 march 2020 I received a refund for a support request from Microsoft. The Exchange error : [Ticket #:18773134] was accepted as a bug. But meanwhile after one year and with the last CU20 the bug is still present, has not been fixed. As far as I know for Exchange 2016, the last CU will be published in June 2021. After that, there will only be security updates for Exchange 2016. Will Microsoft still fix this bug in Exchange 2016 or will it remain unaddressed? What happens now? Does anyone have any ideas? What can I do? I need a solution and would be very grateful for any advice.
