  • Yeah, I had this problem recently. At my work we are using a calendar and I can’t either share it privately and I can’t find a way to solve it. I found a lot of different answers on Reddit but they were not working properly. So, I am looking for the right solution. Please help me!

  • The problem I encountered recently was the same as yours. I am unable to share my work calendar privately or find it in the calendar I use , so I need a solution. Reddit had many different answers, but none of them worked properly. So I'm searching for a solution that works. Can you help me?

  • Hi guys,

    Today, i'll update an Exchange Server 2019 from CU9 to CU11.

    Exchange Server 2016 is already in the latest CU22 version.

    I'm going to update 1 host Exchange Server 2019 from CU9 to CU11 to see if the accounts that are on that updated server have this feature available again.

    After testing and seeing the results I will post it here on this forum.

    See ya.

  • So guys, (Update)

    The problem still persists even using the latest version of CU22 for exchange 2016 and latest version of CU11 for exchange 2019, this feature does not work during coexistence.



    4 Exchange Servers 2016 CU22 Frontend; Only CAS Function | CAS Role

    6 Exchange Servers 2019 CU11 Backend; Only MBX Function | MBX Role



    Internet ==> HLB (Hardware Load Balancer) ==> CAS ==> MBX

    PS: I applied the Security Updates for both versions as well, but I tried it before without applying it and it didn't work either.

    No luck.

  • As your anonymous calendar sharing url is not working in Exchange. I would like to suggest that you should checkout this Microsoft technocommunity blog here:

  • I did this configuration too. No sucess.

    If i access directly through an Exchange Server 2019 CU9, the feature works perfectly.
