Hi,I'd be happy to help you out with your question. Sorry for the inconvenience caused.Enabling TLS 1.3 on your Windows Server Exchange 2022 involves a few steps. First, you need to make sure that your server is updated to the latest version, as TLS 1.3 is supported in Windows Server 2019 and higher.To enable TLS 1.3, you can use the Registry Editor on your Windows Server. You will need to navigate to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3 key. If this key does not exist, you can create it.Under the TLS 1.3 key, create a subkey named "Server". Under the Server subkey, create a DWORD value named "Enabled" with a value of 1. The value data type should be set as a DWORD (32-bit) value.Once you have made these changes, you will need to restart your server for the changes to take effect.To verify that TLS 1.3 is enabled, you can use a tool like Wireshark to check the SSL/TLS protocol version used by your Exchange server. Make sure you have captured the network traffic between the client and server, and then filter the packets to show only SSL/TLS packets by using the "ssl" filter. Look for the Server Hello packet, which should contain the protocol version negotiated between the client and server. If TLS 1.3 is enabled, the protocol version should be 0x0304.If you have any other questions or need assistance with anything, please don't hesitate to let me know. I'm here to help.
