    Hi @BRIAN N ,

    As Andy said, you could provide more information so we could better help you out.

    I did a research about the Event 10104 and Event 1024, and they both point to the certificate.
    So please check/test the following:

    1. Is the Edge server also Exchange 2019 CU9?
    2. Are you using a third-party certificate for the mailbox server and edge server?
    3. Have you subscribed Edge to the mailbox server? Procedures for Edge Subscriptions
    4. Run Test-ServiceHealth to test if all services are running.

    Please also find the answer provided by Felix in this thread: EdgeSync Errors and see if it's helpful.

    Best regards,

    Edge server is Exchange 2016 CU20

    third party cert for mailbox only

    All Servers subscribed and 2016 has lease.

    I am going to try building edge as 2019 to see if that helps

    All Services are running
