after upgrading exchange 2013 to latest CU we are getting a large number of Undeliverable inbound proxy probe emails coming from the postmaster@keyman .com going to the healthmailbox and getting "delivery has failed to these recipients or groups"

What is this and How can i provide resolution.

    You can delete them all with powershell:
    Get-Mailbox -Monitoring | Remove-Mailbox

    Make sure you also read this and give the necessary permissions so the AD objects are removed:
    https://learn.microsoft.com/en-us/exchange/troubleshoot/administration/remove-mailboxdatabase-cannot-remove-health-mailboxes

    Otherwise, remove the AD objects manually

    Then restart the Microsoft Exchange Health Manager, MSExchangeHM service on each Exch server to recreate them.

    There is NO danger in doing this. It can be done anytime.

    what about just creating the postmaster@keyman .com mailbox . Would that work as well?

    Which solution is better?

    it's annoying for 1 specific user who is getting them . they seem to be forwarding to a specific user 's mailbox? Is this possible?

    Where would i verify if/how this forwarding is taking place..
