a customer was running SBS2008, which I migrated to Exchange 2013. The old SBS was deinstalled, demoted and removed from the domain. This was about two months ago.
Recently I installed a new firewall system (Sophos sg) with an SMTP proxy that receives and scans and forwards all mail. I am finding in it's queue many messages going from NO SENDER to inboundproxy@contoso.com.
The log sais this:

Hi,
Exchange 2013 is using Health mailbox for health monitoring, and they are located in AD/Microsoft Exchange System Objects/ Monitoring mailboxes.
Do you have them in there? Maybe something went wrong with them, and they are deleted or something.
They can be recreated, but before doing that, maybe check to see if they do actually exist on your server.
Regards,
Ivan.
