We migrated from Exchange 2003 to 2010 and are now getting events 5006 and 5020 on the new server.
I thought we had removed everything and uninstalled the old server gracefully but I guess not. I believe the old server is still listed as the routing master or something of that nature, any suggestions how to make exchange 2010 happy and get rid of these events?
Thanks,
Josh
