EventID: 5038, Source: MSExchangeFrontEndTransport Cannot find Routing Destination and Delivery Group for database Public Folders in routing tables with timestamp . Routing will try to find another proxy destination.

Migration from 2007 to 2013.  Performed all the steps required per technet.microsoft.com/en-us/library/jj898581(v=exchg.150).aspx.  Exchange 2007 has been completely removed from the organization.  Still getting many of these errors although public folders are working perfectly (i.e. mail is flowing to the public folders without bounces or any issues at all).  Any thoughts on how to get these event log errors to stop?

Thanks,

Paul
