Problem

Background: Just introduced Exchange 2016 into Exchange 2013 Environment. Mailboxes on Exchange 2016, can send external mail and internal (to Exchange 2013) mail. No mail flows from Exchange 2013 to Exchange 2016. External mail to Exchange 2016, (which flows thought the 2013 server,) also fails.

Event ID 5006

Cannot find information about owning Mailbox Server {server-path} for database {database-path} in routing tables with timestamp {time-stamp}. Recipients will not be routed to this database.

Event ID 5015

Microsoft Exchange cannot find a route to the source transport server or home MTA server {server-path} for connector {connector-path}  in routing tables with timestamp {time-stamp}. Microsoft Exchange is ignoring the source transport server.

Solution

Oh I struggled with this for hours! I removed and recreated the receive connectors, on the Exchange 2016 Server. I went though ADSIEdit and checked all the databases, servers and connectors had inheritable permissions, and that the Exchange Server group had the right permissions. I restarted the transport services, and rebooted the Exchange 2016 server.

I was about 7 pages deep in Google translating Spanish and Russian tech posts, when I started to think I might have to ring Microsoft. When I stumbled on a Technet post that had the same Event IDs I posted above.

ANNOYINGLY: The fix is to reboot the 2013 Exchange server! (So I had to plan in some downtime). I was a bit skeptical this would work, and it did take a few minutes, I watched the ‘Undeliverable Queue’ change and the mail get delivered.

Thank you EngineerBoy wherever you are!
