Deleting an Exchange Connector to solve Event ID 5016

Posted on 2011-09-28

I've been getting an error for a long time in Exchange that I've just been ignoring - now I'm tired of it.  Event Type:      Error
Event Source:      MSExchangeTransport
Event Category:      Routing
Event ID:      5016
Date:            9/28/2011
Time:            3:06:46 PM
User:            N/A
Computer:      OURMAILSERVER
The Active Directory topology service could not discover any route to connector CN=AvExchangeIVC_MAIL,CN=Connections,CN=MYDOMAIN,CN=Routing Groups,CN=BLAHBLAH,CN=Administrative Groups,CN=Our Site Name,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=ourcomany,DC=com in the routing tables with the timestamp 9/28/2011 7:06:46 PM. This connector will not be used.

Regular mail is going out fine and I haven't noticed any real problems.  Using ADSIEDIT and drilling down to Services,,then Connections, I can see the connector in question.  I just see it and our Fax gateway.  Can I safely delete that connector without causing any problems with email?

Here the culprit was connector.
Check connector setting once and make sure thay are optimal.
Also check how many connectors are there.

Check how many connectors are there Under Organization Configuration --> Hub Transport --> Send Connectors

There are three send connectors shown in Organization Configuration, Hub Transport, Send Connectors:
Internet Outboud Email from Exchange HT Role
Kbox Send Connector (which is our Dell KACE management appliance)
XmediusFAX (which is what our fax program uses to send faxes)

All of those look appropriate.

It's been happening since my migration from 2003 - the server has been restarted many times.

This is maximum due to mis-configurations of the connectors, kindly cross check one more time.

I'm not sure what you're asking me to check.  There are three connectors in the Hub Transport.  The one being referenced in the error message is from something we had a long time ago.  Since it doesn't work, I'm just trying to figure out if I can use ADSIEDIT to delete it.

Since it didn't seem that Exchange was using that connector (it referenced a server that did not exist), I went into ADSIEDIT and deleted it.  So far, so goo.  No recurring errors anymore.

Comment from Expert didn't seem to reference my situation.  I found my answer elsewhere on the web.
