Removing Send Connector from Exchange 2010 How to Update MX Records

Question

In the past we used a send connector to send to an organization we work with but now that is changing and I have removed the send connector. The problem though is that the MX records do not seem to be updating to the next MX records.

If I do a MXLOOKUP internally it has the wrong information but if I do an MXlookup on mxtoolbox.com it has the correct information.

Any suggestions on updating the internal records?

Please provide nslookup command output. – user5870571 Mar 20 '17 at 17:40 — user5870571, Mar 20 '17 at 17:40

Check your internal DNS, it might be you have configured an "hardcoded" entry with an hardcoded MX record.

Checked that and I am not seeing anything in there for MX in the forward lookup zones – Todd Welch Mar 20 '17 at 17:55
How did you check? Can you edit the results into your question? – chicks Mar 20 '17 at 18:30
