Over three years ago my company changed to a new domain name. Until recently, we paid to keep the old domain active while people updated their records. When the renewal came up the partners decided to not renew the old one.

So just recently, a number of regular contacts have had issues emailing some of my coworkers. They have sent some bounced email messages to us, and it shows:

The email address displays correctly (e.g., rock.shale@slaterock.com)

But in the data dump below, it shows the email is still being sent through the obsolete server (e.g., srg.com). Our IT folks did a thorough check to see if the problem could be on our end, but they can't find anything.

We have advised they delete the person's contact and make a new one, and then delete the 'autocomplete' prompt that comes up when starting to type Rock Shale's contact info. (Sorry for the Flintstones-themed examples.) One of our clients says she tried that, but when Emailing my coworker and copying me (someone she didn't have in her contacts), it came through to me and not to him again. Maybe she missed a step... but is there any other trick here? I'm not sure how the new email address would trigger the old domain.

Unfortunately, we can't control what someone outside our company is doing, but I'd like to be able to give a clearer direction. It's only a few instances from a few people. One client can email our president, but not another of the senior people - it may be because they created a new contact for the president after the domain name change?

Thanks for any ideas.
