Good morning @MrJeff!
This definitely sounds like a scam to me too. We would never advise that our customers keep the same password upon expiry. Check the header and the senders email and share those here, please!
Please forward the email to email@example.com, include a brief description of the issue and copy/paste the full email headers above the body of the forwarded email.
If you ever receive suspicious email, please always remember to forward it to us so that we can directly combat this spam on our network using your sent examples. 🙂
