Delivery Failing to Recipients "Possible Mail Loop"

This question has suggested answer(s) This question has suggested answer(s)

I am setting up 365 and my on premise users started getting all internal email bounced.  The error is "CH1EHSMHS016.bigfish.com #554 5.4.6 Hop count exceeded - possible mail loop ##rfc822".  I have two users on Exchange 365 who don't get this error but anyone who's on our other system is getting this on every internal email (so nothing is getting through).  I changed the MX records back to my old settings and they are working again.  Any ideas what I'm doing wrong?  Please find full message below.  I also noticed the generating server is not my registered name I want to use but the name Microsoft originally assigned.

  • Hi Patrick,

    Thanks for your post. Can you provide more detail information about this case. Based on the information you provided, domain "utdk.com" is not setup MX record of Office365.

    Do you means you have several users and some on Office365 and some on local? if so, you can take a look community.office365.com/.../simple-domain-sharing-for-smtp-email-addresses.aspx

    Thanks, Neo Zhu

  • Neo,

    Thanks for your quick response.  I actually took the utdk.com domain off as the MX Record yesterday in the attempt to get our emails systems functional again.  UTDK was pointing at 365 at the time though.  

  • Hi Patrick,

    Thanks for your reply. Can you provide more detail about the environment? Do you mean all the users are using Exchange online , and the error occur when they send email to each other?

    For the current situation, you have changed-back the MX record the other mail-hosting, can you use another Office365 tenant for testing again?

    Thanks, Neo Zhu
