i had this problem also today. a quick chat with the support team and they fixed it in 2 minutes!
Adding on because I just went through this and chatted with support. Note: This was for Zoho after verifying DNS in Shopify.
I’d reached this section and the MX files were producing errors.
Go to DOMAINS >> your main shop >> scroll down to EMAIL FORWARDING and click “switch to email hosting”.
Select “Zoho Mail” and from that initial TXT code used to verify your DNS, only the section of your verification that I made bold/red below.
zoho-verification=zbxxxxxxx.zmverify.zoho.com
That should be accepted.
Go back to the DNS management page and add the remaining TXT files on the Zoho list.
Click “verify” in Zoho.
Has anyone figured this out? Having the same problem.
Having the same issue and have not been able to get in contact with any of the staff. If someone could reach out to me and help that would be great.
It took me three tries, but when I finally got ahold of someone on the live chat, they fixed it in five minutes.
It worked, thank you
