Using classic Outlook for Windows in business environments
Natalie,
In Ron's post he linked a website where you could test your domain's DMARC. https://easydmarc.com/tools/dmarc-lookup?domain=goldenstring.com
I found and like the testing tool at https://mx****/dmarc.aspx Using this tool shows your domain does NOT have DMARC published, the DKIM https://mx****/SuperTool.aspx?action=dkim%3agoldenstring.com%3aselector1._domainkey&run=toolpage showed you do NOT have DKIM published for your site. You do have 2 SPF records published. https://mx****/SuperTool.aspx?action=spf%3agoldenstring.com&run=toolpage
spf:goldenstring.com
v=spf1 include:secureserver.net -allv=spf1 include:spf.protection.outlook.com -all
You need to have all 3 SPF, DKIM and DMARC to fix your issue. So to fix your issue follow the steps I listed on Page 8 on another post that I had made. You are in the exact same spot I was yesterday. You are using Wix as your web host and Microsoft Office for your custom domain, which are the same as me. I posted all the steps I did yesterday to fix the issue for my small business.
Cheers,
Theo
