After activating Cloudflare, my Outlook email client cannot now connect to my email server.
As per instructions in other support articles, I have set the following DNS records in cloudflare:
A, mail, IPxx.xx.x.xxx, Auto, DNS only (grey cloud)
MX, domain, mail.domain, 10, Auto, DNS only
MX, domain, mail.domain, 20, Auto, DNS only
But my outlook client still cannot connect, any help would be greatly appeciated.
