I moved off of O365. I am now self hosting my emails with an on premises server. Sending/receiving emails is working perfect. But I can only use the web app. I'm trying to connect Outlook to my personal email server and, everytime I put in my email address, it redirects me to a microsoft login screen. I'm assuming something to do with DNS, but I checked my DNS records and I don't see anything pointing to microsoft servers for that domain.
