Using classic Outlook for Windows in business environments
Lordslipgate's posted a great fix. Here it is. First uninstall Outlook THIS WORKS!!!!! It worked great!!! Go to (Github) sign up, look for the item )repo:matej137/OutlookRemover the button says code) download it, extract it then run the bat code as a administrator. The change to outlook prompt still shows up when you open Mail. Clicking on dismiss or allow but nothing will happen. (Thank the Lord).
Outlook's font is too small and you're looking at all the accounts. I have 4 hotmail accounts and Mail is so much better for my eyes to work and see one account at a time.
Really you can download the .zip and save it. When the .NetFramework upgraded the other day I just extracted the OutlookRemover-main.zip file again and ran the .bat file again as a administrator and I have the old Mail again. So hold onto the file.
