Getting My G Suite Email To Work With Outlook 365

As the title suggests, I'm struggling to get my outlook 365 to work with my G Suite gmail account.

I started a small service business 2 years ago and have got to the point where I am doing well but want to grow things. I have been managing with my free gmail account but want to present a more professional image so I went and registered a domain name and signed up for G Suite so that I have an @businessname email address.

I have set it up fine with the domain and can send and receive emails through the webmail thing but I want to be able to do it through my Outlook 365. I am so used to using Outlook that I get annoyed at other client software, plus I paid for 365 so that's another reason I want to use it.

I had zero problems setting up my free gmail account with outlook but I can't figure out this paid version of it. I enter my email address and password in the Auto-Configure part and it finds the account settings and then asks me for username and password again.

The server name is the domain host I bought my domain registration from and I have tried, for user name and password, my g suite details and my domain host details but neither work. I have tried setting up the IMAP myself using the details in my DNS management settings and that seems to cause outlook to have a seizure and stop working.

I have tried googling for answers but I feel like I'm fumbling around in the dark here. Any and all help will be appreciated greatly
