Syncing calendars and contacts with Outlook 365 home

Yes, that's where I started. It's the same procedure as on the Apple support site.

Sign in works, but the credentials fail. The email address I'm using existed before I had Office 365 so it was/is an Outlook.com address.

I got it working. I deleted the Outlook.com type; although I'm thinking maybe I should have left it since it was working after I used iTunes to initially sync. To use the Exchange type I needed to generate a new app password, since Apple Mail does not support 2-factor authentication.

So I sign in with my normal email address and password. Then for (Step 3) I again use my email address but for a password I used the new app password. It works.

Thanks.

After entering my email then password for that account, it indicates my account couldn't be found. And the Domain entry changes from Optional to Required. I tried Microsoft.com and Outlook.com and my password but it the account is not found.

I backed up my phone with iTunes, then tried using the Outlook.com account type. This 'works' but I had many duplicate contacts. I then chose to delete the contacts from my iPhone which it did.

I then added a new contact and edited an existing contact in Outlook 365. It did show up on my iPhone so it seems to be syncing. Still I lost my existing contacts on the iPhone which I can probably restore through iTunes. So the question is why is the Outlook.com account type required and why doesn't the Exchange account type work?

Thanks
