Hi, I'm getting this error when trying to set up AAD Connect.

What's the solution to this problem?

Windows Server 2016, fully updated.

Microsoft Edge is installed, set as default browser and yet it won't work.

Thank you.

It is great that you are able to resolve the issue.

Since the Microsoft Q&A community has a policy that "[The question author cannot accept their own answer.

You logged in to Edge browser with your global admin credentials. Post that you came back to AD connect and got the MFA satisfied by using an alternate method.

Above was a work around. You can also try below approach to fix this as well,

Browse to URL mysignins.microsoft.com, then logging on with your account in question. Once logged on, you will notice a validation page where you will have to click OK on. It will be something like a verification for your MFA configuration. Once you click OK, you will then able to go back and log on with this account.

Let me know if this helps.

Is the Azure account you are using MFA enabled?

Can you exclude it temporarily for the install if upgrading the browser is not a fix?

It's not the perfect solution, although how would I disable it temporarily for this account only?

Thank you.

if using a conditional access policy or per user, you can exclude that way or add the internal LAN as a trusted location in a CA policy and not require MFA.. If not, then you would need to look at upgrading that browser on the server.

I opened Edge and signed into Azure with the admin account successfully.

Then I went back to Azure AD Connect and used the number matching instead of text code and it logged in fine.
