With Office 365 I have recently set my custom domain up

Hi Readers!

With Office 365 I have recently set my custom domain up. I am able to login to the following http easily.

https://login.microsoftonline.com/common/oauth2/authorize?client_id=00000006-0000-0ff1-ce00-000000000000&response_mode=form_post&response_type=code+id_token&scope=openid+profile&state=OpenIdConnect.AuthenticationProperties%3dV2uztlvwq1Se5M2L-Z8Xy2F8tTea8f2CVIdjqW51EM7q418tY795En1tTpOROa3W825DpFrf5HWSpqu6uhtFb5bjparAyBL5FqYV4h05Jv53qLrwbPqZJ2tro9o4zQp21y8WqdLMRz0Rq3LS14ZgNKpxCYp1fKvHQfb6zYrze989tpaLPIDuf0b3hgIBQWWh&nonce=636509240263957063.NDg5ZWE3YWMtYmIxOC00ZjgwLWFjNDEtOWVlNTAxNGRhODdmMzkzOTlkMDgtNTc4Ny00Mzk4LTkxZDQtNzI0MzM0ODMzNTQ2&redirect_uri=https%3a%2f%2fportal.office.com%2flanding&ui_locales=en-US&mkt=en-US&msafed=0

But with my existing domain name, I have failed in logging in to outlook.com

At the time of logging over the portal page, as I click the point CONNECT OUTLOOK TO THIS ACCOUNT

It informs me of that it can’t find the page. What do you think about this problem?

Do you have any idea, please?
