Message says "The Microsoft account doesn't exist. Enter a different account or get a new one."

After having a Conversation with Microsoft it worked for 2Hours again and after the Next Day never since.

The weird thing is all other 365 Apps and the Account including the Windows License are working except Outlook.

So i canceled the 365 Abo Today as i can use another E-Mail Client for this and use Open Office instead for free.

On Mac there is no Problem with that in Outlook but i am p o. anyway. After having this Setup working for Years it just stopped Working. Get yourself together Microsoft.

It is true: Microsoft is a Time Killer, i am switching to Mac completely.

Bye

Guess what ;-)

After getting through the Options i walked over the Options Privacy in the General Options and deactivated Connected Experience witch is in General a logging function as it Reads all your Text and send it to MS ?

After deactivating that Option without knowing it´s existence i got rid of that annoying behavior.

So Microsoft is logging your E-Mail Messages by default without mentioning it and to make it worth, then f up their own Program with this?

DA BS

I believe the issue here is that you're trying to sign in with a work (not personal) Microsoft account. Before you can sign into a device using a work Microsoft account, you first have to join the computer to the Azure Active Directory. Settings -> Accounts -> Access Work or School -> Connect -> (on the bottom) Join this device to Assure Active Directory, sign in with a Global Admin account. Now you can sign in with a work MS account!

Like others have said do not use internet when setting up the computer initially. If you already connected try turning off your wireless router or force restart the PC by holding down the power button.

So I went through the motions with Microsoft Support

In my case I was trying to get the user to log into their PC using their Microsoft account and not a local account.

The situation was actually very simple. You simply choose other user and enter the person's Microsoft 365 credentials directly on the login screen!
This worked first time

Next step is to then create another local account
Log in with that one
Then do a profile move

To move the user settings and file from one account to another;

1. Go to Control panel> System> Advanced system settings. Click on the Settings button under user profiles
2. Select the user account from which you want to copy the settings
3. Click Copy to, and then enter the name of, or browse to, the profile you want to overwrite. This will usually be in C:\Users\username, where username is the name of the profile to which you are copying.
4. Click Permitted to use, and then add all user accounts to which you want to give full profile control.
5. Click OK.

I haven't done the profile move yet but I know it does work from past experience.

Not sure why you can't just add the account. I was informed by Microsoft to confirm if the machine was AzureAD joined but I think that's a different scenario.

Hopefully this solves the issue for others!

This is madness, I enter an email address and the setup says that the account does not exist, so I click on "create a new one" which takes me to the create account screen with the email address pre populated where it then says that the account already exists and I should use it to log in !! Madness.

Anyway, the shortcut to making a local login is to use Shift-F10 to get to the command prompt and there issue an ipconfig /release which will disconnect the device from the network. Then when you go back to the MS login screen and hit the back arrow it goes to the local account creation screen.
