    Logging into Windows 10 Pro using Office 365 credentials


    Ok, so i've just upgraded from Windows 10 Home to the Pro edition.

    The user account on the PC is currently linked to my MS account. However, this particular PC is for my two part-time workers who I want to be able to login using their 365 credentials.

    I am totally lost?!

    You can follow option 4 here User Account - Add in Windows 10 - Windows 10 Forums and create the 2 accounts on the PC using their email addresses as credentials.

    Thank you. Does that effectively mean they're using their actual 365 accounts to login or will it just create new MS accounts using those same details.

    I do wish somebody could just do this all for me....

    It will use their 365 accounts after you add them to the machine. Once they login, it creates a profile for them. Their credentials will get cached so if there is a time when the internet is down, they would still be able to login. If the internet was down and it was their very first ever attempt to login, it would not work.


    Hope that helps.

    If we are talking about O365 Business or Enterprise accounts, you cannot use these email addresses when creating new users to your computer if the computer has not been joined to Azure AD. If an O365 Business / Enterprise user so wishes, he/she can create a new MS account using the O365 email address as a third party email, but in that case using that account to create a user it would be just a normal MS account.

    A new user must be either a local account or a Microsoft account, O365 Business / Enterprise accounts will not be recognized.

    You don't even have to create user accounts for your coworkers. Here's the correct way to this:

    Sign in to your own admin account. Open Settings > Accounts, select Work access, select Join or leave Azure AD:

    Sign out. Sign in with your own O365 credentials by selecting Other user and entering your O365 / Azure AD credentials and let Windows go through the account initializing process:

    Sign out. As this PC now belongs to an Azure AD domain, your coworkers can sign in without a need to first create user accounts to them. First time they use their O365 credentials, Windows creates the accounts:

    Wow, fantastic!! Two questions:

    1) Once I've added the two part-timers using their 365 Credentials, can I delete the original master MS account so the machine is just left with the two 365 ones?

    2) I use a different machine, I have the Business Premium plan where as the two part-timers just have Business Essentials. Can the two part-timers each use one of my five Office desktop licences?

    I would do it like this:
    • Create a local administrator account, let's say you name it Admin. Be sure it's an administrator account! Give this account a strong password
    • Sign in to that account once to let Windows to initialize the user profile
    • Sign out
    • Use your existing MS account to sign in to Windows 10, join Azure AD
    • Sign out from the MS account
    • Sign in once using your personal O365 / Azure AD credentials, let Windows to initialize the user profile
    • Sign out
    • Sign in to your new local admin account Admin, remove your original MS account
    • Now the machine has for you the local admin account plus your O365 account
    • Let your coworkers sign in with their O365 credentials. Accounts will be created when they sign in first time
    • Anyone wth your organization's O365 credentials can sign in to that PC; when a new user signs in first time the account will be created
    • Notice that these new organisational user accounts are not shown in Welcome screen. A user from your organization wanting to sign in must always first select Other user and then enter full credentials

    No. If the Office suite is installed from your available 5 seats, whoever uses it has full access to your data.

    Sorry to sound slightly dumb but could you elaborate on this please? What kind of data would they have access to?

    The two part-timers only do a few hours each a week so I want to keep costs to a minimum in terms of licencing but I also want them to have their own logins etc so there's some form of separation.

    O365 Business Essentials does not include the Office suite of applications, whereas your personal Business Premium does. As a Business Premium licensee you have right to install Office 2016 Pro on five devices. The validation / licensing is done by you entering your O365 / Azure AD credentials when you launch an Office application first time; you can either activate it with a valid product key or with your O365 credentials.

    If activated using your O365 credentials, all Office applications have now access to your Sharepoint sites and resources including your O365 for Business OneDrive. No credentials will be asked, a user of an Office application when Office is activated with your O365 credentials automatically has the full access.

    An example. The screenshot below shows my Office account settings when I have activated my Office 2016 with O365 Enterprise credentials. It shows me as the user, the O365 licensee who's credentials were used for activation, plus it gives the user access to my OneDrive for Business (#1) and Sharepoint resources (#2):

    What an idiot I am!

    Of course it works as you'd like to. Sorry about me not thinking this through, I have never needed to do this so I assumed too much. My previous post is not accurate.

    Simply when you have joined Azure AD and you have signed in once using your O365 Business Premium credentials, while signed in to that user account install Office 2016 using one of your 5 seats. It will be connected to your account as I mentioned in my previous post, but only when signed in to using your credentials.

    Sign out, let a coworker sign in using his / her credentials. Because the Office 2016 is now installed on the PC and activated with your O365 credentials, any other user on that same PC can also use Office which in their case will by default be not connected to any account. They can then connect Office to their O365 Business Essentials account, even when their O365 license does not include Office suite, because A) Office is already installed on that PC and B) it is activated with your credentials.
