You may see the following error:
This account isn’t enabled for SharePoint. Please try again with your work or school account.
You get this if you use an account other than the work or school account given to you.
The SharePoint app is for work and school accounts
You can use the SharePoint app to connect to the following products:
- SharePoint in Microsoft 365 (Enterprise, Education, Government and DvNext).
- SharePoint Server 2013 and SharePoint 2016 also known as the most recent two versions of on-premises SharePoint
To access SharePoint, you need to have an account that’s provided by your organization. We call that a work or school account. A work or school account has a username and password that you created or someone in your organization created for you. For example, if your name was Joe, working for Contoso, your username might be joe@contoso.com
Personal Microsoft accounts
If you try to sign in with another account, maybe a personal Microsoft account, the sign-in won’t work because personal Microsoft accounts don’t have access to SharePoint. A Microsoft account is the email address and password that you may have created yourself. It enables access to free services like OneDrive and Outlook.com. If you bought Microsoft 365 Family, Microsoft 365 Personal or Office Home & Student 2016, you likely created or reused an existing Microsoft account. This type of account is linked to your personal copy of Microsoft 365. You can use any email address to create a Microsoft account. For example, you might have used your outlook.com account, hotmail.com account, Gmail account or another. Example: joe@gmail.com or joe@outlook.com.
More about Microsoft accounts and work and school accounts
The article, Sign in to Office, includes a video and detail on how the two account types can enhance your Microsoft 365 and Microsoft 365 experience.
Where to sign in to Microsoft 365 includes more information on the two account types, including other ways to verify the types of accounts and where they can be used outside of the SharePoint app.
