How to resolve 'Selected user account does not exist in tenant and cannot access the application' error?

Question

Hi all,

I have a guest user who experiences the error stating 'Selected user account does not exist in tenant 'Microsoft Services' and cannot access the application in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account.' This error occurs when the user is trying to access SharePoint files that he has been given access to as a guest user.

The user has already been invited as a guest user to the directory. The user has tried to access the file in incognito browser but still faces the error. We have ascertained that the user has been granted access to the SharePoint sites in question. How then do I resolve this problem? Thank you.

Hi @Syed Harith Zaki,

The error usually occurs if the Azure AD Application is registered as Single-Tenant, but other personal account or other tenant users are trying to login.

To resolve the error, try the below:

Create an Azure AD Application as "Accounts in any organizational directory (Any Azure AD directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox)" like below:

For example, you can use below endpoint to authenticate users:

https://login.microsoftonline.com/common/oauth2/v2.0/authorize?
&client_id=ClientID
&response_type=code
&redirect_uri=https://jwt.ms
&response_mode=query
&scope=https://graph.microsoft.com/.default
&state=12345

Also make sure to use common endpoint to authorize the users.

• If you only want only Azure Active Directory users only to login the register the Application as "Accounts in any organizational directory (Any Azure AD directory - Multitenant)" and make use of organizations endpoint.

If the issue still exist, please refer the below MsDoc:

Error AADSTS50020 - User account from identity provider does not exist in tenant - Active Directory
