You can also add guest accounts in Azure AD using Azure AD B2B. Azure AD B2B is a feature on top of Azure AD that allows organizations to work safely with external users. To be added to Azure B2B, external users don't need to have a Microsoft work or personal account that has been added to an existing Azure AD tenant. All sorts of accounts can be added to Azure B2B.

You don't have to configure anything in the Azure portal to use B2B; this feature is enabled by default for all Azure AD tenants. Perform the following steps to do this:

1. Adding guest accounts to your Azure AD tenant is similar to adding internal users to your tenant. When you go to the user's overview blade, you can choose + New guest user from the top menu, as follows:

2. Then, you can provide the same credentials as an internal user. You need to provide a name and an email address, as well as a personal message, which is sent to the user's inbox. This personal message includes a link so that you can log in to your tenant. You can also add the user to a group, as well as an RBAC role:

3. Click Invite to add the user to your Azure AD tenant and send out the invitation to the user's inbox.
4. To manage external users after creation, you can select them from the user overview blade. They will have a USER TYPE of Guest. Simply select the user from the list. Now, you'll be able to manage the settings that are displayed in the top menu for this user, as follows:
