description: If you have internal user accounts for partners, distributors, suppliers, vendors, and other guests, you can change to Microsoft Entra B2B collaboration by inviting them to sign in with their own external credentials or sign-in. Use either PowerShell or the Microsoft Graph invitation API.

# Customer intent: As an IT admin managing internal guest users, I want to invite them to use B2B collaboration, so that they can sign in using their own identities and credentials, eliminating the need for password maintenance or account lifecycle management.

Before the availability of Microsoft Entra B2B collaboration, organizations could collaborate with distributors, suppliers, vendors, and other guest users by setting up internal credentials for them. If you have internal guest users like these, you can invite them to use B2B collaboration instead. These B2B guest users are able to sign in using their own identities and credentials, eliminating the need for password maintenance or account lifecycle management.
Sending an invitation to an existing internal account lets you retain that user’s object ID, User Principal Name (UPN), group memberships, and app assignments. You don’t need to manually delete and reinvite the user or reassign resources. To invite the user, you use the invitation API to pass both the internal user object and the guest user’s email address along with the invitation. When the user accepts the invitation, the B2B service changes the existing internal user object to a B2B user. Going forward, the user must sign in to cloud resources services using their B2B credentials.
## Things to consider
1. Find the user in the list or use the search box. Then select the user.
1. In the **Overview** tab, under **My Feed**, select **Convert to external user**.
