Enterprise Mobility + Security


Howdy folks,

This is a blog post I’ve been as eager to publish as I suspect you’ve been eager to read it. I’m excited to let you know that Azure AD business-to-business (B2B) collaboration is generally available worldwide!

Azure AD B2B collaboration capabilities enable any organization using Azure AD to work safely and securely with users from any other organization, small or large, with or without Azure AD, & with or without an IT organization.

Organizations using Azure AD can provide their B2B partners access to documents, resources, and applications while maintaining control over corporate data. Developers can use the Azure AD B2B APIs to write applications that bring two organizations together in a secure way that is also seamless and intuitive for end users to navigate.

Customer demand for these capabilities is sky high! Already during the public preview, customers have invited 2.6M guest users using these new capabilities.

And more than 20% of Azure AD Tenants with >10 users are now using Azure AD B2B!:



We have spent thousands and thousands of hours with these customers diving into how we can best serve their needs with Azure AD B2B.

I’d like to thank all of you who spent time with us providing feedback and suggestions. We would not have reached this point without your partnership.
