Guest Access in Microsoft Teams is now available

A long-awaited feature for Microsoft Teams has become available by 11 September 2017: Guest access, which allows to add external users that are not part of your organization to participate in chats, join meetings and collaborate on documents in Microsoft Teams.

Teams come in all shapes and sizes, and you need to be able to easily communicate and share with others you want to work with, including people outside your organization. Beginning today, anyone with an Azure Active Directory (Azure AD) account can be added as a guest in Teams. That means anyone with one of the more than 870 million user accounts—across Microsoft commercial cloud services and third-party Azure AD integrated apps—can be added as a guest in Teams. Later, Microsoft will add the ability for anyone with a Microsoft Account (MSA) to be added as a guest in Teams. If the guest doesn’t have an existing MSA, they will be directed to create a free account using their current corporate or consumer email address, such as Outlook.com or Gmail.com.

In Teams, guest accounts are added and securely managed within Azure AD through Azure AD B2B Collaboration. This enables enterprise-grade security, like conditional access policies for guest user access. Azure AD also uses adaptive machine learning algorithms and heuristics to detect anomalies and suspicious incidents, enabling mitigation or remediation actions, such as multi-factor authentication, to be triggered as appropriate. In addition, with Azure AD, IT departments have unparalleled insight into the activities of external users in their organization through detailed sign-in and access reports. Guest user content and activities are under the same compliance and auditing protection as the rest of Office 365.

Guest access in Teams comes with the ability for IT to centrally manage how guests participate within their Office 365 environment, providing consistency across application experiences in Office 365. IT admins can quickly and easily view, add, or revoke a guest’s access to the host tenant.
