新機能：TeamsへのGmailアドレスによるゲストアクセス

Guest Access in Teams is expanding to natively support Google accounts.

• We’ll be gradually rolling this out to Teams customers in early November.
• The rollout will be completed worldwide by mid-December.

How does this affect me?

Azure AD is adding support for Google as an Identity Provider for B2B Guest scenarios (currently in Preview).

Guest users with a Gmail address can now use their Google account credentials to access your organization’s teams content if your IT department has enabled the feature in Azure AD.

Once enabled, new users who are invited to your tenant with a Gmail email address will be able to redeem the invitation and sign in to Teams without creating a personal Microsoft account. Guest users who try to sign in to Teams directly, instead of following a tenanted link, may be asked to first roundtrip a code to their Gmail address and then sign-in to your tenant with their Google account credentials.

• There is no impact to existing Guest users who had already been invited to your organization with a Gmail and created a personal Microsoft account at the time.
• There is also no impact if your organization has not enabled the Azure AD feature.

What do I need to do to prepare for this change?

To allow future Guests users to access your organization’s Teams content with their Google account credentials, your organization needs to enable Google as an Identity Provider for Guest access for your tenant.
