Work with guests in Microsoft Teams—We’re rolling out the ability to add anyone as a guest in Microsoft Teams. Previously, only those with an Azure Active Directory (Azure AD) account could be added as a guest. Starting next week, anyone with a business or consumer email address—including Outlook.com and Gmail.com—can participate as a guest in Teams with full access to team chats, meetings, and files. Guests in Teams will continue to be covered by the same compliance and auditing protection afforded to Office 365 subscribers, and can be managed securely within Azure AD.
Enforce naming conventions across Office 365 Groups—We introduced the ability for administrators to set naming policies for Office 365 Groups. This top requested feature allows organizations to enforce consistent naming structures and block specific words from being used. Naming policies are automatically applied when a user creates a new group, and can include dynamic attributes from Azure AD, such as department, office, or geographic region. This makes it easier for administrators to manage groups at scale, and for users to identify relevant Office 365 Groups in the global address list.
