Microsoft Teams Now Lets You Add Guest Users With Any Email


After a couple of delays, Microsoft is finally introducing full guest access support for its Microsoft Teams group-chat service.

Guest support is the ability to add someone outside one’s own organization to a team.

Starting the week of March 5, Microsoft will begin rolling out the ability to add anyone with a business or consumer email address as a guest in Microsoft Teams. (This isn’t just Outlook email; it also includes,, and more.)

Microsoft originally planned to add guest access to Teams by June 2017, but it missed its self-imposed goal. The company added partial guest support — for anyone with an Azure Active Directory account — in September. By late November, officials acknowledged that full guest support was proving more difficult to implement than expected and said full guest support for Teams was still “months” away.

Guest access is included with all Office 365 Business Premium, Office 365 Enterprise, and Office 365 Education subscriptions. Guest access is a tenant-level setting in Teams and is turned off by default.

Microsoft officials said full guest access should start showing up in users’ Teams clients over the next two weeks.
