guest access

Guest access in Microsoft Teams allows external collaborators to join channels, chat, and share files within an organization's Teams environment. This feature, rolled out in 2017, was part of Microsoft's strategy to expand Teams adoption across businesses, schools, and government departments. By integrating guest access into the existing Office 365 suite, Microsoft made it easier for organizations to collaborate with external partners without requiring them to have a full license. The tag covers discussions about how guest access works, its impact on enterprise collaboration, and its role in Teams' growth to over 125,000 organizations.
