A year after announcing Teams shared channels, Microsoft is preparing to release the code into public preview in March 2022. The new collaboration mechanism uses Azure AD B2B Direct Connect instead of guest accounts, meaning that external members of shared channels use credentials issued by their home tenant to gain access. You’ll need to configure a cross-tenant access policy to allow shared channels to work externally. Once that’s done, the collaboration floodgates open.
Teams Connect is coming in early 2022 and there’s a lot of buzz about how this will help people work together seamlessly. For larger organizations who need to work together, but can’t migrate to a single tenant, could this new functionality enable their plans to migrate?
Microsoft Teams Connect, a new way of collaboration based on federated shared channels, is now in private preview and should be available later in 2021. The best thing about shared channels is that you don’t need to switch tenants to access a channel in another tenant. Azure B2B collaboration (guest accounts) is still important, but this is a brand new way of working that should be very popular.
