Microsoft Teams Connect aka Shared Channels Coming Later in 2021
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.
