To collaborate in Microsoft Teams between Ithaca/Cornell Tech, Weill Cornell Medicine (WCM), and WCM-Qatar, create a shared channel. Doing so will allow participants to interact while staying in their familiar Teams setup, without needing to switch accounts.
 
To get started, a team owner should create a shared channel with themself as the channel owner and their team as the host team. The channel can be shared with as many or few of the host team as you like and also include individuals who are not part of the host team. This feature is particularly beneficial for projects that require external collaboration.
 
Channel owners can then add participants using their full email addresses (for example, @cornell.edu addresses for Ithaca and Cornell Tech members, @med.cornell.edu addresses for WCM members, and @qatar-med.cornell.edu for WCM-Qatar members).
 
When using shared channels across campuses, do not use the default General channel for intercampus conversation. It cannot be shared, so the part of the group that is outside the host team will not see it. For suggestions about what to do with the General channel so cross-campus conversation is not posted there, see "The General channel is not shared" on Create Shared Teams Channels Between Ithaca and Cornell Tech, Weill Cornell Medicine (WCM), and WCM-Qatar.
 
Shared channels offer a platform where conversations are open to all members, regardless of location, while restricting individuals who are not part of the host team to specific channels they have been invited to. The shared channel essentially works like a team within a team.
