Requesting best practice discussion on setting up Teams and Channels
If guest users simply need to access files, you could extend permissions to them to the underlying SharePoint folder associated with the Client Channel.
If guests need to participate via the Teams interface and also have access to Posts, Planner, etc you could make every Client Channel in the Team a Private Channel, then add guests to the Team overall and only to relevant Private Channel(s).
For the second option, it may not be ideal if you're already actively using a Team with Standard Channels, as they can't be converted to Private.
I'd be curious how others have handled this use case.
Hi Todd. Guest users certainly can participate in channels as shown here - https://docs.microsoft.com/en-us/MicrosoftTeams/guest-experience#comparison-of-team-member-and-guest-capabilities
In our setup, if we add a guest to the Production team, they immediately have access to all channels under that team, which gives them access to other client's data, which is what we're trying to avoid.
