Limit access to guest members
MagnusGoksoyrOLDProfile I do not think this will help me. My teams are all private and will always be. It's not a matter of how to discover a team or how to invite a guest, it's a matter of distinguish a team member based on his "domain": if he is mike@mycompany.com it should have regular members permission, if he is mike@customercompany.com he should have another set of permission, because he is actually a team member but is a "guest" member.
mauros801 The only possible solution that i can think of is using Azure Information Protection and to use a group containing "Internals" and protect files based on that. However You will not be able to protect the conversations in the channels.

MagnusGoksoyrOLDProfile I got your point, but I think it will only block guests from opening some labeled files, not to browse the folder tree.
