Office 365 Teams support
O365 Teams has apps: I can pin the app (or rather the file which is editable by the app) to my Team's channel and that has two consequences:
- access rights: only the team members have access to the file
- organisation/discovers ity: all documents related to the channel (in most cases channel is a project or customer) regardless of type are in one place
Definitely need a way to limit access to only team members.
