Microsoft Loop IT governance and management controls

Hi Serge, thanks for your question. I'll answer in two parts:

1. When will Loop support guest access / external sharing?

This is available today for companies that do not use sensitivity labels. For companies that use labels, support for sensitivity labels on Workspaces is coming very soon (in the coming weeks). Once available, you will be able to collaborate with guests.

2. Can you share externally when we apply sensitivity labels?

This depends on the label. The label will determine who you can share with, whether the file is encrypted, etc. Just like how it behaves for Word, Excel, PowerPoint files.
