External Sharing in SharePoint and OneDrive is changing: What You Need to Know

In an ongoing effort to create a more secure environment by default, Microsoft is introducing an important security update that will affect how external users access content shared through SharePoint and OneDrive.

Download participant list from Teams meetings

You will soon be able to download a participant list from within your Microsoft Teams meetings. This feature can be helpful to identify who attended a mandatory meeting, but also useful as a tool to identify users with connection problems. Multiple drops and reconnects can be a sign of network issues.
The feature is not enabled by default, and will have to be enabled by an admin with the following command: 
  • Set-CSTeamsMeetingPolicy - Identity Global - AllowEngagementReport "Enabled"
If you want to limit the availability of this feature, you will have to create a separate meeting policy, assign that policy to the users and then scope the above command to that policy.
This feature is available only from within a meeting, and should be rolling out already (early may, according to the admin message center).
