The challenge with sensitive data and access to Copilot Microsoft 365 Copilot empowers users with AI-driven assistance across Microsoft 365 apps, but it also raises concerns about accidental oversharing of sensitive information.

A couple of favorite news from the world of Teams last week.

Another week has gone by, and it has not been a week without announcements or releases around Teams or Skype for Business. Here is a little recap of what I consider the highlights of last week.

On Teams

If you are into development, Microsoft launched a new site/collection called "What's new for developers in Teams".  And is a great collection and a starting point for developers. https://docs.microsoft.com/en-us/microsoftteams/platform/whats-new

Auto-favorite a channel was released as a feature, allowing admins of Teams to help users mark important channels as favorite. Users may still un-favorite these channels, but this can be a useful feature for new users to different teams.
Other features this week is:
  • Send a message from the command box
  • Send a chat from the contact card

Techsummit in Sweden is over, and one of many great sessions was the one on security and compliance by Anne Michels. here deck is available at the Techcommunity.

On OneNote

The team behind OneNote announced the future of OneNote (as part of Office) and OneNote for Windows 10. https://techcommunity.microsoft.com/t5/Office-365-Blog/The-best-version-of-OneNote-on-Windows/ba-p/183974 
In short terms: If you want all the best and new features, you need to use the "app store" version of OneNote. It is basically replacing the Office version from now on.
