Microsoft has announced that Stream will no longer create a people timeline in new videos it processes after June 1 and that the feature will be retired. The people timeline feature works well for videos taped in controlled conditions, like studios. It is less successful (and useful) for recordings of Teams meetings, which is where a lot of work for Stream comes from currently.
Outlook for iOS finally supports the Do Not Disturb feature to suppress notifications for new email, something that Outlook for Android has been able to do for 18 months. iOS and Android are obviously different ecosystems, so the delay might have been caused by problems dealing with the Apple notification service. In any case, you can now snooze some or all of your email accounts. In other news, some of the more interesting features available to U.S. email accounts are still not available outside the reach of Cortana.
Office 365 supervision policies can now make use of artificial intelligence and machine learning to detect offensive language in email and Teams communications. The data model covers a wide range of problematic language, but only in English. You can go ahead and cheerfully continue to swear in French, German, and other languages with no danger of being detected by policy.
