Read Receipts in Teams
Allow tracking of whether the members of your team have viewed a message that you have posted in Teams, similar to Facebook Messenger/WhatsApp.

This feature is coming soon apparently - https://microsoftteams.uservoice.com/forums/555103-public/suggestions/17042215-need-read-receipts
While some feel such a feature is potentially "intrusive", perhaps its best left to each organisation to decide for themselves, based on their needs and culture,
Organisations wth a large proportion of mobile workers especially may find the feature of greater value. It can be turned off as a default, and activated only when the adminstarators specifically turn it on.
