For collaboration and communication at the workplace, I find that Microsoft Teams does an excellent job. Microsoft has released some new feature updates for the application. Some decent new features are now included by default, and system administrators can have some granular controls for these new features.
New features in Microsoft Teams make it an even more powerful hub for teamwork by enabling you to use apps in new ways—including the ability to command apps and take quick actions from the command box, as well as include content from an app in a conversation. This marks the biggest single release of new functionality since Teams launched last March.
