Microsoft is making its Teams business-chat app available for free to entice small and medium-size businesses to try it out.

The free tier will allow up to 300 people to take advantage of many of the paid-for service features, including searching back through messages, in-line translation, audio and video chat, the ability to work with other apps, 10 gigabytes of shared storage and 2 gigabytes of personal storage per person. Microsoft said people can start signing up for the new, free version starting Thursday.
