April 12th Is your deadline for the emergence of the new Microsoft teams (free) Is from Microsoft. If you currently using the previous version you are going to find out that there is no automatic data transfer path between the two applications.

To see the new changes on this support page about the retirement of Microsoft Teams Free, now called Microsoft Teams Free (classic).
Microsoft's product page positions the new Microsoft Teams (free) tier as a product for home users and families, but the features it offers are pretty similar to the old classic tier overall. Video calls still top out at 100 participants and a one-hour runtime (one-on-one meetings can run for up to 30 hours). Each Teams (free) user gets 5GB of storage, while Teams Free (classic) users received 2GB each and a 10GB pool of shared storage. Both products offer unlimited chatting and access to shared files, task lists, and polls.
