The short answer
Yes. Rebuilt or re-downloaded automatically when needed.
What is it?
The cache of the new Microsoft Teams app inside its sandbox container: web content, images and app resources.
What happens if you delete it?
Teams downloads what it needs again, so the first launch after clearing is slower. Chats, files and meetings are kept in Microsoft’s cloud.
How to remove it properly
Quit Teams completely, then move ~/Library/Containers/com.microsoft.teams2/Data/Library/Caches to the Trash. Microsoft also suggests clearing the Teams cache as a troubleshooting step.
Quit the app that uses it, then move it to the Trash. Empty the Trash when you’re sure.
