Telegram works great. Free, privacy friendly, you can create channels (groups), supports bots, super fast with native apps, unlimited cloud storage, unlimited search history and more.

We've been using it for years in our company with excellent results

I don't know why you're getting downvoted, I think Telegram is a valid choice sometimes, expecially if your organization is not that big.

I didn't downvote but for a company-wide tool like that, I'd prefer a solution with a more established legal presence somewhere. Telegram seems more targeted at the consumer space.

Agreed, been using it for 5 years for around 30 of us in 5 to 7 teams. Drag and drop for upload, as well as desktop, mobile and web apps.
