Sharepoint Online going from 10GB to 1TB (+500MB) per tenant

Do you remember Microsoft raised the maximum storage in Sharepoint Online to 1TB last year?

Well, if you look at the Office 365 roadmap, Microsoft has announced it is also increasing the FREE storage each tenant gets by default to 1TB (from 10GB) in Sharepoint Online. The additional SP Online storage per licensed user remains the same at 500MB / user.

That could save us up to 200$ / month 🙂
