Started a new company and needed mail/document hosting and went with what I know - Microsoft 365 and found the Business Essentials (or Business Basic now) is free for 6 months if you sign up for 12 months, saving $41.40 per user per year. I already have Office 365 Home and Business so Business Basic is perfect, gives me full Microsoft 365 mail, Sharepoint, Teams, 1TB of OneDrive, all the office web apps, just not a licence to download the regular applications. Good deal if you're after this product.
FAQ states billing will occur on the 7th month and can cancel at any time.
Do you get it if you're a customer for 5 years on essentials?
