Microsoft 365 review

Microsoft 365 Business Basic is the entry point to Exchange email on your own domain, and its numbers are generous for the price: Microsoft's US comparison page lists a 100 GB primary mailbox and 1 TB of OneDrive storage per user for $7.00 a month on an annual subscription. The plan includes web and mobile versions of Word, Excel, PowerPoint and Outlook, Microsoft Teams for chat and meetings, and more than 10 extra apps such as Bookings, Planner and Forms, plus automatic spam and malware filtering. A Business Basic plan without Teams is listed at $5.40 for companies that already use another meeting tool. The trade-offs are that desktop Office apps start on the more expensive Business Standard plan, all Business plans stop at 300 users, and the prices shown are for annual commitments. For teams that already send Word and Excel files to clients, it removes the friction of mixing Google and Office formats.
