As of my knowledge cutoff in September 2021, Microsoft 365 Business Basic was a subscription plan offered by Microsoft that provided essential productivity and collaboration tools for businesses. It included cloud-based versions of Microsoft Office applications such as Word, Excel, PowerPoint, and Outlook, which could be accessed through a web browser. The plan also offered business-class email hosting with a 50 GB mailbox per user, along with a custom domain name for the email addresses.
