Office 365 Enterprise.
E3 (Businesses that need to project a professional image with email and file-sharing tied to a custom domain, as well as those who have to comply with industry-specific regulatory requirements.)
Microsoft offers a dizzying menu of options for its enterprise customers, including Office 365 ProPlus ($12 a month), which includes just the desktop programs and OneDrive for Business storage, as well as the Office 365 Enterprise E3 and E5 packages, which bundle online services with those apps.
Although these plans are intended primarily for large corporations, they might make sense for a small business such as a law office or health services consultant that has to comply with industry-specific regulations such as HIPAA. In addition to the services included with a Business Premium plan, the $20-a-month Enterprise E3 plan offers security and compliance tools, such as the ability to place a legal hold on an email account and data loss prevention tools.
An Enterprise subscription also future-proofs your growing business. Unlike the Business Premium plan, which limits the total number of users to 300, you can purchase an unlimited number of enterprise licenses and mix and match the ProPlus, E1, E3 and E5 plans. Here, too, the management interface can be daunting and is best left to a professional consultant or a managed service provider.
