Microsoft 365 and standalone business email can both give your company professional email on its own domain. The difference is that Microsoft 365 plans can also include a wider productivity and collaboration ecosystem depending on the plan.

Choose business email when email is the main requirement

If your priority is simply a professional mailbox at your domain, a straightforward business email plan may be enough.

Choose Microsoft 365 when you want a broader productivity suite

Microsoft 365 email can make sense when your business also needs Microsoft productivity applications, calendars, collaboration or cloud-storage features included in the selected plan.

Compare the full plan, not only mailbox price

Storage, apps, user limits and collaboration tools can make a higher-priced plan a better value for some businesses. Review current included features before purchasing.
