Solution 1Recommended

Select Cost-Effective Email Plans in the Admin Center

Instead of buying full Microsoft 365 licenses for everyone, purchase cheaper email-only plans like Exchange Online or Microsoft 365 Business Basic for specific divisions.

Microsoft allows businesses to mix and match different subscription plans within the same tenant. For users who only require a business email address without the desktop Office applications, Exchange Online or Business Basic are the most cost-effective choices.

1
Access the Microsoft 365 Admin Center

Log in to the Microsoft 365 admin center using your administrator credentials.

2
Navigate to the Billing Section

On the left-hand navigation menu, click on 'Billing' and then select 'Purchase services'.

3
Find and Compare Plans

Search for 'Exchange Online (Plan 1)' if the user only needs enterprise email, or 'Microsoft 365 Business Basic' if they also need web versions of Word, Excel, and Teams.

4
Purchase the Subscription

Select the desired plan, specify the number of licenses you need for your separate email addresses, and complete the checkout process within your existing tenant.

Mix and Match: You can assign a premium license (like Business Standard) to users who need desktop apps, and an Exchange Online license to users who only need email, all under the same company domain.

Frequently Asked Questions

Can I mix different Microsoft 365 licenses in the same tenant?

Yes, Microsoft allows you to mix and match different plans, such as Microsoft 365 Business Basic, Business Premium, and Exchange Online standalone plans, within a single tenant to suit the specific needs of different users.

Does a global administrator need a paid Microsoft 365 license?

No, a global administrator account does not necessarily require a paid license. If the account is strictly used for administrative tasks in the Microsoft 365 admin center and does not need access to services like a personal mailbox or SharePoint, it can remain unlicensed.

What is the difference between Exchange Online and Microsoft 365 Business Basic?

Exchange Online is a standalone plan that provides only secure enterprise email and calendaring. Microsoft 365 Business Basic includes Exchange email, but also adds Microsoft Teams, OneDrive cloud storage, and web-based versions of Office apps like Word and Excel.
