Solution 1Recommended

Assign an Exchange Online License or Upgrade Your Plan

The most direct way to resolve this issue is by adding a standalone Exchange Online license or switching the user to a plan that inherently includes it.

Microsoft 365 Apps for Business only provides access to desktop apps like Word, Excel, and Outlook. It does not provide the backend email hosting (Exchange Online) required for a Microsoft-hosted email address. You will need to purchase an add-on or upgrade.

1
Access the Admin Center

Log into the Microsoft 365 admin center using your administrator credentials.

2
Purchase the Required License

Navigate to the 'Billing' section and select 'Purchase services'. Search for and purchase an 'Exchange Online Plan 1' license, or choose to upgrade to a comprehensive plan like Microsoft 365 Business Standard.

3
Assign the License to the User

Go to 'Users' > 'Active users'. Select the user experiencing the issue, and click on the 'Licenses and apps' tab.

4
Save Changes

Check the box for the newly acquired Exchange Online license or the upgraded plan, and click 'Save changes' to apply the mailbox access.

Assign an Exchange Online License or Upgrade Your Plan
Propagation Time: It may take up to 24 hours for the new Exchange Online license to fully provision and become accessible for the user.
