Solution 1Recommended

Assign an Exchange Online License to the User

The standard way for a user to access their own mailbox and sign in to Outlook is by assigning them a valid Microsoft 365 or Exchange Online license.

Without an active license, a standard user account cannot access webmail or desktop email clients. Assigning an eligible license provisions the mailbox and enables normal sign-in capabilities.

1
Log in to Admin Center

Go to the Microsoft 365 admin center and log in with your administrator credentials.

2
Navigate to Active Users

In the left-hand navigation menu, select 'Users' and then click on 'Active users'.

3
Select the Unlicensed User

Find and click on the unlicensed user account that needs email access.

4
Assign the License

In the user pane, go to the 'Licenses and apps' tab, check the box for an Exchange Online or eligible Microsoft 365 license, and click 'Save changes'.

Assign an Exchange Online License to the User
Provisioning Time: It may take up to 30 minutes for the new mailbox to fully provision and become accessible to the user.

Frequently Asked Questions

Can an unlicensed user log in to Outlook on the web?

No. An unlicensed Microsoft 365 user cannot sign in to Outlook on the web or use any Microsoft 365 applications directly. They must be assigned a license that includes Exchange Online to authenticate.

Do shared mailboxes require a paid Microsoft 365 license?

Generally, shared mailboxes with a capacity of up to 50 GB do not require a separate license. However, every user who accesses the shared mailbox must have their own valid Microsoft 365 license.

How do I access a shared mailbox?

A licensed user with delegated 'Read and manage' or 'Send as' permissions can open the shared mailbox within their own Outlook desktop client or by adding a shared folder in Outlook on the web.

Can I forward emails from an unlicensed user account?

Mail forwarding requires an active, provisioned mailbox. If the user account is unlicensed, the mailbox is typically disabled or deleted, meaning email forwarding will not work unless the address is converted to a shared mailbox or a mail contact.
