My company has MIcrosoft 365 business plan with multiple licenses: I cannot use license b/c my email is with personal account

Your Microsoft 365 administrator must create and license a separate work or school account for you using the company-domain address; the existing personal Microsoft account does not need to be deleted.

Personal Microsoft accounts and organizational work accounts are separate identity types. They may use the same email address, but they are not synchronized and have separate passwords and account settings.^1^

Steps for your Microsoft 365 administrator

The administrator—not the employee—creates the business account:

1. Sign in to the Microsoft 365 admin center.
2. In Dashboard view, go to Users → Active users → Add a user.
   In Simplified view, select Add user.
3. Enter your name and set the username to your company address, such as [Email], by selecting the company domain from the Domains list.
4. Create or automatically generate a temporary password.
5. Under Assign product licenses:
   • Select the employee’s country or region.
   • Select the appropriate Microsoft 365 Business license.
   • Leave the required apps enabled.
6. Select Finish adding.
7. Securely provide the new username and temporary password to the employee.

Creating the account and assigning its license are both required before it can access the organization’s Microsoft 365 services.^2^

If your address already appears under Users → Active users, the administrator should open that existing organizational user and assign the available license rather than create another user.

Sign in with the new business account

After the administrator confirms that the account and license are ready:

1. Open a private or incognito browser window to avoid automatically reusing the personal session.
2. Go to Microsoft 365 and select Sign in.
3. Enter the company email address and the temporary password supplied by the administrator.
4. If prompted to choose an account type, select Work or school account, not Personal account.
5. Change the temporary password and complete any multifactor-authentication registration requested by the company.
6. To activate the desktop applications on Windows, open Word or Excel and select File → Account → Sign In, then use the work-account credentials.[^3^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Sign in to Microsoft 365")

If the administrator cannot select bridgeportllc.com

The administrator should verify that the company domain is available in the organization’s Microsoft 365 tenant. Until the custom domain is configured, the administrator can create the account using the tenant’s provided onmicrosoft.com address. Microsoft 365 business tenants initially receive an onmicrosoft.com domain and can subsequently add their own custom domain.^1^

Do not redeem the business license through the existing personal account. The license must be assigned to the organizational user by a User Administrator or License Administrator.
