Microsoft 365 Bus Standard

Microsoft 365 Business Standard purchased through Dell must be activated and assigned to a Microsoft 365 work account; it cannot activate Outlook using only a personal Microsoft account.

Complete the Dell business-account activation

1. Search your email, including junk mail, for these Dell messages:
   • “ACTION REQUIRED to Complete Your Dell Order … for Microsoft 365”
   • The Microsoft 365 Welcome email from Dell.
2. Open the Microsoft Domain Details link in the “Action Required” message and complete the tenant/domain setup. If you do not have a custom business domain, the setup can use an onmicrosoft.com tenant domain.
3. Follow the Welcome email to finish activation in Dell My Account/Customer Portal. Use the username supplied in that email—not your personal Microsoft account. Dell documents this activation process for Business Standard and Business Premium purchased through Dell.^1^
4. Open Word or Excel and select File → Account:
   • Sign out of the personal account shown under the product/license information.
   • Sign in with the new Dell-provisioned work account.
5. Close all Office applications, restart Outlook, and sign in with that work account when activation is requested.

Business Standard licenses are assigned to users created within the business organization, and those users install and activate the desktop applications with their work accounts.^2^

Add your personal mailbox afterward

After Outlook is activated by the licensed work account, add your personal Outlook mailbox separately through Outlook → File → Add Account.

Microsoft lists Business Standard as a desktop-app license for a work account, while Microsoft 365 Personal and Family provide desktop licensing for a personal Microsoft account. Outlook permits personal accounts as secondary accounts once an account with a qualifying desktop-app license has been added.^3^

If the Dell activation was already completed

If Dell supplied a work username and the license still appears expired:

1. Sign in to an Office application with that exact work username.
2. Check File → Account for an Update License option and select it.
3. On Windows 10 or later, run the Microsoft 365 activation troubleshooter on the affected PC. Microsoft also recommends checking for multiple Office installations because conflicting copies can prevent activation.^4^
4. If the Dell Welcome email is missing, or no work account/license was created, contact Microsoft 365 from Dell support. Dell’s support library provides the reseller-specific support path.^5^

Do not purchase another subscription until Dell confirms whether the existing Business Standard seat has been provisioned and which work username owns it.
