- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Managing Microsoft 365 tenant licenses and permissions for external partners or guest users.
- Observed behavior
- Guest access to desktop Office installation and activation is restricted unless properly configured through specific tenant administration and license assignments.
Ensure you have global administrator or billing administrator privileges in your Microsoft 365 admin center to invite guest users and assign available licenses.
Add the External User to Your Tenant and Assign a License
To grant desktop app access, the external user must be officially added as a guest in your organization's directory and assigned a license that includes desktop apps.
By default, external users only have access to shared resources via the web. To allow them to download and activate the desktop versions of Word, Excel, and PowerPoint, you must consume one of your organization's paid licenses and assign it to their guest account.
Go to the Microsoft 365 admin center, navigate to 'Users' > 'Guest users', and select 'Add a guest user'. Follow the prompts to send an invitation to their external email address.
Once the user accepts the invitation, go to 'Users' > 'Active users'. Select the guest user's name, click on the 'Licenses and apps' tab, check the box for an eligible subscription (e.g., Microsoft 365 Business Standard or E3), and click 'Save changes'.
Instruct the external user to log in to Office.com using the guest account credentials associated with your tenant. From the dashboard, they can click 'Install Office' to download the desktop applications.
After installation, the user must open any Office app (like Word) and sign in with the exact guest account credentials to activate the Microsoft 365 license.

Frequently Asked Questions
Can guest users use Office for the web without a paid license?
Yes, external users can collaborate on shared documents using Office for the web (Word, Excel, PowerPoint online) for free, provided your tenant's external sharing settings allow guest access. Desktop activation, however, requires a paid license.
What Microsoft 365 licenses include desktop apps for external users?
Licenses such as Microsoft 365 Business Standard, Business Premium, E3, or E5 include the desktop versions of Office apps. Basic or web-only licenses (like Business Basic) do not allow desktop activation.
Why is the guest user unable to activate Microsoft 365 after downloading?
The guest user must ensure they are signing into the Microsoft 365 desktop apps using the exact guest account credentials that were invited to your tenant and assigned the license, rather than their personal or primary business account.
