How to Share Microsoft 365 Family on a Shared PC Without Reinstalling
Question details
The user wants to share a Microsoft 365 Family subscription with a family member on a single shared computer without creating separate Windows accounts.

- Product
- Microsoft 365 Family
- Device & OS
- Windows
- Scenario
- A couple shares a single Windows computer and wants to use a single Microsoft 365 Family subscription under different Microsoft accounts.
- Observed behavior
- The primary owner needs to grant access to the secondary user without reinstalling the software, while ensuring the secondary user can access their own files and benefits on the same Windows profile.
Ensure you have the Microsoft account email address of the family member you want to share the subscription with, and verify that your current Microsoft 365 apps are functioning properly.
Share Subscription and Switch Accounts in Office Apps
The easiest way to use Microsoft 365 Family on a shared computer is by sending an invite to the family member and having them sign into the existing apps.
You do not need to reinstall Microsoft 365. The existing installation on your computer can be used by multiple Microsoft accounts.
However, sharing a single Windows user profile is not highly recommended because it can lead to file confusion. If you proceed, ensure each person signs into the Office apps with their respective accounts when using the PC.
Log into your Microsoft account dashboard, navigate to the 'Services & subscriptions' page, and select 'Share'. Enter your family member's email address to send the invitation.
Have the family member open their email and accept the Microsoft 365 Family invitation using their own Microsoft account.
Open any Office app (such as Word or Excel) on the shared PC, click on the current profile name or icon in the top right corner, and select 'Sign in with a different account'.
Enter the family member's Microsoft account credentials to activate their session and access their personal OneDrive storage.

Frequently Asked Questions
Can two users use the same Microsoft 365 Family subscription on the same computer?
Yes, multiple users can use the same subscription on one computer. Once the primary owner shares the subscription, the secondary user simply needs to sign into the existing Office apps with their own Microsoft account.
Do I need to reinstall Office after accepting a Microsoft 365 Family invite on a shared PC?
No, reinstallation is typically not required. The newly added family member can use the currently installed Office applications by signing into their account within the app.
Why is it recommended to use separate Windows accounts?
Using separate Windows accounts ensures that each user's personal files, OneDrive synchronization, and application settings remain private and do not interfere with each other, preventing accidental data overwriting.
