Fix Microsoft 365 Installation Problems with Multiple Accounts
Question details
The user is experiencing installation conflicts with Microsoft 365 because multiple Microsoft accounts or trial versions are linked to the same device.

- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Installing or activating Microsoft 365 on a device where multiple Microsoft accounts have been used or trial versions are present.
- Observed behavior
- The active subscription is not recognized, or the system defaults to a trial version, preventing successful installation and activation of the paid software.
Make sure you have your Microsoft account login credentials ready and close any currently open Office applications before troubleshooting the installation.
Identify the Correct Account and Reinstall Microsoft 365
Locate the account with the active subscription, remove any conflicting trial versions, and perform a fresh installation.
Having multiple Microsoft accounts signed into one device can confuse the Office installer. You must clear out old trial versions and ensure you are downloading the software directly from the account that holds the active license.
Open your web browser and navigate to the Microsoft Services and subscriptions page. Sign in with your primary Microsoft account to verify if it holds the active Microsoft 365 license.
Open the Control Panel or system Settings on your device. Go to the 'Programs' or 'Apps' section, locate any existing Microsoft Office trial versions or older installations, and select 'Uninstall'.
Return to the Services and subscriptions page while signed into the correct account. Click the 'Install Office' button and follow the on-screen prompts to complete a clean installation.

Contact Microsoft Support for Unrecognized Subscriptions
If you cannot find your active subscription on any of your accounts, you will need to verify your purchase directly with Microsoft.

Frequently Asked Questions
Can I merge two Microsoft accounts if I bought Microsoft 365 on the wrong one?
No, Microsoft accounts and their associated subscriptions cannot be merged. You must sign in using the specific account that holds the active license to install and activate your software.
Why does my computer keep opening a trial version of Office instead of my paid Microsoft 365?
This usually happens when a pre-installed trial version was not removed before installing your paid subscription. You need to completely uninstall the trial version from your system settings and then reinstall Microsoft 365 from your active account.
What should I do if the Microsoft Services and subscriptions page says I don't have a subscription?
First, ensure you are signed in with the exact email address used for the original purchase. If the subscription still does not appear, contact Microsoft Support with your proof of purchase so they can help locate the correct account.
