Fix Microsoft 365 Installed But Office 2019 Still Opens on Mac
Question details
The user installed Microsoft 365 on their Mac, but previously installed Office 2019 applications continue to launch instead of the newly installed Microsoft 365 versions.
- Product
- Microsoft 365 / Office 2019
- Device & OS
- macOS Sonoma
- Scenario
- Upgrading from an older perpetual license (Office 2019) to a subscription-based Microsoft 365 on Mac.
- Observed behavior
- The Microsoft 365 applications do not appear visible as expected, and launching Word continues to open the legacy Office 2019 version.
Ensure you have the correct Microsoft account login credentials associated with your active Microsoft 365 subscription before clearing your previous software licenses.
Use Microsoft's Office License Removal Tool
Removing the hidden Office 2019 license files forces your Mac to prompt for new activation credentials, allowing Microsoft 365 to activate properly.
macOS stores Microsoft Office license files in a secure system directory. When you upgrade to Microsoft 365, the system may still prioritize your old Office 2019 license file, causing the older version to load. Clearing this license cache resolves the conflict.
Log in to the Services & subscriptions page on the Microsoft account portal to confirm your Microsoft 365 subscription is active and valid.
Download the official Microsoft Office License Removal Tool for Mac directly from the Microsoft support website.
Open the downloaded .pkg file, follow the installation prompts, and execute the tool to completely remove the hidden Office 2019 license from your Mac.
Reinstall Microsoft 365 from your Microsoft account portal. Once installed, launch Word and sign in with your current Microsoft 365 credentials to activate the software.

Frequently Asked Questions
Will running the Office License Removal Tool delete my Word documents?
No. The Office License Removal Tool only deletes the hidden activation files associated with the software itself. Your personal Word documents, Excel spreadsheets, and presentations are completely safe and will remain unaffected.
Why doesn't Microsoft 365 automatically overwrite Office 2019 on a Mac?
macOS separates application files from license files. Even if you install the newer Microsoft 365 applications, the system continues to detect the old Office 2019 license file stored in the Library folder. Because the older license is still valid for those specific versions, the software defaults to it.
Do I need to uninstall Office 2019 before installing Microsoft 365?
While simply deleting the older applications by moving them to the Trash is good for saving space, it will not remove the license files. You must use the License Removal Tool to prevent version conflicts and unlock Microsoft 365 features.
