Fix Office 365 Mac Login Problems After Switching Accounts

Product: Microsoft Office 365
Device & OS: Mac
Scenario: Switching the primary Office license from a personal Microsoft account to a school or organization Microsoft 365 account.
Observed behavior: Office applications continue to prompt for or use the deleted personal account's login credentials, and simply reinstalling the individual applications does not clear the old account data.

Before you start

Before proceeding with a complete uninstallation, ensure you have your new school or work Microsoft 365 login credentials handy and back up any unsaved documents or local Outlook data.

Solution 1Recommended

Use the Microsoft Office Removal Tool and Reinstall

Use Microsoft's official tools to completely remove hidden license files and cached account data before reinstalling the software from your organization's approved source.

Dragging Office apps to the Mac Trash does not remove the hidden library files where your old personal account license is stored. A complete removal is required to force Office to prompt for your new work or school credentials.

Run the License Removal Tool

Download and run the official Microsoft Office License Removal Tool for Mac. Follow the on-screen prompts to clear all existing account credentials and licenses from your Mac's keychain.

Completely remove Office data (if necessary)

If running the tool is not enough, open Finder, navigate to the Applications folder, and move all Microsoft Office apps (Word, Excel, PowerPoint, Outlook) to the Trash. Then, navigate to the hidden '~/Library/Containers' and '~/Library/Group Containers' folders and delete all folders starting with 'com.microsoft'.

Reinstall Microsoft 365

Log in to your school or organization's Microsoft 365 portal in your web browser. Download the approved Office installer package and complete the installation process to ensure you have the latest version.

Sign in with the new account

Launch Microsoft Word or Excel. When prompted, sign in using your active school or work account to properly activate the license.

Re-add Outlook email accounts

Because complete removal resets all configurations, open Microsoft Outlook and follow the setup wizard to add your email accounts again.

Use the Microsoft Office Removal Tool and Reinstall

Complete Uninstallation: A complete uninstallation ensures that hidden cache files storing your old personal account details are permanently deleted, paving the way for a clean sign-in experience.

Frequently Asked Questions

Why does my Mac still remember my old Microsoft account after uninstalling Word?

Dragging a single Office application to the Trash does not remove the hidden Library cache files or Mac Keychain entries where Microsoft stores your account license and login credentials. You must use the removal tool or delete the specific group container folders to clear this data.

Do I need to reconfigure Outlook after completely reinstalling Office on Mac?

Yes. A complete removal will clear your Outlook profiles and settings to fix the account conflicts. You will need to launch Outlook and add your school, work, or personal email accounts again.

Can I use both a personal and work account on Office for Mac?

Yes, you can add connected services for multiple accounts, but the primary software license must be activated with one valid account. Conflicts typically occur if the primary licensed account is deleted, expired, or switched improperly without clearing the old cache.
