Office 365 Activation Troubleshooting Guide

Issue:

If you're unable to activate Office 365 after signing in with your Lehigh University username and password on a Mac, follow these troubleshooting steps before using the License Removal Tool.

Common Cause:

Activation issues on Mac can be caused by outdated software, temporary glitches, or conflicting license data tied to your account.

Troubleshooting Steps:

1. Ensure You're Signed in Correctly

   • Make sure you're signing into Office 365 using your Lehigh University credentials (username@lehigh.edu and associated password).

2. Restart Your Mac

   • Restarting your Mac can often resolve activation issues by refreshing system processes and clearing any temporary problems.

3. Check for Office Updates

   • Open any Office 365 app (such as Word or Excel), click on the Help menu, and select Check for Updates.

   • Make sure Office is updated to the latest version, as updates often fix activation issues.

4. Uninstall and Reinstall Office
   If updating doesn’t resolve the issue:

   • Open Finder > Applications, find the Microsoft Office apps, and drag them to the Trash.

   • After uninstalling, reinstall Office 365 from the Lehigh University Office 365 portal.
