Office Home & Business 2019 license no longer recognized after reinstall ("No license found")
Hello everyone, I'm looking for some help because Microsoft Support has not been able to solve this issue. I own a genuine perpetual license of Office Home & Business 2019 for Mac, linked to my Microsoft account since August 2019. The license is still listed under Services & Subscriptions, but Office no longer activates. My hardware MacBook Pro (Retina, 13-inch, Late 2012) Model: MacBookPro10,2 Intel Core i5 8 GB RAM macOS Ventura 13.7.8 Installed using OpenCore Legacy Patcher Office version originally working: 16.78 Later tested with 16.101 and 16.93 Same result on every version What happened Office had already been successfully activated and worked normally. I was able to: create documents edit documents save documents After restarting the Mac, Office suddenly requested activation again. Since then it has never activated successfully. Initially Office failed to activate with an unknown error. After completely uninstalling and reinstalling Office using Microsoft's installer, the activation process changed. I can now successfully sign in with my Microsoft account, but after authentication Office displays: "No license found for this account." My Office Home & Business 2019 license is still present in my Microsoft account under Services & Subscriptions. Even though my Microsoft account clearly owns Office Home & Business 2019 for Mac. Microsoft account The license appears correctly under: Services & Subscriptions Office Home & Business 2019 for Mac Added to my account on August 7, 2019. The website instructs me to open an Office application and sign in to activate. Everything I've already tried Uninstalled Office completely Installed Office again using Microsoft's installer Installed Office 16.78 Installed Office 16.93 Updated to Office 16.101 Removed Office containers Removed Group Containers Deleted OneAuth cache Deleted Entrabroker cache Removed activation tokens Cleared Office preferences Signed out and signed back into Microsoft account Deleted Office credentials from Keychain Reinstalled Microsoft AutoUpdate Verified no MDM profile exists Verified Internet Accounts Verified Microsoft account Microsoft Support remotely accessed my Mac and repeated all troubleshooting steps Nothing solved the issue. Additional information Running: defaults read com.microsoft.office returns: OfficeActivationLicense = NoLicense although: OfficeActivationEmailAddress = email address removed for privacy reasons is correctly detected. The activation window successfully reaches Microsoft's login page. Office now asks for my Microsoft account credentials. Authentication completes successfully. After a few seconds Office reports: "No license found for this account." It then offers only two options: Buy Microsoft 365 Use another account Microsoft Support remotely connected to my Mac, completely removed Office, installed a newer official installer, and the problem remained exactly the same. My question Has anyone experienced this after reinstalling Office 2019? Could this be: a licensing server issue? an incompatibility introduced after Office 2019 reached end of support? an activation problem related to OpenCore Legacy Patcher? something else? I would really appreciate any suggestions. Thank you very much. Additional notes: The Office license has been associated with the same Microsoft account since 2019. The same installation was successfully activated and worked normally before the problem started. The issue only appeared after restarting the Mac. Microsoft Support has already remotely accessed my computer and could not resolve the problem.
