Other potential causes include incomplete or failed Office repairs, network connectivity issues, outdated system files, or multiple conflicting Office installations on the same system. Now that you know the causes, let’s discuss the solutions.
1. Change Internet Connection
Sometimes, this error can occur due to problems with your internet connection. A weak or unstable network may interrupt the activation process, leading to errors like the 7q6ch tag. Switching to a different connection—such as a mobile hotspot or another Wi-Fi network—can help resolve the issue, as each connection may use different DNS settings or routing paths.
2. Run SFC and DISM
This error can sometimes be triggered by corrupted or missing system files. Running built-in tools like System File Checker (SFC) and Deployment Image Servicing and Management (DISM) can help resolve these issues. SFC scans your system for corrupted or missing files and automatically repairs them, while DISM fixes problems with the Windows system image that might be affecting core components, including those used during Office activation.
3. Add Account Manually
This issue can sometimes occur due to improper synchronization between Microsoft Office applications and your Microsoft account. Manually adding your account helps re-establish the connection, ensuring that all Office services are properly linked and synchronized.
4. Open Outlook in Safe Mode
If the error only appears when using Outlook, try launching it in Safe Mode. Safe Mode disables unnecessary add-ins, resets custom settings, and runs Outlook with its default configuration. This can help resolve the error if it’s caused by a misbehaving add-in or user-specific setting. It also helps confirm whether the issue is related to Outlook’s settings or extensions. To troubleshoot further:
5. Rename OneAuth and IdentityCache Folders
Renaming the OneAuth and IdentityCache folders can help resolve this error, as these folders store cached authentication data used for temporarily saving login credentials. Sometimes, this cached data can become corrupted, leading to sign-in or activation errors. By renaming these folders, the system is forced to recreate fresh authentication files, which may eliminate the issue. For each folder:
After renaming both folders, close all Microsoft applications. Restart your computer. The system will automatically recreate fresh versions of these folders.
