Question details
Users are encountering error code 80070005 when attempting to sign in or activate Office 365, preventing access to the applications.
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Signing in or activating Microsoft Office 365 on a Windows computer.
- Observed behavior
- The sign-in process fails with error code 80070005 due to a registry conflict or corrupted Windows user profile, which standard Office repairs cannot fix.
Ensure you have administrator privileges on your Windows computer, as you will need them to create a new user account and manage system settings.
Create a New Windows User Profile
Creating a new Windows profile isolates the issue and bypasses the corrupted registry settings causing the activation failure.
Since error 80070005 is typically tied to an 'Access Denied' registry conflict within a specific user profile, standard Office and Windows updates will not resolve it. Moving to a fresh profile is the most reliable workaround.
Click the Start menu and open 'Settings'. Navigate to 'Accounts' and select 'Family & other users' (or 'Other users' depending on your Windows version).
Click 'Add someone else to this PC'. Follow the prompts to create a new local account, and make sure to change the account type to 'Administrator'.
Sign out of your current Windows profile and log in with the newly created account. Open any Office 365 application and attempt to sign in and activate.
If Office activates successfully, use File Explorer to copy your documents, pictures, and desktop files from C:\Users\[OldUsername] to your new user profile folder.
Seek Advanced Windows Support
If you are unable to migrate to a new profile, you will need to seek IT assistance to repair the specific registry conflict.

Frequently Asked Questions
Why does error code 80070005 happen only on one Windows account?
This error translates to 'Access Denied'. It means the specific registry keys required for Office activation in your current user profile lack the proper permissions or have become corrupted, while other profiles on the same computer remain unaffected.
Will reinstalling Microsoft Office fix error 80070005?
Generally, no. Standard Office reinstallations or online repairs do not resolve this error because the root cause lies within the Windows user profile's registry settings, not the Office installation files.
How do I safely transfer files to my new Windows profile?
Open File Explorer and navigate to the C:\Users directory. Open your old username's folder and copy the contents of your Desktop, Documents, Downloads, and Pictures folders. Paste them into the corresponding folders in your new user profile directory.
