If you are encountering the error code 0xc0070057 while trying to launch any Office 365 application, please follow the steps below to troubleshoot the problem:
1. Verify Your Internet Connection
The error 0xc0070057 might sometimes arise due to issues with Office apps reaching Microsoft servers. Since Office 365 requires a robust internet connection to access your files, start by ensuring your network is stable.
If you identify slow or unstable connectivity, try restarting your router or modem. If the problem continues, you can flush your DNS by using the Command Prompt. To do this, open Command Prompt as an administrator and input the following command:

If you were utilizing a trial version of Office 365, the error may display once the trial period expires. If you have already purchased Office 365, try logging out of your existing account. Restart your PC, and once it boots up, sign back into Microsoft Office.
To log out of Office 365, follow these steps:
- Open an Office application.
- Navigate to File > Account and sign out of your current account.
- Close all Office applications and reboot your device.
- Once your system restarts, go to Settings > Accounts > Email & Accounts.
- Select the “Add a Work or School Account” option.
- Now, log in with a valid Microsoft account and its corresponding password.
If the error was related to a trial expiration, this should solve the 0xc0070057 issue.
