Issue: How to fix Microsoft Office error 0xC0070057 in Windows?
Hello. I have recently reset my Windows and had to reinstall all programs. However, I can no longer log in to Microsoft Office because of the error 0xC0070057. Please advise on what to do here because I'm baffled.
Microsoft Office is a powerful suite of productivity applications developed by Microsoft Corporation, designed to assist individuals and businesses with a wide range of tasks. The software suite includes popular applications such as Word, Excel, PowerPoint, Outlook, and OneNote, which enable users to create documents, presentations, manage emails, and organize information. Microsoft Office has become an indispensable tool for modern computing due to its versatility and user-friendly interface.
However, some users have encountered an issue when logging in to Microsoft Office applications, specifically the error code 0xC0070057. This error prevents them from accessing their Office applications and can be particularly frustrating for those relying on Microsoft Office for daily tasks.
The 0xC0070057 error may occur for various reasons, some of which include corrupt login credentials, signing into multiple Microsoft accounts simultaneously, internet connectivity issues, or using an outdated Office app.
Corrupt login credentials can prevent users from signing in to their Microsoft Office applications, resulting in the 0xC0070057 error. In cases where a user has multiple Microsoft accounts or is logged into more than one account at a time, the error might be triggered due to conflicts between the accounts. To resolve this, users may need to sign out of all Microsoft accounts, clear cache and cookies, and then attempt to sign in again.
Internet connectivity issues can also lead to the 0xC0070057 error when signing in to Office applications. Users should ensure they are connected to a stable internet connection before attempting to sign in again. Lastly, an outdated version of the Office app can cause sign-in errors due to compatibility issues. To address this problem, users should ensure they have the latest version of the Office app installed.
It is important to note that the 0xC0070057 error is not exclusive to a specific version of Microsoft Office or Windows. It can potentially affect any user, regardless of whether they are using a standalone desktop version of Office or the Office 365 subscription service.

Don’t pay ransomware authors – use alternative data recovery options
Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files – Data Recovery Pro.
