The “Something Went Wrong [1001]” error in Microsoft 365 can be frustrating when you’re trying to access your work or personal documents. This error typically occurs due to authentication issues, corrupted user profiles, or conflicts with security software. Let’s explore some effective methods to resolve this problem and get you back to work.
Clear Browser Cache and Cookies
Clearing your browser’s cache and cookies is often the quickest fix for many Microsoft 365 login issues.

Step 3: Select the option to clear browsing data.
Step 4: Ensure “Cookies” and “Cached images and files” are checked.
Step 5: Click “Clear data” and restart your browser.
After clearing your cache, try logging into Microsoft 365 again. If the error persists, move on to the next method.
Repair Microsoft 365 Installation
A corrupted Office installation can cause authentication errors. Using the built-in repair tool can often resolve these issues.

Disable Security Software Temporarily
Sometimes, overzealous antivirus or firewall software can interfere with Microsoft 365’s authentication process.
Step 1: Temporarily disable your antivirus software.
Step 2: Turn off Windows Defender by going to Windows Security > Virus & threat protection > Manage settings.

Remember to re-enable your security software after testing, as leaving it off can expose your system to risks.
Recreate the Microsoft 365 Profile
If the error persists, your user profile might be corrupted. Creating a new profile can often resolve persistent authentication issues.
Step 1: Close all Microsoft 365 applications.
Step 2: Press Windows + R to open the Run dialog.
Step 3: Type %localappdata%\Microsoft\Office\16.0 and press Enter.
Step 4: Rename the Outlook folder to Outlook.old.
Step 5: Restart Outlook and set up your account again.
This process creates a new profile while preserving your old data in case you need to recover anything.
Update Windows and Microsoft 365
Outdated software can lead to compatibility issues and errors. Keeping your system and applications up-to-date is crucial for smooth operation.
Step 1: Open Windows Settings and go to “Update & Security.”
Step 2: Click “Check for updates” and install any available updates.
Step 3: Open any Microsoft 365 application and go to File > Account > Update Options > Update Now.
Step 4: Restart your computer after all updates are installed.
Regular updates not only fix bugs but also improve security and add new features to your software.
