The products developed by Microsoft are in use by millions around the world. For example, it is recorded that Office 365 gets more than 60 million monthly active users. This shows how vital such tools have become, both in personal and business transactions.
But what if, all of a sudden, you get shut out? Thousands of users have been facing the issue of Error Code 135011, which prevents them from signing in to their MS Office applications.
If this is the problem you are facing, then you have nothing to be concerned about. There are some troubleshooting ways to try. The error generally includes the blocking of the device from accessing Office 365 due to its earlier remote activation using an account that has become invalid.
Also, there may be the occurrence of problems at the servers. Following are some actions you can take in order to troubleshoot and then fix Error Code 135011.
Fix #1: Change Connection Network
Sometimes the root cause of the issue could be the network you’re on. Some networks, and this will often be public or restricted networks, block the authentication required to verify your credentials.
It results in the appearance of Error Code 135011. For troubleshooting, try switching over to another network:
- Public Wi-Fi-If you are on any public Wi-Fi, try it on a private or at least a stable network, such as a home or office network.
- If you are on a VPN, try turning it off. Check if the error persists.
Fix #2: Erase Credentials Related to MicrosoftOffice16_Data
Sometimes, the problem may also occur due to corrupted or expired credentials of your Microsoft account that might be cached on your system.
These specifically relate to a segment titled MicrosoftOffice16_Data. Here’s how you can remove credentials of this kind:
- Launch your Control Panel and click Credential Manager.
- Click Windows Credentials.
- Find any entries titled MicrosoftOffice16_Data.
- Highlight and remove these entries.
Once these credentials are cleared, reboot your computer and log in again to see if the issue is fixed.
Fix #3: Check with Your Admin
If you are using a work or school account, it’s possible that Error Code 135011 is tied to administrative restrictions.
In this case, your account might be blocked by your organization’s administrator due to security policies or account management rules.
So contact your system or IT administrator and explain the issue. Once your admin clears things up, try logging in again to see if the error persists.
Fix #4: Check if it’s a Server Issue
Sometimes, Error 135011 has to deal with the Microsoft servers and not your connection or credentials. This could well be because of maintenance, server downtimes, or something wrong from Microsoft’s end.
To check if this is so: head over to the Microsoft Service Status page to see if there are reports about service outrages or authentication issues.
Fix #5: Run a Full Security System Scan
Sometimes, malware can interfere with your device’s ability to authenticate properly. Running a full system scan can help detect and remove malicious software that might be triggering the Error Code 135011. Use a reliable security program to do this:
- Run a full scan using a trusted antivirus or antimalware tool.
- If you don’t have one, try Outbyte AVarmor, which can detect and remove threats that might affect your authentication process.
After completing the scan, reboot your computer and check if the error still occurs.
