Frequently Asked Questions
Why is Microsoft 365 telling me I don't have permission to save or create files?
This typically occurs due to account synchronization issues, corrupted Office installation files, conflicting third-party add-ins, or incorrect Windows registry permissions that block the application's write access.
Does repairing Microsoft 365 delete my existing documents?
No, running a Quick Repair or Online Repair only fixes the application files and registry keys. Your personal documents, spreadsheets, and presentations remain completely untouched.
How do I know if an add-in is causing the file creation error?
You can test this by launching Word, Excel, or PowerPoint in Safe Mode by holding the Ctrl key while clicking the application icon. If you can successfully create files in Safe Mode, a third-party add-in is likely the culprit and should be disabled.
Can I use another program to open my Microsoft 365 files if the application is broken?
Yes, you can use alternative office suites like WPS Office to open, edit, and create .docx, .xlsx, and .pptx files seamlessly while you troubleshoot your Microsoft 365 installation.
