Frequently Asked Questions

Why didn't Quick Repair or Online Repair fix my Office applications?

Quick Repair only replaces missing or corrupted files based on a basic checklist. Online Repair is more thorough but can still fail if core Windows registry keys associated with Office are severely damaged or locked by conflicting background processes.

Will using the Office removal tool delete my personal documents?

No, the official Microsoft uninstall tool only targets Office application files, registry entries, and program data. Your personal Word documents, Excel spreadsheets, and Outlook data files (.pst) remain safe on your hard drive.

How do I create a new Outlook profile if it still refuses to open?

Close any error prompts, open the Windows Control Panel, and change the view to 'Large icons'. Click on 'Mail (Microsoft Outlook)', select 'Show Profiles', and click 'Add'. Name the new profile, enter your email credentials, and set the new profile as the default.
