Frequently Asked Questions

Why do Microsoft Office apps close immediately after showing an error?

This commonly happens due to corrupted application files, conflicts with third-party COM add-ins, or system inconsistencies following a recent Windows OS update. When the application cannot load necessary background components, it forces a shutdown to prevent further errors.

Will running an Office Repair delete my documents or emails?

No. Running a Quick Repair or an Online Repair from the Windows Control Panel only replaces or fixes the core program files and registry entries required for Microsoft 365 to function. It will never touch or delete your personal Word documents, Excel workbooks, or Outlook data.

How do I safely back up my Outlook data before reinstalling?

To back up Outlook, open the application and navigate to File > Open & Export > Import/Export. Choose 'Export to a file', select 'Outlook Data File (.pst)', check the top-level folder to include all subfolders, and save the exported PST file to a safe location such as an external drive or cloud storage.
