Frequently Asked Questions
Why do Microsoft Office apps stop working after a Windows update?
System updates can sometimes overwrite shared dynamic link libraries (DLLs), change background registry settings, or cause temporary compatibility conflicts that break the communication between the OS and the Office applications.
Will running the Office Repair tool delete my documents or Outlook emails?
No. Both Quick Repair and Online Repair only target the software's application files. Your personal Word documents, Excel spreadsheets, and locally cached Outlook emails will remain intact.
How can I verify which Microsoft account is linked to my Office subscription?
You can check your linked products by navigating to account.microsoft.com/services in your web browser and logging in with your Microsoft email address. Your active Office subscriptions will be listed there.
