Frequently Asked Questions
Will repairing Office delete my files?
No. Repairing Office only affects the application files, not your documents. Your Word documents, Excel spreadsheets, and other files are safe. However, custom add-ins or templates may need to be reconfigured.
How long does an Online Repair take?
Online Repair typically takes 30-60 minutes depending on your internet speed, as it re-downloads the full Office installation. Quick Repair usually completes in 5-15 minutes.
