Frequently Asked Questions

Why is my Microsoft 365 subscription only opening web apps?

This typically occurs if you have not downloaded the desktop applications, or if your specific subscription tier (such as Microsoft 365 Basic) only includes access to the online web versions of Office.

Will repairing Microsoft 365 delete my personal files?

No, running a Quick Repair or Online Repair from Windows Settings only resets and replaces the application files. Your personal documents, spreadsheets, and presentations will remain safe and unaffected.

How do I know if my Microsoft account is linked to an active subscription?

You can verify this by logging into the Microsoft account services page online. Any active subscriptions linked to your email address will be clearly listed under the 'Services & subscriptions' section.
