What happens if you uninstall Microsoft 365?
Microsoft explicitly says uninstalling Microsoft 365 removes the applications from the computer but does not delete the documents, files or workbooks you created.
3 primary verified consequence reports plus 3 indexable preparation guides. This hub prioritizes source-backed pages with distinct search intent and keeps scenario briefs out of the main crawl path.
Uninstalling software, signing out and ending a paid license are different actions. This hub separates device installation state from account entitlement so removing an app from one PC does not get confused with cancelling the service itself.
Before changing license state, identify locally stored files, cloud-synced content, activated devices and the account that owns the subscription. Verify which features remain available in free web apps and which depend on the paid plan.

You can still use Microsoft’s free web apps with a Microsoft account, but paid desktop features, storage and premium benefits depend on the subscription you leave.
