Remove ads and improve Outlook's web mailbox.

Features & Capabilities

Outlook Web Plus is a Chrome extension designed to improve your Outlook web mailbox by removing intrusive advertisements for a cleaner and more efficient browsing experience. It works by dynamically modifying the Document Object Model (DOM) of Outlook's web interface to silently eliminate unwanted ad elements without affecting essential content.

Beyond ad removal, Outlook Web Plus introduces additional features aimed at enhancing everyday email management in Outlook's web client. This extension ensures a smoother, distraction-free inbox, helping you focus directly on your emails. The source code is openly available on GitHub, promoting transparency and security.

Is Outlook Web Plus Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Outlook Web Plus requires a few sensitive permissions. Exercise caution before installing.
