Short answer
Outlook Power Tools is a free Outlook ad blocker for Chrome. It hides Outlook Web ad surfaces while keeping email templates, Quick Steps, PDF export, shortcuts, unread badge, and attachment reminder in the same extension.
Outlook Power Tools ad blocking runs in the browser on outlook.live.com, outlook.office.com, and outlook.office365.com. The extension does not sell ad inventory or replace Outlook ads with its own ads.
What it removes
| Ad surface | How it appears in Outlook Web |
|---|---|
| Sidebar ads | Display ads beside the message list or reading pane. |
| Sponsored message rows | Ad rows that can look similar to email messages. |
| Upgrade banners | Prompts to upgrade Outlook or Microsoft 365. |
| Ad labels | Small "Ad Choices" or sponsored labels around ad slots. |
Why use a dedicated Outlook ad blocker?
Generic ad blockers can miss Outlook-specific interface elements or hide too much. Outlook Power Tools targets Outlook Web surfaces and pairs ad removal with inbox productivity tools built for New Outlook users.
