How to Fix Microsoft 365 Basic Still Showing Ads in Outlook on the Web
Question details
The user is experiencing advertisements in Outlook on the web even though they have an active Microsoft 365 Basic subscription, which should provide an ad-free experience.

- Product
- Microsoft 365 Basic
- Device & OS
- not provided
- Scenario
- Accessing Outlook.com via a web browser after upgrading to a Microsoft 365 Basic subscription from a paid OneDrive plan.
- Observed behavior
- Advertisements continue to display in the Outlook.com web interface instead of the promised ad-free experience, despite clearing cache and using private browsing.
Ensure you have the exact Microsoft account credentials used to purchase the Microsoft 365 Basic subscription, as you will need them to verify your active plan status.
Verify Your Subscription and Refresh Your Outlook Session
Check that your Microsoft 365 Basic subscription is fully active and attempt to reset your browser session to force an account sync.
Sometimes, the web browser caches your previous free-tier account status. Verifying the subscription and forcing a fresh login can trigger the ad-free benefit.
Navigate to account.microsoft.com/services and log in with your Microsoft account to confirm that 'Microsoft 365 Basic' is listed as active.
Open Outlook.com, click on your profile picture in the top right corner, and select 'Sign out'.
Open a new InPrivate (Edge) or Incognito (Chrome) browser window to ensure no old cache is applied.
Go to Outlook.com in the private window and sign in using the email address associated with your Microsoft 365 Basic subscription to see if the ads are removed.

Contact Microsoft Support for Account Investigation
If local troubleshooting fails, the issue may be a backend provisioning error requiring Microsoft Support intervention.
Request a Subscription Cancellation and Refund
If Microsoft cannot resolve the ad-free benefit issue, you can request a cancellation and refund if eligible.

Frequently Asked Questions
Why am I seeing ads in Outlook if I have Microsoft 365 Basic?
This typically occurs due to a delay in backend account provisioning, a browser cache issue, or a glitch when transitioning from a legacy standalone OneDrive storage plan to the Microsoft 365 Basic tier.
Will uninstalling and reinstalling Office apps fix the ads in Outlook on the web?
No. Outlook on the web is a browser-based cloud service. Uninstalling local desktop or mobile applications will not remove advertisements from the web interface.
Does clearing my browser cache remove Outlook ads?
Clearing your browser cache or using an InPrivate window can help if the ads are caused by a stale session token. However, if the subscription hasn't properly synced on Microsoft's backend, the ads will persist even in a clean browser.
