Hello, @Brynel Peter Libera (CONVERGYS CORPORATION) !
How do I remove recommendation for deleted resource?
This is likely due to either a delay or unexpected behavior within Azure. The most straight forward solution is to exempt the deleted resource from recommendations:
https://learn.microsoft.com/en-us/azure/defender-for-cloud/exempt-resource
In the Defender for Cloud portal, open the Recommendations page, and select the recommendation you want to exempt.
Additionally, you can attempt to retrigger the scan (disable and enable) or wait a day or two for the recommendation to update on its own. It's also a good idea to create a support ticket to track the issue and unblock the issue if it has not resolved already.
I hope this has been helpful! Your feedback is important so please take a moment to accept answers.
