Retention period for Dismissed alerts in IRM case management in Purview

As per Microsoft, the Dismissed alert stays for 120 days. 

Hi,

Thanks for the reply, but in my tenant i can see the Dismissed IRM alerts still after 30 days. Do you know where to check in the settings section?

Hi Avisheck,

Dismissed alerts in the IRM alert section of Purview typically stay in the dashboard for 30 days before they are automatically removed. However, this retention period may vary depending on the specific configuration or settings in your environment.

Regards!
