Microsoft Sentinel: Incident Link Not Opening Referenced Incident — Troubleshooting Assistance Needed

Problem description

I am experiencing an issue where the links in incident notification emails from Microsoft Sentinel and Microsoft 365 Defender do not open the referenced incident as expected. Instead, clicking the link opens the incident list or only displays a limited number of incidents, and the specific incident does not open directly.

Environment

The affected service involves Microsoft Sentinel and Microsoft 365 Defender, specifically within the incident notification and portal-based incident experience.

What I've already tried

I have reviewed the incident notification email and attempted to click the links, but they only open the incident list rather than the specific incident. I also tried accessing the incident directly in the Sentinel portal by searching for the incident ID, but the link from the email does not navigate to it directly. Additionally, I have verified that the incident exists in the portal and is in an open state, with the incident ID matching the alert ID provided in the email.

Current status

I am seeking assistance to understand why the incident links in the notification emails are not opening the referenced incident directly and to find a solution to ensure the links work as intended.
