Hi, There used to be Unified Audit Logs -option in Defender XDR Settings under "Endpoints". This option has now disappeared. Trying to search for Defender XDR events, such as isolating devices etc. using the Purview Audit search, I don't get any results. From the XDR Action center history I can see that isolation actions have been performed. I have Security Administrator permissions. Is there a way to enable/disable the XDR auditing from Defender XDR or Purview portals?127Views0likes2CommentsMS Defender Azure Arc Logic App
What is the best procedure for configuring a Logic App for Microsoft Defender in an Azure Arc environment? We had a very unexpected experience during onboarding—after configuring the Logic App, we missed setting a cap, and within a week, it consumed over $18K USD. I believe there must be a way to fine-tune the configuration to optimize costs. From my perspective, no organization would adopt an environment with such high costs for Microsoft Defender Plan 2 without better cost control measures in place. Could you suggest best practices or optimizations to prevent such excessive consumption?41Views0likes1CommentDefender MDO permissions broken (again)
Defender wasn't letting me approve pending AIR remediation options, something I do every day, with my usual custom RBAC role checked out. Nor could I move or delete emails. I also had Security Operator checked out. I checked out Security Admin and tried again, no dice. It wasn't until I checked out Global Admin until I got the permissions I needed.30Views0likes0CommentsInvestigation state Queued
I see a number of messages in our Defender XDR Incidents with a status of Queued. What does this status mean? This appears to only be related to Defender for Office 365 incidents, usually email reported as junk/phish/notjunk etc type of incidents. Regardless of whether I investigate or change the status of the incident, in remains in the Incidents list as queued. I cannot find clear documentation on what this state means or what action is required to resolve/close the incident. Can anyone shed any light on the what the queued state means and how to resolve a queued incident.1.5KViews0likes3CommentsMDO query of EmailEvents is not accepted in the flow which is why causing the badgateway error

Hi everyone, i was searching for an overview of where and AI is used in Defender XDR. Do you have a quick oversight of this? That would be great. Also how this data is used for training and decisions. I know it is used in Attack disruption and Copilot for Security ( ;) ) - but i need a complete list.

Here is a detailed post to the Microsoft help forum about tracking down who sent emails from a shared mailbox with delegated access and send as rights: Title: Tracking Sent Emails from a Shared Mailbox with Delegated Access Dear Microsoft Community, I'm reaching out for assistance with an issue I'm encountering regarding a shared mailbox in my organization. The shared mailbox has been configured with delegated access and "Send As" rights for certain users. However, I'm finding that emails are being sent from this shared mailbox, and I need to determine which user is responsible for those sent messages. Here's some more context on the setup: We have a shared mailbox that multiple employees within my organization can access and send emails from using their individual user accounts. The shared mailbox has been granted "Delegate Access" and "Send As" rights to these authorized users. Whenever an email is sent from the shared mailbox, it appears to come from the shared mailbox address rather than the individual user's email address. I need to be able to track down and identify which user sent a specific email from the shared mailbox. My main questions are: How can I determine which user account was used to send a specific email from the shared mailbox? Is there logging or audit functionality within Microsoft 365 that would allow me to see the user who sent an email from the shared mailbox? Are there any third-party tools or add-ons that could provide this level of tracking and visibility for emails sent from a shared mailbox? I'm hoping the Microsoft community can provide some guidance and recommendations on the best approach to resolve this issue. Being able to identify the user responsible for emails sent from the shared mailbox is crucial for maintaining security and accountability within our organization. Thank you in advance for your assistance. I look forward to hearing back from the community. Best regards,Solved344Views0likes1CommentPending actions notification via KQL / Graph API
Hello, I'm looking for a way to get notifications when an investigation is in Pending Approval state. I have tried searching the logs in Defender and Sentinel and have tried finding a graph request that could get this information, but no luck. Is this something that exists? Thank you for any help regarding this topic. Kristof68Views1like2CommentsXDR Unified RBAC deadline
Has Microsoft set a date for when the Unified RBAC permission model will become mandatory? All the documents I've read indicate that it's voluntary right now. Eventually it will become the default.
