Marking Quarantine Notice senders as safe for entire tenant
Our users get quarantine notices weekly. They're configured to come from mailto:email address removed for privacy reasons (the domain specific to tenant).. sometimes they come from mailto:email address removed for privacy reasons anyways, but this is fine. The thing is, I end up with a LOT of users who end up receiving these in their junk mail. We have a lot of tenants - I don't really have the time to keep checking them, taking action on mis-junked items. Most stuff is configured to go to quarantine anyway. What's the best way to allow these senders? The IB Anti-Spam safe-senders component is not Secure-Score recommended, and we try to keep these scores high. But the tenant allow/block list allows a max of 45days since last use. There's so many options, I'm a little confused as to what's 'right' Thanksuser-reported phishing emails
Dear Community I have a technical question regarding user-reported emails. In Defender, under “Action and Submissions” -> “Submissions,” I can see the emails that users have reported under the “user reported” option. There, we have the option to analyze these emails and mark them as “no threats found,” “phishing,” or “spam.” The user is then informed. Question: Do these reported emails remain in the user's inbox when they report them? If not, do we have the option to return these reported emails to the user's inbox with the “No threats found” action? Because I don't see this option. In another tenant, under “Choose response Action,” I see “move or delete,” but the “inbox” option is grayed out. Why is that? Thank you very much!'system has learned from the submission / mail is automatically allowed'
Hey folks, got an alert about a tenant allow//block list entry expiring. Only recently did we start getting these, because only recently did we start using expiring whitelisting. But I'm a little confused by the details, which says 'Mail from x is now automatically alllowed and the allow entry has been removed' and the activity that ''an allow entry is no longer required as the system has learned from the submission' The referenced email is actually an internal tenant - it receives ticket requests, and sends out ticket updates. But I'm REALLY curious about the 'automatic' allowing. Is this a feature limited to Defender 2, or part of Microsoft's AI detection framework for all 365 Defender/EOP? I don't even remember submitting this email - if I did, it was probably more than 45 days ago. So 1) Is this notice primarily that the entry had expired, but ALSO it's not needed or does this send out as soon as 'the system' recognizes it as legitimate, and removed regardless of the time left? 2) is there a way to review a list of entries Microsoft has 'accepted'? 3) What exactly does this 'allow'? I know that the tenant allow/block list allowed a certain set of lower-risk indicators in an email, but still blocked some higher-risk ones - unless there was a submission made. At that point, more is allowed. But there's still a limit, compared to a blanket bypass on the policy itself.Disabling Auto Align Feature in Microsoft Defender 365 Console Alerts
The Microsoft Defender 365 console has recently started auto aligning the alert screen upon clicking on an alert name, which seems to be part of the updated alert management experience. This change is quite bothersome and distracting. How can this feature be disabled?Microsoft Defender EOP
We have been experiencing an issue since last week where we are unable to view the details of quarantined emails. Could you please confirm if this is related to a known backend service issue, or if there are any specific troubleshooting steps we should perform on our end? Any guidance or updates would be greatly appreciated.
All Excel Macro Files Suddenly Flagged as Malware (X97M/Slacker.gen!A) Across M365 Starting April 16
Starting around 8 PM GMT+8 on April 16, 2025, macro-enabled Excel files with extensions such as .xlsm, .xlsb, or .xls began being automatically flagged as malware, specifically identified as X97M/Slacker.gen!A—when opened or edited in SharePoint, OneDrive, or Teams. Before this, the same files were not flagged as malicious, even when opened or edited, and this behavior had remained consistent for several months. This issue affects our entire tenant, with over 800 files being flagged as malware under the name X97M/Slacker.gen!A. These files are located across various locations and have been modified by different users. We are a Cloud-only tenant, and we have not done any configuration changes in Threat Policies for the past few months.
Defender bulk unsanction
I want to unsanctioned all Generative AI apps in cloud catalogue with a risk score 7 or below. But this is 970 apps and I don't feel like doing this one page of 20 at a time I'll be there all day. Can someone suggest a powershell script to set anything in that category risk score 0-7 as unsanctioned?Automated Investigation and Response
Upgraded to Defender for 365 P2 based on the idea of setting automated responses to certain alerts. That's how it was described. Now I'm trying to enable and configure it. The documentation has bounced me around 20 different articles for XDR, Defender Enterprise, Defender for Business... I do not see anywhere to configure the automation in Defender. One doc points me https://security.microsoft.com/securitysettings/endpoints/integration for making sure it's enabled. when I open this, and go down to Automation, it's simply an empty list of device groups. We don't use Device groups - we don't use Defender Endpoint. Has anyone configured this in a non-XDR environment? What I'm encountering and what was advertised seem very different...
