Microsoft 365 Developer E5 license lacking endpoints and device ON defender portal
Dear Support Team, I am a microsoft certified trainer (MCT). I currently have a Microsoft 365 Developer E5 license assigned to my tenant. However, I have noticed that my Microsoft Defender portal (security.microsoft.com) is missing several critical features. For example, I cannot see the Endpoints or Devices menus, which is preventing me from implementing and testing Microsoft Defender for Endpoint. Additionally, my Azure tenant and Microsoft 365 tenant are separate. This has created challenges when configuring security services such as Microsoft Sentinel (SIEM), as certain prerequisites and integrations require configuration through the Microsoft Defender portal. Due to the missing Defender features, I am unable to complete the necessary setup. I would appreciate your assistance in understanding: Why the Endpoints and Devices sections are unavailable in my Defender portal despite having a Microsoft 365 Developer E5 license. Whether additional licensing, onboarding steps, or tenant configurations are required to enable Microsoft Defender for Endpoint features. How best to integrate or align my separate Azure and Microsoft 365 tenants to support services such as Microsoft Sentinel and Defender XDR. These issues are significantly impacting my ability to evaluate and implement Microsoft's security solutions. I would appreciate any guidance or recommendations to resolve them.
Security Admin Center Tenant Allow/Block List Not Able to Block IPv4?
While using the Security Admin Center Tenant Allow/Block List we have been able to block specific email addresses and IPv6 IP addresses but are unable to block IPv4 IP addresses. We have tried both using the console and the CLI but have turned up unsuccessful both times when it comes to IPv4. A large majority of the phishing attempts that we encounter come from IPv4 addresses but we have been unable to block any of these. Will there ever be functionality for IPv4 within the Tenant Allow/Block list or is the only option to use conditional access policies? Also why is this enterprise tool only functional with IPv6 and without documentation stating that it does not work for IPv4?I built a free, open-source M365 security assessment tool - looking for feedback
I work as an IT consultant, and a good chunk of my time is spent assessing Microsoft 365 environments for small and mid-sized businesses. Every engagement started the same way: connect to five different PowerShell modules, run dozens of commands across Entra ID, Exchange Online, Defender, SharePoint, and Teams, manually compare each setting against CIS benchmarks, then spend hours assembling everything into a report the client could actually read. The tools that automate this either cost thousands per year, require standing up Azure infrastructure just to run, or only cover one service area. I wanted something simpler: one command that connects, assesses, and produces a client-ready deliverable. So I built it. What M365 Assess does https://github.com/Daren9m/M365-Assess is a PowerShell-based security assessment tool that runs against a Microsoft 365 tenant and produces a comprehensive set of reports. Here is what you get from a single run: 57 automated security checks aligned to the CIS Microsoft 365 Foundations Benchmark v6.0.1, covering Entra ID, Exchange Online, Defender for Office 365, SharePoint Online, and Teams 12 compliance frameworks mapped simultaneously -- every finding is cross-referenced against NIST 800-53, NIST CSF 2.0, ISO 27001:2022, SOC 2, HIPAA, PCI DSS v4.0.1, CMMC 2.0, CISA SCuBA, and DISA STIG (plus CIS profiles for E3 L1/L2 and E5 L1/L2) 20+ CSV exports covering users, mailboxes, MFA status, admin roles, conditional access policies, mail flow rules, device compliance, and more A self-contained HTML report with an executive summary, severity badges, sortable tables, and a compliance overview dashboard -- no external dependencies, fully base64-encoded, just open it in any browser or email it directly The entire assessment is read-only. It never modifies tenant settings. Only Get-* cmdlets are used. A few things I'm proud of Real-time progress in the console. As the assessment runs, you see each check complete with live status indicators and timing. No staring at a blank terminal wondering if it hung. The HTML report is a single file. Logos, backgrounds, fonts -- everything is embedded. You can email the report as an attachment and it renders perfectly. It supports dark mode (auto-detects system preference), and all tables are sortable by clicking column headers. Compliance framework mapping. This was the feature that took the most work. The compliance overview shows coverage percentages across all 12 frameworks, with drill-down to individual controls. Each finding links back to its CIS control ID and maps to every applicable framework control. Pass/Fail detail tables. Each security check shows the CIS control reference, what was checked, what the expected value is, what the actual value is, and a clear Pass/Fail/Warning status. Findings include remediation descriptions to help prioritize fixes. Quick start If you want to try it out, it takes about 5 minutes to get running: # Install prerequisites (if you don't have them already) Install-Module Microsoft.Graph, ExchangeOnlineManagement -Scope CurrentUser Clone and run git clone https://github.com/Daren9m/M365-Assess.git cd M365-Assess .\Invoke-M365Assessment.ps1 The interactive wizard walks you through selecting assessment sections, entering your tenant ID, and choosing an authentication method (interactive browser login, certificate-based, or pre-existing connections). Results land in a timestamped folder with all CSVs and the HTML report. Requires PowerShell 7.x and runs on Windows (macOS and Linux are experimental -- I would love help testing those platforms). Cloud support M365 Assess works with: Commercial (global) tenants GCC, GCC High, and DoD environments If you work in government cloud, the tool handles the different endpoint URIs automatically. What is next This is actively maintained and I have a roadmap of improvements: More automated checks -- 140 CIS v6.0.1 controls are tracked in the registry, with 57 automated today. Expanding coverage is the top priority. Remediation commands -- PowerShell snippets and portal steps for each finding, so you can fix issues directly from the report. XLSX compliance matrix -- A spreadsheet export for audit teams who need to work in Excel. Standalone report regeneration -- Re-run the report from existing CSV data without re-assessing the tenant. I would love your feedback I have been building this for my own consulting work, but I think it could be useful to the broader community. If you try it, I would genuinely appreciate hearing: What checks should I prioritize next? Which security controls matter most in your environment? What compliance frameworks are most requested by your clients or auditors? How does the report land with non-technical stakeholders? Is the executive summary useful, or does it need work? macOS/Linux users -- does it run? What breaks? I have tested it on macOS, but not extensively. Bug reports, feature requests, and contributions are all welcome on GitHub.

Happy to answer any questions in the comments.Disable incessant nagware popups
I don't know about everyone else, but I am sick and tired of the nagware pop ups in Word, Excel, PowerPoint, Outlook, etc. Every single product harasses me with pop ups trying to tell me "hey, did you know this feature was here?", "you can do this if you click that", "let me hold your hand through using products you've used for decades even though you don't want daddy Microslop to do that". This is a prime example. I keep getting the same ones again and again and again and everything I've read indicates they should only appear once. But they don't. They keep coming back like a psychotic stalker ex who wants alimony even though you were never married. How do I get this nagware to stop?!
Ugly Defender awareness training screen
I want to use the extensive training material available from the E5 licenses we just shelled out a boat load of $$ for. However, when someone gets an invite and they click the link to do the training they are taken to the Defender page. This might be fine for a technical person but its ugly as F for my users. Plus, there is extra rubbish like Threat Intelligence, Trials, Reports, settings etc they can access that I don't want them too. This is not a very polished interface for non-technical people. Is there a way to fix this? Can it send them the direct training URL, so it just opens the training and not the defender page from them to open the video? Can we do a custom landing page but put the assigned training URLs into that? This is ugly there has to be a way to make this more user friendly.How to Check if Shared Mailboxes Need MDO Licenses
Shared mailboxes might need Microsoft Defender for Office 365 licenses, but how do you identify how many licenses? We use PowerShell to do the job by analyzing external email sent to shared mailboxes. If a mailbox receives external email, then by definition the mailbox receives benefit from MDO, and that’s the test for requiring a license. https://office365itpros.com/2025/11/25/microsoft-defender-for-office-365-3/
Microsoft Issues Updated Guidance for Defender for Office 365 Licensing
Some inconsistencies in the MDO P2 service description and licensing terms exposed a need for tenants to license every user and shared mailboxes. Microsoft has changed the service description and licensing terms to make them simpler. Mailboxes still need MDO licenses, but only if they benefit from MDO protection, including MDO P2 if that’s what they use. Tenant admins have some extra work to do to deploy policies. All explained here. https://office365itpros.com/2025/10/31/mdo-p2-licensing/
