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.955Views2likes1CommentOffice 365 issues
We have an end user that started with us approximately a year ago. Shortly after he started he began noticing that his status would go away on a fairly regular basis on MS Teams. We tried uninstall/reinstall, resetting, repairing and the problem persisted. Since he was a relatively new hire we were thinking it was something with his laptop so we replaced and the issue returned. Turned in a ticket with our Office 365 vendor who in turn opened a ticket with Microsoft. After some initial testing they sent a Teams install file that seemed to fix the issue. Since that time he has regularly had issues with Teams disconnecting, Outlook just stop receiving emails, while showing connected. Typically the only fix was a restart and on some occasions that did not work. Sometimes a reset or repair might fix this issue. Throughout this we did clear credential manager, caches, etc...This got a point yesterday where I created a new user profile for him, basically like a new laptop and it temporarily fixed the Teams and Outlook issue, however when attempting to sign into MS Edge it would just spin and had to use task manager to close the app. Tried a repair on the app as you cannot uninstall and same result it would hang up and have to forcibly closed. Just wondering if someone else has encountered something like this and possible fixes. Thanks114Views0likes1CommentChatGPT Enterprise Apps Grab Some Work IQ
If installed into a Microsoft 365 tenant, ChatGPT Enterprise apps can access SharePoint Online files, Exchange Online email and calendar, and Teams chats, messages, and tasks. The Entra ID apps created by ChatGPT have the necessary permissions to access information accessible to the signed-in user. Microsoft 365 Copilot can access more information, but being able to process files, emails, calendar items, and chats and channel conversations delivers access to a lot of Work IQ. https://office365itpros.com/2026/03/24/chatgpt-enterprise-apps-workiq/41Views0likes0CommentsDisable 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?!101Views0likes1CommentDoes Microsoft have an employee directory?
Hi everyone, Quick question for the group. My company uses Microsoft Teams every day, and people are constantly trying to find the right person internally, who owns what, who reports to who, who sits in which team/department, etc. Teams search and profile cards help a bit, but we’re really looking for a proper employee directory, specifically: A clean employee directory experience (not scattered across different places). Rich employee profiles (photo, title, department, manager, contact info, location, etc.). Strong employee search (by name, department, role, location, ideally more) Is there a native employee directory in Microsoft 365 that does this well out of the box. If not, what are people using instead, SharePoint, Viva, custom build, or a third-party directory that pulls from Entra ID / M365? Would love to hear what’s working in real life.Solved254Views1like1CommentBlock users from creating Public Microsoft Teams groups
Hi Community, Is already know that Teams creation in Microsoft Teams is related to O365 groups, and if you would like to block users from creating teams, you need to block them from creating O365 groups, right? Ok, right. But what if we only want to block the possibility to create public teams, but still allow them to create private ones? Would that be possible? The answer is YES. And the solution is Microsoft Purview. You'll need to create a new Label/Label Policy under Information Protection. We'll configure the Label for the scope "Site, UnifiedGroup", with group settings as "Private" and applying the label automatically. Then we can configure/publish the Label Policy as mandatory for all the users, some of them or, as in my example, to a DL that contains all the users that I would like to block. Once published, depending on your tenant size, it can take up to 24 hours to propagate. In my test environment it was quite immediate. Now, the users added to the DL that I configured in the Label Policy can still create teams, but not Public ones ( and can't change the label ) as that option is greyed out. The answer is YES. And the solution is Microsoft Purview.18KViews0likes16CommentsTeams External Collaboration Administrator Role Arrives
Microsoft is introducing a new Entra ID role. The Teams External Collaboration administrator role allows users to manage external collaboration settings. Quite how often Microsoft 365 tenants need to manage these settings is unknown, but it’s a useful prompt to review the current set of roles used and users who are members of those roles. Time for an annual clean-up. https://office365itpros.com/2026/01/14/new-entra-id-role/244Views0likes0CommentsSharePoint vs Teams vs OneDrive: When to Use Each (and When Not To)
If your organization uses Microsoft 365? then you have gone through the pain point of which tool to use “Should this live in SharePoint, Teams, or OneDrive?” At first glance, all three tools seem to do the same thing store files, share documents, and help people collaborate. But using the wrong tool in the wrong situation can quickly lead to duplicated files, messy permissions, frustrated users, and lost productivity. This blog breaks down what SharePoint, Microsoft Teams, and OneDrive are actually for, when to use each one and more importantly when not to. https://dellenny.com/sharepoint-vs-teams-vs-onedrive-when-to-use-each-and-when-not-to/282Views1like0Comments
