Add-in without Connected Experience
I've developed an Outlook Add-in using the new web tech based approach (not a legacy COM Plugin). One of our customers wants to use said Add-in, but they have the requirement that they can't enable the "Connected Experience" for their Outlook. Is it possible in any way to use an Outlook Add-in without having to enable the "Connected Experience" or is this just not an option?
Outlook for Android not syncing contacts automatically
Hi Everyone, I can't get Outlook on my android phone (Samsung S9) to sync contact automatically with my Exchange (Microsoft Hosted Exchange) account. If I add a contact on the Outlook app running on my Windows 10 laptop, I can see it if I look on the Outlook for web. I have checked the usual settings on my phone: The only way to get the contacts to update is to reset the account: Contacts that I add on my phone (Exchange account) do not sync back to the online account. Outlook on my phone syncs emails with the same account normally. I've tried clearing data / cache, and even taken the extra step of uninstalling and reinstalling on my phone but it makes no difference Any suggestions gladly welcomed!

Increasing Microsoft Graph Per-Mailbox Throttling Limits (PUT/POST/PATCH & Concurrency)
I am referring to the per-mailbox throttling limits documented here: https://learn.microsoft.com/en-us/graph/throttling-limits#limits-per-mailbox Specifically: 150 MB limit for PUT/POST/PATCH requests within a 5-minute window 4 concurrent requests per mailbox In a multi-tenant SaaS application scenario, these limits can become restrictive when processing large volumes of mailbox data. I would like clarification on the following: Is it possible to request an increase in these per-mailbox limits through Microsoft (e.g., via support or a formal quota increase request)? Are there recommended architectural patterns or best practices to efficiently handle high-throughput scenarios while staying within these limits? Can tenant administrators (our customers) configure or influence these limits through Microsoft 365 admin settings? Any official guidance or recommendations would be highly appreciatedClassic Outlook: The People Card Is Not Retiring, Just the Expanded View
One part of this Classic Outlook update could easily confuse people, so it is worth clearing up. In June 2026, Microsoft is retiring the People Card Expanded View in Classic Outlook. The full People Card is not going away. Users will still be able to open the standard contact card. What is changing is the expanded view, which gives users a little more context and a few extra details in one place. It may seem like a small change at first, but these types of updates can still affect how users look up contact information and move through their daily work. I put together a full blog post that explains what is changing, what stays, and where users can still get the richer contact experience.

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.
