About the M365 Administrator AI
The Teksolvr M365 Administrator AI is an enterprise-grade Microsoft 365 Solutions Architect and Zero Trust Cloud Identity Engineer with 15+ years of simulated operational experience. Powered by domain-trained AI models, this assistant guides administrators through Microsoft Entra ID governance, Exchange Online mail security (SPF/DKIM/DMARC), SharePoint & Teams governance, Microsoft Purview DLP and sensitivity label design, Intune MAM BYOD policy deployment, Defender XDR KQL threat hunting, Microsoft Copilot oversharing prevention, multi-tenant GDAP management, cross-tenant synchronization, and hybrid identity troubleshooting — all backed by production-ready Microsoft Graph PowerShell SDK scripts with certificate-based authentication, proper pagination, and HTTP 429 throttling handling.
Key Capabilities
Microsoft Entra ID & Zero Trust
Design Conditional Access policies with phishing-resistant MFA, configure Privileged Identity Management (PIM) for JIT role activation, scope delegated admin access via Administrative Units, and create quarterly Access Reviews using Microsoft Graph PowerShell SDK.
Microsoft Graph PowerShell SDK & REST API
Generate production-ready automation scripts using modern Microsoft.Graph cmdlets (never deprecated MSOnline/AzureAD). All scripts include certificate-based App Registration authentication, -All pagination, and HTTP 429 throttling retry logic with Start-Sleep backoff.
Exchange Online, Mail Flow & Defender for Office 365
Diagnose SPF/DKIM/DMARC alignment failures, configure Safe Links and Safe Attachments, enforce DMARC p=reject, audit SPF lookup limit (max 10 mechanisms), and design transport rules using Exchange Online v3 module cmdlets.
Microsoft Purview DLP, Sensitivity Labels & eDiscovery
Create multi-location DLP policies targeting Sensitive Information Types (Credit Card, SSN, IBAN) using New-DlpCompliancePolicy in audit-only mode first, design a sensitivity label taxonomy (Public → Top Secret), apply Preservation Lock for regulatory records, and run eDiscovery Premium searches with custodian legal holds.
Intune MAM BYOD & Device Compliance
Deploy App Protection Policies for unmanaged BYOD iOS and Android devices (PIN enforcement, cut/copy/paste blocking, jailbreak detection, data backup restrictions) via Graph API. Configure device compliance policies requiring BitLocker and Secure Boot. Debug Autopilot enrollment errors (0x80180018, 0x80070002).
Defender XDR Threat Hunting (KQL & MITRE ATT&CK)
Write production KQL queries for DeviceProcessEvents, CloudAppEvents, and IdentityLogonEvents to detect encoded PowerShell execution (T1059.001), BEC inbox forwarding rules (T1114.003), ransomware mass file renames (T1486), LSASS credential dumping (T1003.001), and impossible travel sign-ins (T1078).
GDAP Multi-Tenant CSP/MSP Management
Replace legacy Delegated Admin Privileges (DAP) with Granular Delegated Admin Privileges (GDAP) scoped to least-privilege Entra ID roles per customer tenant. Manage relationships via Partner Center API/Graph, implement PIM for Groups for JIT customer-tenant access, and automate GDAP expiry monitoring.
Cross-Tenant Synchronization (Mergers & Acquisitions)
Configure Entra ID Cross-Tenant Synchronization for post-merger identity consolidation: enable inbound sync via crossTenantSyncPolicy, map attributes (UPN, department, companyName), configure GAL visibility (showInAddressList), monitor provisioning errors via Get-MgAuditLogProvisioning, and govern synced B2B accounts via Lifecycle Workflows.
