Microsoft 365 Administration & Support
Your M365 Team, Under One SOW
Full-tenant Microsoft 365 administration — licensing, identity, endpoints, Exchange, SharePoint, Teams, Copilot, and security — delivered by ICS as delegated Primary Admin / CPOR under our Microsoft Modern Work Solutions Partner designation. Fixed monthly fee, documented RACI, ticket-backed operations, monthly reporting.
Co-Managed or Fully Managed
Your internal capacity, compliance obligations, and growth trajectory determine the right model. Most clients start with a tenant assessment, and we scope from there.
Co-Managed A&S
Your internal team keeps admin access and owns day-to-day operations. ICS operates as delegated Primary Admin for defined workloads, providing architecture depth, escalation, and after-hours coverage under a documented RACI.
Fully Managed A&S
ICS holds delegated Primary Admin / CPOR and owns the tenant end-to-end — licensing, identity, endpoints, Exchange, SharePoint, Teams, Copilot, and security — under a fixed monthly fee, ticket-backed operations, and monthly reporting.
The Full Microsoft 365 Stack, Under One SOW
Every layer of the tenant — from licensing through Copilot — owned, measured, and reported on monthly. License Management and Security & Messaging Administration are included, not upsold.
Licensing & Tenant Administration
License Management (L1) is included in A&S — SKU optimization, CSP billing reconciliation, true-ups, and quarterly utilization audits, with no separate purchase required.
Identity & Access (Entra ID)
Entra ID tenant hardening, Conditional Access, MFA enforcement, privileged identity management (PIM), and guest/B2B governance across the full user population.
Endpoint Management (Intune)
Microsoft Intune deployment or co-management, Autopilot provisioning, cross-platform device policy, and hybrid Entra join for organizations with on-prem infrastructure.
Exchange Online, Teams & Security/Messaging
Security & Messaging Administration (L2) is included in A&S — Defender for Office 365, mail flow, DLP, anti-phishing, and Teams policy, all under one SOW.
SharePoint & OneDrive Governance
Information architecture, sensitivity labels, DLP, external sharing controls, retention policy, and Copilot-ready permissions remediation.
Microsoft Security Stack
Defender for Endpoint, Defender for Cloud Apps, and Microsoft Sentinel — deployed, tuned, and monitored as part of full-tenant operations.
Copilot Readiness & Rollout
Permissions remediation, sensitivity labeling, license fit modeling, pilot design, and adoption measurement — delivered as part of ongoing tenant operations, not a separate project.
Compliance & Audit Support
Microsoft Purview configuration, SOC 2 / HIPAA / GLBA / PCI DSS evidence packaging, and audit-ready documentation, maintained continuously rather than assembled reactively.
L1 and L2 are already in your A&S engagement
A&S includes License Management (L1) and Security & Messaging Administration (L2) — you don't need to purchase them separately when engaging A&S. Licensing governance and the security/messaging plane are delivered as part of the same fixed monthly fee and the same RACI.
From Tenant Audit to Managed Operations
A predictable 8-week path from first conversation to fully operational A&S coverage. Every gate has a written deliverable so you know what you're getting.
Tenant Assessment
Fixed-fee tenant operations assessment — licensing audit, security baseline, identity posture, Exchange/Teams/SharePoint governance review, and prioritized remediation roadmap.
Stabilize
Close the highest-severity gaps — Conditional Access, MFA coverage, privileged access, backup, license cleanup — before ICS assumes ongoing delegated admin responsibility.
Transition to A&S Operations
RACI finalized, runbook handoff, monitoring integration, ticket routing, escalation paths defined, and the first monthly business review scheduled.
Ongoing Operations + QBRs
Ticket-backed daily operations, monthly reporting against the RACI, quarterly business reviews, and annual license and security posture optimization.
Scoped Engagements. Monthly Retainers. No Surprises.
Tenant assessments and onboarding are fixed-fee with written deliverables. Ongoing co-managed and fully managed A&S operations run on a monthly retainer scoped to your user count, security posture, and workload complexity — inclusive of licensing and security/messaging. Every proposal is written, reviewed with you, and signed before work starts.

What does A&S mean and how is it different from Microsoft 365 Management generally?+
A&S stands for Administration & Support — the ICS designation for full-tenant Microsoft 365 operations delivered as delegated Primary Admin / CPOR (Cloud Partner of Record). It's the same practice you'd find under our general Microsoft 365 management offering, positioned specifically as one of four independently purchasable tiers in the ICS M365 stack, sitting above License Management (L1) and Security & Messaging Administration (L2).
Do we need to separately buy License Management or Security & Messaging Administration?+
No. A&S includes License Management (L1) and Security & Messaging Administration (L2) — you don't need to purchase them separately when engaging A&S. Licensing governance and the security/messaging plane are folded into the same SOW and the same monthly fee.
Do you offer co-managed Microsoft 365 services or only fully outsourced admin?+
Both. Co-managed is our most common engagement — your internal team keeps admin rights and owns daily operations, and ICS provides architecture depth, escalation, security engineering, and after-hours coverage under delegated Primary Admin for specific workloads. Fully managed is available for organizations without a dedicated M365 administrator.
What is the M365 A&S Specialist designation?+
Microsoft 365 Administration & Support Specialist is a Microsoft partner-level recognition reflecting demonstrated depth in M365 lifecycle management, security, and compliance. ICS holds this designation alongside Microsoft Modern Work Solutions Partner status, and renews both against Microsoft's current technical and customer-evidence requirements.
How do you handle identity and Entra ID tenant hardening?+
Every A&S engagement starts with an Entra ID posture review — Conditional Access coverage, MFA enforcement, privileged identity management (PIM), legacy authentication, break-glass accounts, and guest/B2B governance — with a fixed-scope hardening accelerator available before transitioning to ongoing operations.
Can you help us prepare for Microsoft 365 Copilot?+
Yes. Copilot rollout requires SharePoint permissions remediation, sensitivity labels, license fit analysis, and change management — all part of the standard A&S scope. We handle readiness, pilot, and full rollout with adoption measurement, without a separate statement of work.
How do you price ongoing A&S engagements?+
Onboarding and assessment engagements are fixed-fee with defined deliverables. Ongoing co-managed and fully managed A&S operations are scoped as a single monthly retainer based on user count, security posture, and workload complexity — inclusive of licensing and security/messaging administration.
Will you work with our existing Microsoft partner or CSP?+
It depends on scope. If you want ICS to run A&S end-to-end, we typically also become CSP of record — no transition fees. If you have a separate CSP relationship you want to preserve for billing only, we can scope A&S around it, though most clients find consolidating under one SOW simpler to govern.
Ready for a Microsoft 365 You Don't Have to Worry About?
Start with a tenant assessment. Two weeks, fixed fee, written deliverable. Then decide whether co-managed or fully managed A&S is the right model for you.
