Microsoft Defender for Office 365 (Plan 2) — Pricing, Plans & What's Included

Microsoft Defender for Office 365 Plan 2 is a Commercial Microsoft security add-on for protecting Microsoft 365 collaboration workloads from email and collaboration threats, because it is sold as a Defender for Office 365 licensing SKU rather than as a full Microsoft 365 suite. The Commercial catalog includes Plan 2, F2, and P2 Add On options, so buyers should select the SKU that matches their existing licensing and user population.

Defender for Office 365 Plan 2 does not by itself include mailbox hosting, Office desktop apps, Teams licensing, or a full Microsoft 365 suite, because the catalog item is for Defender for Office 365 licensing only. It also does not confirm that another subscription in your tenant lacks overlapping protection, so IT Partner should review your current Microsoft 365 licenses before you buy.

Defender for Office 365 commercial SKUs are normally assigned to users who need the protection, because Microsoft 365 security services are typically licensed around user entitlements. Before quoting or deploying, confirm the current unit of measure and assignment rules from Microsoft licensing documentation, especially if you are protecting shared, service, or frontline-user scenarios.

Plan 2 is the standalone Commercial Defender for Office 365 Plan 2 catalog option, F2 is a related frontline-style Defender for Office 365 option, and the P2 Add On is intended to be added to qualifying base licensing. The right choice depends on your current Microsoft 365 licenses, because buying an add-on without the required base entitlement can create a licensing mismatch.

Yes, you should verify qualifying base-license eligibility before buying the P2 Add On, because the catalog identifies it as an add-on rather than a standalone replacement for all underlying Microsoft 365 services. IT Partner should check your tenant’s current licenses before checkout to avoid purchasing an add-on that cannot be properly assigned or used.

Microsoft commonly positions Defender for Office 365 Plan 2 as the advanced plan for Office 365 threat protection, because it is associated with capabilities such as advanced investigation, response, and simulation features. However, feature packaging can change by Microsoft service update and tenant cloud, so confirm the exact Safe Links, Safe Attachments, anti-phishing, impersonation, Explorer, automated investigation and response, and attack simulation entitlements against current Microsoft documentation before relying on any specific capability.

Defender for Office 365 can include protections that apply to collaboration scenarios such as links shared in Microsoft 365 services, because Microsoft positions it beyond basic email filtering. It does not include a Teams license, and Teams-specific protection behavior should be confirmed in current Microsoft documentation for your tenant cloud and configuration.

No, Defender for Office 365 Plan 2 should not be treated as including Microsoft Copilot, Microsoft 365 Copilot, or Microsoft Security Copilot, because those are separate products or add-ons with their own licensing requirements. Defender for Office 365 may provide security signals used across the Microsoft ecosystem, but Copilot licensing must be evaluated separately.

No, Defender for Office 365 Plan 2 is primarily a security protection license, because it is designed for threat protection rather than to serve as a standalone compliance, eDiscovery, or data residency entitlement. Data location and compliance outcomes depend on your Microsoft 365 tenant, tenant cloud, configuration, and other compliance licenses, so confirm residency and regulatory requirements before purchase.

A Government organization should not assume the Commercial SKU is appropriate for GCC, GCC High, or other government cloud requirements, because government tenants often require separate segment-specific offers and cloud availability. If residency, sovereign cloud, or compliance boundary requirements matter, validate the Government catalog option instead of buying the Commercial SKU.

A nonprofit should check Charity eligibility before buying the Commercial SKU, because Microsoft’s nonprofit programs can have different eligibility rules, offers, grants, and pricing structures. The source catalog shows Charity as a separate segment, so IT Partner should validate nonprofit status and the best available offer before placing a Commercial order.

An education customer should not automatically use the Commercial SKU for students or faculty, because Microsoft Education licensing often separates student and faculty/staff eligibility and may include different catalog options. The source catalog includes Education as a separate segment, so the buyer should validate the correct Education SKU and user category before purchasing.

You start by confirming the correct SKU, term, and user population, then purchasing and assigning the licenses in the Microsoft 365 tenant. After provisioning, policies and security settings still need to be configured or reviewed, because buying the license alone does not guarantee the desired protection posture is enabled exactly as intended.

Yes, many customers move to Plan 2 when they need more advanced Defender for Office 365 capabilities, because Plan 2 is positioned as the higher Defender for Office 365 plan. The licensing change is usually not a mailbox migration, but you should review policies, assignments, and any overlapping entitlements from existing Microsoft 365 plans before switching.

Yes, a tenant can often contain multiple Microsoft 365 license types, because different users may have different roles and base-license eligibility. You should only mix Plan 2, F2, and P2 Add On after confirming assignment rules, qualifying base licenses, and whether F2 is appropriate for the intended user scenario.

A CSP reseller change or new CSP purchase normally does not move mailbox data or reconfigure the Microsoft cloud service by itself, because the tenant and Microsoft 365 workloads remain in Microsoft’s cloud. IT Partner should still coordinate timing, license overlap, and assignments so users do not lose coverage during the transition.

No, IT Partner sells the Microsoft CSP catalog offer rather than a separate security product, because Defender for Office 365 is provisioned in the customer’s Microsoft tenant. Invoice totals can still depend on current CSP price lists, taxes, billing terms, promotions, and partner discounts, so confirm the commercial details before transferring.

The Commercial catalog includes monthly commitment with monthly billing, annual commitment paid upfront, and annual commitment billed monthly for Plan 2, because Microsoft CSP offers separate term and billing combinations. For the same SKU, annual commitment paid upfront has a lower listed annual total than annual commitment billed monthly, while monthly commitment provides the shorter commitment.

CSP cancellation rights depend on Microsoft’s New Commerce rules, because subscription changes are governed by the selected term and Microsoft’s cancellation window. In general, monthly commitment is the more flexible option, while annual or multi-year commitments are harder to cancel after the allowed cancellation period; confirm the exact rule before placing the order or renewal.

You can generally add seats during the subscription term, because Microsoft CSP subscriptions support increasing quantities as needs grow. Reducing seats is more restricted and is typically allowed only during the applicable cancellation window or at renewal, so choose the initial seat count carefully and ask IT Partner to confirm current CSP rules before purchase.
