## FAQ

### What is Microsoft Defender for Office 365 (Plan 1)?

Microsoft Defender for Office 365 (Plan 1) is a per-user security add-on for eligible education tenants, because it adds Microsoft’s Office 365 threat-protection capabilities without replacing a full Microsoft 365 suite. It is commonly used to protect faculty and student mailboxes against phishing, malware, malicious links, and unsafe attachments.

### What does Defender for Office 365 Plan 1 include for schools?

Defender for Office 365 Plan 1 includes Plan 1 add-on licensing for Microsoft’s Office 365 threat-protection category, because it is designed to add email and collaboration security to eligible users. Schools should validate the current Microsoft service description before rollout, especially for Safe Links, Safe Attachments, anti-phishing, spoof and impersonation protection, real-time detections, reporting, and policy-based protection.

### What is not included with Defender for Office 365 Plan 1 for Education?

Defender for Office 365 Plan 1 is not a mailbox, Office apps, Teams, OneDrive, SharePoint, or a Microsoft 365 suite license, because it is an add-on security product. It also is not a replacement for Microsoft Defender for Endpoint, Defender for Identity, Defender for Cloud Apps, backup, long-term archiving, eDiscovery, or broader compliance licensing.

### Do faculty and students need different Defender for Office 365 Plan 1 licenses?

Yes, Education pricing is listed through separate faculty and student SKUs, because Microsoft distinguishes faculty and student purchasing paths in the Education segment. Schools should confirm the correct user mix before ordering so faculty users, paid student users, and any Student use benefit users are licensed through the appropriate option.

### What is the Student use benefit SKU for Defender for Office 365 Plan 1?

The Student use benefit is a separate Education SKU for Defender for Office 365 Plan 1, because Microsoft lists it separately from paid faculty and student options. Eligibility should be confirmed before purchase or assignment, since Student use benefit rules depend on Microsoft’s current education licensing requirements and the institution’s qualifying licenses.

### Can a school buy Defender for Office 365 Plan 1 for only faculty and not students?

Yes, a school can license only the users that need the add-on, because Defender for Office 365 Plan 1 is sold per user. The institution should still review whether student protection is required for risk, policy, or eligibility reasons before limiting the purchase to faculty.

### Can a school buy Defender for Office 365 Plan 1 for only students and not faculty?

Yes, student users can be licensed separately where the Education student SKU or eligible Student use benefit applies, because Microsoft lists student-specific options for this product. IT Partner should validate the school’s Microsoft 365 or Exchange Online licensing first so the add-on is assigned only to eligible users.

### Does Defender for Office 365 Plan 1 include Microsoft Teams?

No, Defender for Office 365 Plan 1 does not include Teams, because it is a security add-on rather than a collaboration suite license. If users need Teams access, they must already have or separately acquire the appropriate Microsoft 365, Office 365, or Teams licensing.

### Does Defender for Office 365 Plan 1 protect Teams, SharePoint, or OneDrive content?

Defender for Office 365 Plan 1 is intended for Microsoft’s Office 365 threat-protection category, because it protects against threats in email and collaboration scenarios. However, exact feature behavior for Teams, SharePoint, OneDrive, Safe Links, and Safe Attachments should be checked against Microsoft’s current Defender for Office 365 Plan 1 documentation before rollout.

### Does Defender for Office 365 Plan 1 include Microsoft 365 Copilot?

No, Defender for Office 365 Plan 1 does not include Microsoft 365 Copilot, because Copilot is a separate product and licensing path. Defender for Office 365 Plan 1 can be part of the school’s security posture, but it does not grant Copilot usage rights.

### Is Defender for Office 365 Plan 1 required before buying Microsoft 365 Copilot for Education?

Not necessarily, because Copilot eligibility is governed by Microsoft’s Copilot prerequisites and the user’s underlying Microsoft 365 licenses, not by Defender for Office 365 Plan 1 alone. Schools should confirm Copilot prerequisites separately and treat Defender for Office 365 Plan 1 as an email and collaboration security add-on, not as a Copilot license.

### What underlying license is required before assigning Defender for Office 365 Plan 1?

A user generally needs an eligible Microsoft 365, Office 365, or Exchange Online mailbox environment before Defender for Office 365 Plan 1 can be useful, because the product protects Office 365 email and collaboration workloads rather than providing the mailbox itself. IT Partner should validate the institution’s existing licensing before ordering or assigning seats.

### How is Defender for Office 365 Plan 1 different from Defender for Office 365 Plan 2?

Defender for Office 365 Plan 1 is the lower-tier Office 365 threat-protection add-on, because Plan 2 includes additional advanced capabilities that should be compared before purchase. If the school needs verified Plan 2-only capabilities such as automated investigation and response, Attack Simulation Training, or deeper threat investigation tooling, it should compare Plan 1 with Plan 2 before ordering.

### Does Defender for Office 365 Plan 1 replace anti-spam and anti-malware settings already in Exchange Online?

No, Defender for Office 365 Plan 1 does not simply replace all existing Exchange Online Protection settings, because it adds additional threat-protection capabilities and policies on top of the Microsoft 365 mail security stack. Schools should review current mail flow, anti-phishing, Safe Links, Safe Attachments, spoofing, and impersonation policies during deployment.

### How quickly can a school get started with Defender for Office 365 Plan 1?

A school can usually start after the add-on licenses are purchased, assigned, and configured, because the product is delivered as a cloud service inside the Microsoft 365 tenant. The practical timeline depends on license validation, policy design, pilot users, mail security baselines, and any change-control requirements the institution follows.

### Do we need to migrate mailboxes to use Defender for Office 365 Plan 1?

No mailbox migration is included or automatically required by the license, because Defender for Office 365 Plan 1 is an add-on for protection rather than a mailbox migration service. If the school is moving from another email platform or hybrid configuration, mail flow and protection design should be reviewed separately.

### Can IT Partner take over our CSP licensing without email downtime?

Yes, a CSP relationship or reseller transition typically does not require moving the Microsoft 365 tenant or interrupting mail flow, because the services remain in the same Microsoft tenant. IT Partner should coordinate the transfer, confirm subscription timing, and ensure the Defender for Office 365 Plan 1 seats remain assigned during the change.

### Will moving Defender for Office 365 Plan 1 to IT Partner change Microsoft’s price or tenant services?

The tenant services should not change just because the CSP provider changes, because the Microsoft cloud tenant and assigned licenses remain the service foundation. Pricing and available billing options must still be confirmed in the live configurator at checkout, since final availability and billing terms are controlled there.

### What commitment and billing options are available for Education customers?

Education listings include month-to-month and annual commitment options for paid faculty and student SKUs, because Microsoft publishes separate Education purchasing paths for this product. Annual upfront is the lowest listed paid annual option compared with annual paid monthly in the current Education data, but the live configurator controls the actual available option at checkout.

### Can we cancel, reduce seats, or add seats later?

Seat additions are usually straightforward during the subscription term, because Defender for Office 365 Plan 1 is licensed per user. Reductions, cancellations, and renewal changes depend on the commitment term, billing option, and current Microsoft CSP rules, so schools should confirm the exact change window with IT Partner before ordering.
