Microsoft 365 E3 - 30 Day License, 100 Users

# Buy Microsoft 365 E3 30 Day License for 100 Users on Lizensa

A team can need serious Microsoft 365 capacity for a short window without wanting a year-long commitment on day one. Microsoft 365 E3 - 30 Day License, 100 Users is for EU SMEs, consultants, training teams, audit groups, migration testers and temporary project offices that need a defined Microsoft 365 Enterprise subscription for one month. It gives 100 named users a practical E3 environment for current Office apps, cloud files, business email, collaboration and enterprise administration features.

This is a subscription pack, not a perpetual Office key. It is not OEM, not MAK volume activation, not KMS, not LTSC and not a single code for unlimited people. Buy it when the work has a clear start date, user list and expiry plan. If you need a smaller long-term SME plan, compare [Microsoft 365 Business Premium](/products/microsoft-365-business-premium). If you need advanced E5 security for a larger group, compare [Microsoft 365 E5 30 Day License for 200 Users](/products/microsoft-365-e5-30-day-license-200-users). For fixed desktop Office without Microsoft 365 services, see [Microsoft Office 2024 Professional Plus MAK](/products/microsoft-office-2024-professional-plus-mak-100-users), [Microsoft Office 2024 Home & Business](/products/microsoft-office-2024-home-and-business-for-windows-mac) or the [Microsoft 365 category](/categories/microsoft-365).

## What You Get

You receive digital delivery information and activation guidance for a 30-day Microsoft 365 E3 subscription covering 100 named users. The practical scope is tenant-based Microsoft 365 Enterprise access through work or school accounts. The administrator assigns licenses to people, not devices. Each person who needs the service during the term should be included in the 100-user plan.

Microsoft 365 E3 gives eligible users current Microsoft 365 apps such as Word, Excel, PowerPoint, Outlook and OneNote on supported devices, plus cloud and tenant services including Exchange, OneDrive, SharePoint and Teams where Microsoft packaging, region and tenant context make Teams available. It also includes enterprise identity, information protection, compliance and administration capabilities that matter when a group must be managed centrally rather than as separate personal accounts.

The important buyer detail is the 30-day term. This SKU is useful for a migration rehearsal, client handover month, short compliance review, seasonal workforce, classroom, event team, tender room or pilot tenant. It is not meant to replace a durable licensing plan for daily production over the next year. Before activation, decide who owns the tenant, who will assign users, where files and mailboxes will live, and what happens when the term ends.

This purchase does not automatically include Microsoft 365 Copilot, Teams Phone, Windows licenses, server licenses, managed migration labor, backup services, domain registration, custom SharePoint design or unlimited administrator support. Keep the Lizensa order confirmation, GDPR-conscious invoice email, delivery email, activation date, tenant name, administrator contact and assigned-user list together for VAT, warranty, internal approval and support.

For a consumer or small business buyer, the simplest check is purpose. Write down whether the pack is for training, migration, audit, testing or temporary staff. If the answer is ongoing everyday operation, choose a long-term Microsoft 365 plan instead of relying on a one-month SKU.

## What's New

Microsoft 365 E3 is not a frozen desktop release. It follows the Microsoft 365 subscription model, so the value is current productivity, cloud collaboration and central control. Excel users benefit from modern spreadsheet work such as dynamic arrays, XLOOKUP, LET, co-authoring and continuing performance improvements. Word and PowerPoint users get current collaboration, commenting, accessibility and cloud-file workflows. Outlook, Exchange, OneDrive and SharePoint reduce the need to move business knowledge through local files and unmanaged attachments.

E3 is the middle enterprise step. It is more tenant-oriented than Microsoft 365 Business Standard and more enterprise-focused than many SMB plans, but it does not include the full E5 security, analytics and voice stack. That makes it attractive when a project needs enterprise governance and productivity for 100 users, while the budget or risk profile does not justify E5.

Copilot should not be assumed. Microsoft 365 Copilot requires separate eligible licensing and tenant readiness. Teams availability can also vary in the EU and other regions because Microsoft packages collaboration services differently by market and commercial route. Check the delivered activation path before planning meetings, phone workflows or compliance-sensitive changes around this short subscription.

## System Requirements

| Component | Requirement | | --- | --- | | License term | 30-day Microsoft 365 subscription | | User scope | 100 named users | | Account type | Microsoft work or school accounts in a tenant | | Desktop apps | Supported Windows and macOS versions for current Microsoft 365 apps | | Mobile apps | Supported iOS and Android versions where available | | Browser | Current Microsoft Edge, Chrome, Firefox or Safari | | Internet | Required for activation, downloads, cloud services and subscription validation | | Administration | Tenant administrator access for assignment, policy choices and offboarding |

Treat this table as an operational checklist. A license can be valid while the rollout still fails because the wrong person owns the tenant, the domain is not ready, MFA is unclear, users are missing, or files have no retention plan. For a 30-day project, those decisions should happen before activation, not on the last afternoon of the term.

## Comparison

| Option | Best For | Check Before Buying | | --- | --- | --- | | Microsoft 365 E3 30-day, 100 users | Temporary enterprise productivity and administration for a defined group | Tenant owner, 100-user list, expiry plan and Teams availability | | Microsoft 365 E5 30-day, 200 users | Larger temporary projects needing advanced security, compliance and analytics | Higher scope, larger user count and more policy planning | | Microsoft 365 Business Premium | Ongoing SME productivity with security and device management | Intended for smaller business tenants, not a one-month enterprise pack | | Office 365 Account annual license | One user needing a simpler annual Microsoft 365-style account | Not a 100-user enterprise tenant plan | | Office 2024 Professional Plus MAK | Desktop Office without cloud services or subscription term | No Exchange, OneDrive, SharePoint or Teams services |

Choose E3 when the work needs Microsoft 365 services, named-user assignment and enterprise administration, but only for a short period. Choose Business Premium when a small company wants ongoing apps, mail, device management and Defender for Business. Choose E5 when security operations, advanced compliance or analytics are the reason for the purchase.
