# Microsoft 365 E3 30 Day License for 100 Users: Enterprise Microsoft 365 for a Short-Term 100-User Rollout Microsoft 365 E3 30 Day License for 100 Users is a 30-day subscription pack for 100 named users. The price is €6699.00, with digital delivery and a clear short-term tenant-pack position. This is not a perpetual Office license, not OEM, not MAK, not KMS, and not LTSC. It is subscription licensing for Microsoft 365 enterprise users, so the buyer should think in terms of tenant assignment, named users, admin control, service availability, and renewal timing rather than a one-time product key. The SKU is built for a defined project window: pilots, migrations, audits, training, seasonal staffing, proof-of-concept environments, or a temporary enterprise group that needs Microsoft 365 E3 capabilities without buying a normal annual seat block through standard procurement. It should be treated as a short-term commercial pack, not as a promise that Microsoft direct monthly terms, regional packaging, or Teams availability will match every tenant. ## What you get Microsoft 365 E3 provides enterprise productivity and cloud services for named users. Licensed users can work with the Microsoft 365 app family, Outlook, Word, Excel, PowerPoint, OneNote, Exchange, SharePoint, OneDrive, and Teams where available for the tenant and region. The plan also brings identity, compliance, security, and administration features that matter when the buyer is managing a real organisation rather than one personal account. The 100-user count is the key procurement unit. Each user who needs the service during the 30-day term must be covered. The license is user based, not device based. Users sign in with work or school accounts in a Microsoft tenant, and the tenant administrator is responsible for assignment, access policies, MFA, mailbox and file setup, and offboarding when the term ends. E3 is the enterprise middle tier for organisations that need more than Business Premium but do not need the full E5 security and analytics stack. It is stronger than Business Standard because it is built for larger tenant governance, compliance, and enterprise administration. The practical value is not just Word and Excel. The plan gives the organisation a controlled Microsoft 365 environment where identity, collaboration, mail, files, information protection, and admin policies can be managed together. That is very different from a cheap account listing or a perpetual Office 2024 key. ## What's new and what matters in this version Microsoft 365 changes continuously because it is a subscription platform. The current enterprise buying conversation is about secure collaboration, identity protection, data governance, and endpoint-aware productivity. Users expect current Office apps, browser access, mobile access, real-time co-authoring, and cloud files. Administrators expect MFA, conditional access patterns, auditability, sensitivity controls, secure sharing, and predictable assignment. For Excel-heavy teams, the Microsoft 365 app channel keeps modern spreadsheet capabilities available: dynamic arrays, XLOOKUP, LET, newer analysis functions, improved collaboration, and ongoing performance work. For document teams, Word and PowerPoint benefit from current collaboration and media workflows. For operations and management teams, Exchange, SharePoint, Teams, and OneDrive reduce the amount of business knowledge trapped in local files and unmanaged email attachments. E3 matters when the organisation has outgrown small-business administration but does not need every E5 component. It is a strong enterprise baseline for productivity, compliance, identity, and information protection. Buyers often choose E3 when Business Premium is too small-business oriented and E5 is more security stack than the project requires. Copilot is not included. Microsoft 365 Copilot requires separate eligible licensing and tenant readiness. Do not buy this SKU expecting AI features, Teams Phone configuration, or add-on security products unless they are explicitly included in the delivered activation scope. ## System requirements | Component | Requirement | | --- | --- | | License term | 30-day subscription pack | | User count | 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 | | Browser | Current Microsoft Edge, Chrome, Firefox, or Safari | | Internet | Required for activation, service access, admin, downloads, and subscription validation | | Administration | Tenant admin access required for assignment, policies, and offboarding | ## Comparison table | Category | Microsoft 365 E3 30-day pack | Microsoft 365 Business Premium | Office 2024 Professional Plus | | --- | --- | --- | --- | | Payment model | Short-term subscription | Annual subscription | One-time desktop license | | Best buyer | Enterprise project needing 100 users for 30 days | SMB needing apps plus security | Desktop Office users needing fixed release | | User scope | 100 named users | Business seat packs | Device or MAK volume scope | | Cloud services | Exchange, OneDrive, SharePoint, Teams where available | Exchange, OneDrive, SharePoint, Teams where available | Not included | | Security/admin | Enterprise Microsoft 365 E3 controls | SMB Intune and Defender controls | Not a cloud security plan | | Feature cadence | Current subscription channel | Current subscription channel | Fixed Office 2024 feature set | | Copilot included | No | No | No | | Best reason to choose | Temporary enterprise capability at scale | Ongoing SMB tenant | Perpetual desktop apps | ## Activation & licensing This is subscription licensing for named users. It is not a lifetime key and not a device-bound retail product. The purchaser should confirm the tenant, administrator, user list, regional requirements, and expected end date before activation. If the pack is being used for a project, decide whether users will keep their data after the 30-day term, whether mailboxes need migration, and who is responsible for export or retention. Compliance-sensitive buyers should document the commercial scope. Keep the order record, user assignment list, activation date, expiry date, admin owner, and any support correspondence. Do not assume transfer, downgrade, or renewal rights beyond the delivered instructions. Microsoft cloud packaging can vary by region, especially around Teams and enterprise add-ons, so check the activation path before changing production systems. ## Installation guide 1. Complete checkout and keep the digital order record. 2. Confirm the Microsoft tenant and administrator that will receive or manage the pack. 3. Prepare the 100-user assignment list before activation. 4. Review MFA, admin roles, domain, mailbox, and SharePoint requirements. 5. Assign licenses to named users through the supplied activation process. 6. Install Microsoft 365 apps on supported devices where desktop apps are required. 7. Validate Outlook, OneDrive, Teams where available, SharePoint, and browser sign-in. 8. Record the expiry date and offboarding plan before the 30-day term ends. ## Why buy here Enterprise Microsoft 365 pricing is difficult to compare because Microsoft direct pages normally show per-user monthly prices on annual commitments, while short-term reseller packs are priced as a delivered bundle. This listing separates those shapes. The compare-at value is tied to real Microsoft public RRP math, and the sale price is based on the supplied short-term pack cost, not on an invented discount. The practical advantage is procurement speed. A project lead can cover 100 users for a defined 30-day period. An IT team can test migration, security policy, collaboration structure, or training workflows without converting the whole organisation to a new annual agreement. A reseller or managed service buyer can document exactly which users were covered and for how long. The honest limitation is that 30-day enterprise licensing is not a substitute for a long-term Microsoft licensing strategy. If the organisation needs stable production service, renewal protection, formal support, and predictable monthly billing, a direct annual or CSP arrangement is cleaner. This SKU is strongest when the buyer has a defined temporary use case and understands tenant administration. One more procurement check is identity ownership. The buyer should decide whether the account or tenant belongs to the company, a project administrator, a managed service provider, or an end user. That decision affects password recovery, MFA prompts, mailbox access, audit records, and what happens when the user leaves. A low price does not remove the need for a clean owner. Data location and retention also matter. Before activation, decide whether files will live in OneDrive, SharePoint, local folders, or an existing document system. If the product is used for a temporary project, export requirements should be written down before the term starts. Waiting until the final day creates unnecessary risk because users may have created mailboxes, Teams chats, shared links, notebooks, and spreadsheets that need a controlled handover. Support expectations should be practical. Digital delivery can be fast, but Microsoft tenant setup is still real administration. DNS, domains, mail routing, MFA, app installation, browser sign-in, and mobile access can all depend on the customer's environment. The cleanest rollout starts with one test user, confirms activation, validates the included services, and only then assigns the remaining users. Finally, compare like with like. A one-user annual listing, a public Microsoft annual-commit price, a short-term tenant pack, and a full reseller-managed deployment are not the same commercial product. The right comparison includes duration, user count, region, Teams packaging, tax, support, renewal, and who performs tenant administration. That discipline prevents a cheap-looking offer from being mistaken for the wrong licensing model. For finance records, note whether the purchase is project expense, subscription expense, or customer delivery cost. The invoice should match the internal approval language so renewal, reordering, or chargeback work is not reconstructed later from emails. That is especially important for temporary licenses because the operational owner may be different from the buyer and support contact later on. When in doubt, document the intended user, intended term, and intended workload before the first sign-in happens at all. ## FAQ ### Is Microsoft 365 E3 a subscription? Yes.
