Microsoft's top-tier Office 365 suite, combining full desktop, web, and mobile Office apps with HD video conferencing, 1TB personal storage, advanced analytics, and enterprise-grade security — everything in E5, minus dial-in audio conferencing for Teams meetings.
A device and identity management bundle combining Entra ID P1 (SSO, MFA, Conditional Access), Microsoft Intune (mobile device and app management), and Azure Information Protection P1 (document encryption and rights management). The foundational security layer included in Microsoft 365 E3, giving organisations control over how corporate data is accessed and shared across devices.
Builds on EMS E3 with advanced identity and threat protection: Entra ID P2 (risk-based Conditional Access, Identity Protection, Privileged Identity Management), Azure Information Protection P2, and Microsoft Defender for Cloud Apps. The more comprehensive security tier included in Microsoft 365 E5, adding proactive, automated threat detection and governance on top of E3's baseline controls.
Upgrades an existing Microsoft Entra ID P2 subscription to the full Entra Suite. Adds Entra ID Governance, Private Access (ZTNA/VPN replacement), Internet Access (secure web gateway), premium Verified ID features (including Face Check), and advanced Identity Protection — a complete cloud-based solution for securing workforce access across cloud and on-premises resources.
The foundational cloud-based business email service, providing a 50GB mailbox per user with shared calendars, contacts, and Exchange Online Protection (anti-spam and anti-malware). Accessible via Outlook desktop, web, and mobile — a solid choice for organisations that don't need advanced compliance features like litigation hold or unlimited archiving.
Builds on Plan 1 with a larger 100GB mailbox and unlimited auto-expanding archive (up to 1.5TB), plus advanced compliance features like litigation hold, In-Place Hold, Data Loss Prevention, and Cloud Voicemail. Suited to larger organisations or those with stricter data retention and compliance requirements.
An add-on that gives eligible Exchange Online users (Plan 1, Business Basic/Standard, or F3) a separate cloud archive mailbox with auto-expanding storage (starting at 100GB, growing up to 1.5TB), plus In-Place Hold and Litigation Hold. A cost-effective way to add unlimited archiving and legal hold without upgrading to Exchange Online Plan 2.
Microsoft's most affordable email licence, providing a 2GB mailbox with basic email, calendar, and contacts — accessed via Outlook on the web or mobile only, with no desktop client. Suited to deskless or shared-device workers who need light email access rather than a full mailbox experience.
Provides always-up-to-date desktop, web, and mobile versions of Word, Excel, PowerPoint, and Outlook (desktop client only, no hosted mailbox), plus 1TB of OneDrive storage per user, installable across up to 5 devices. Suited to SMBs (up to 300 users) that need the core Office apps without email hosting, Teams, or collaboration tools — those require Business Standard or Premium.
An add-on that gives Teams meeting organisers dial-in phone numbers for their meetings — letting participants join by calling a landline or mobile instead of using the Teams app. Useful for attendees travelling or with poor internet connectivity; assigned to meeting organisers only, as dial-in attendees don't need a licence.
An entry-level productivity suite for small and medium businesses (up to 300 users), providing web and mobile versions of Word, Excel, and PowerPoint alongside business email (Exchange), Microsoft Teams, OneDrive, and SharePoint. Suited to organisations that mainly need cloud-based collaboration tools without the full desktop Office apps.
