Enterprise productivity + security + Windows + device management Large organizations needing full Office suite, Windows Enterprise, identity protection, and compliance It's priced at $36.00/user/month on an annual commitment and has no user limit.
What's the difference between M365 E3 and M365 E5?+

Microsoft is rebalancing M365 pricing globally starting July 1, 2026. M365 E3 moves from $36.00 to $39.00/user/mo — a 8% increase. Locking in an annual commitment before July 2026 holds your current rate for the full term.

Can I mix M365 E3 with other Microsoft 365 plans in the same tenant?+
Yes — Microsoft fully supports mixed licensing. Most cost-optimized tenants have a mix: executives on E5, knowledge workers on E3 or Business Premium, frontline staff on F3. Our license calculator can model your blend.
What is Microsoft 365 E3?
Microsoft 365 E3 is a enterprise-grade Microsoft 365 subscription plan priced at $36/user/month (annual commitment). It supports unlimited users and includes 1-5+ TB OneDrive of cloud storage per user.
Best for: Large organizations needing full Office suite, Windows Enterprise, identity protection, and compliance
This plan includes 61 features across 13 categories including Office Apps, Email & Calendar, Collaboration, Storage, Employee Experience. It does not include 17 features available in higher-tier plans.

Free trial: M365 E3 offers a 30-day free trial (credit card required).
Switching to M365 E3?
Enterprise rollouts of M365 E3 often involve migrating thousands of mailboxes from on-premises infrastructure. If your organization is running Exchange Server 2016 or 2019, our on-premises Exchange to Office 365 migration service uses hybrid connectivity to move mail, calendars, and public folders with zero user disruption. For older Exchange 2013 environments, we handle the staged migration path that Microsoft recommends for large mailbox counts.
Consolidating multiple M365 tenants after a corporate acquisition? Cross-tenant mailbox migration is one of the most complex M365 projects. Our Microsoft 365 tenant-to-tenant migration team has handled mergers involving 5,000+ mailboxes — including Teams channels, SharePoint document libraries, OneDrive data, and Entra ID identity mapping.
Organizations making the switch from Google Workspace at the enterprise level face additional complexity around shared drives, Google Vault data, and Google Groups. Moving from Gmail to Outlook and Google Drive to OneDrive requires careful planning around permissions, retention policies, and user retraining. We run a parallel-operations period so teams can access both platforms during the transition. For a broader view of what is involved, see our complete Microsoft 365 migration services overview.
