Common questions about Microsoft 365 E3
What's the difference between E3 and Office 365 E3?
Microsoft 365 E3 bundles Office 365 E3 + Enterprise Mobility & Security E3 + Windows 11 Enterprise E3 into a single license — a better deal than buying them separately.
Do we need to migrate mailboxes ourselves?
No. We handle mailbox migration from Exchange on-premises, Google Workspace, or another Microsoft 365 tenant — typically within one to two business weeks depending on volume.
Is Teams Phone included?
Teams is included. Teams Phone (the PBX add-on for calling the public phone network) is a separate license we can add per user as needed.
Do you offer volume pricing?
Yes. For 300+ seat commitments we offer volume-based discounts and annual billing terms. Tell us your user count in the quote form.
