Biza Email vs Microsoft 365 — for teams who don't need the Office bundle
Microsoft 365 Business Basic is $6/user/month — $72/user/year. Biza Email is $50/year flat for unlimited mailboxes. If you're not using Word, Excel, PowerPoint, and Teams daily, the math is one-sided.

Honest take
If you need Office, stay on Microsoft 365
Word, Excel, PowerPoint, Teams, and SharePoint are the reason most teams pay the Microsoft tax. If your finance team lives in Excel, the bundle is reasonable.
- Desktop Word / Excel / PowerPoint (Business Standard tier)
- Microsoft Teams video and chat
- SharePoint and OneDrive for documents
- Tight integration with Windows desktop and Active Directory
The case for switching
When you only need email, you only pay for email
If your team's working in Notion, Linear, Slack, or Google Docs, Microsoft 365 is paying for a stack you don't use. Biza Email ships the email part.
- Flat $50/year vs $6/user/month — meaningful savings past 8 users
- Unlimited mailboxes per domain, no seat-tier renegotiations
- EU data residency available for customers who need it
- Standard IMAP / SMTP — works with every mail client, including Outlook
Migration
Most teams migrate from Microsoft 365 in a week
Microsoft 365 exposes IMAP for mailbox export. Our migration tooling handles the import cleanly.
- Guided DNS handoff — MX, SPF, DKIM, DMARC
- IMAP-based mailbox import preserves folders, categories, read state, attachments
- Run both providers in parallel during cutover
- Outlook clients keep working — Biza Email speaks the same IMAP / SMTP Outlook uses for M365
Frequently asked: Biza Email vs Microsoft 365
Can my team keep using Outlook?
Yes. Biza Email speaks standard IMAP and SMTP, which is how Outlook talks to Microsoft 365 today. Configuration is straightforward — your team keeps the same Outlook app, pointed at Biza Email instead.
What about Teams and SharePoint?
Those aren't part of Biza Email. If Teams is your primary communication tool, Microsoft 365 makes sense. If you've moved to Slack, Discord, or Linear for communication and Notion or Google Docs for documents, Microsoft 365 is paying for tools you don't open.
Does Biza Email integrate with Active Directory?
Indirectly, via SAML 2.0 or OIDC SSO. If your AD environment exposes a SAML / OIDC endpoint — Microsoft Entra, Okta, or another federation layer — Biza Email works with it. We don't directly join an on-premises AD.
