Best Microsoft 365 Alternatives for Business in 2026
Eight ways to run mail, files, documents, chat and calls without a Microsoft 365 tenant, compared on what they cost per user, what they include, where the data lives and who each one is for. We sell one of them, MassiveGRID's Nextcloud Hub, and say so; the others are rated as honestly as we can.
Why teams look beyond Microsoft 365
Price. On 1 July 2026 Microsoft raised Business Basic from about $6 to $7 and Business Standard from about $12.50 to $14 per user per month, with Business Premium staying at about $22; existing customers see it at their next renewal. Add Copilot, compliance add-ons and the Teams unbundling in Europe and the bill is hard to predict. Our price increase page works through what it means for a 20-person company.
Data location and sovereignty. Microsoft chooses the regions. The EU Data Boundary helps European tenants, but the regions are still Microsoft's, US law still reaches a US company's data, and a growing number of European public bodies have concluded that is not enough. The European alternative page is for them.
Dependence. A company that lives in SharePoint, Teams and the Power Platform discovers at renewal time how hard it is to leave. Open standards are the cure, and most of the alternatives below speak them.
The alternatives at a glance
| Alternative | What it is | Per user per month | Data region | Apps | Best for |
|---|---|---|---|---|---|
| MassiveGRID Nextcloud Hub | Managed Nextcloud Enterprise, per user | $5.90 to $19.90 | U.S., E.U., U.K. or Asia, your choice | Files, Office, Talk, mail, calendar, contacts; Deck, Tables, Notes from Business | Teams of 1 to 50 that want the suite with the data where they choose; dedicated instances beyond |
| Google Workspace | SaaS suite | About $7 to $22 | Google's regions | Gmail, Drive, Docs, Meet, Calendar | Teams that want the other big suite and accept provider-chosen regions |
| Zoho Workplace | SaaS suite | About $3 to $7 | Zoho's regions (EU, US, India and others) | Mail, WorkDrive, Writer, Sheet, Cliq, Meeting | Price-sensitive teams happy with a smaller ecosystem |
| Proton for Business | Encrypted mail and drive, SaaS | About $7 to $20 | Switzerland and EU | Mail, Calendar, Drive, VPN, Pass; Docs in Drive | Teams whose priority is end-to-end encrypted mail |
| openDesk | Open-source suite for public bodies (built partly on Nextcloud) | Via partners and ZenDiS; by deployment | Your datacenter or a partner's | Files, Office, mail, chat, video, projects | German and European public administrations |
| ONLYOFFICE Workspace / DocSpace | Office-centric collaboration, self-hosted or SaaS | Per admin or per tenant; check vendor | Self-hosted or vendor cloud | Documents, DocSpace rooms, mail and CRM in Workspace | Teams whose work is documents first |
| Zimbra | Mail and calendar server, licensed via partners | Per mailbox via partners | Self-hosted or partner-hosted | Mail, calendar, contacts, chat | Organisations replacing Exchange only |
| Self-hosted Nextcloud | You run it | Server cost only | Anywhere | Everything Nextcloud offers | Teams with a Linux administrator and time |

Each one in a paragraph
1. MassiveGRID Nextcloud Hub
Managed Nextcloud Enterprise priced per user, with Nextcloud Office, Talk, a mailbox, calendar and contacts on every plan, in the U.S., E.U., U.K. or Asia at your choice, from $5.90. The honest limits: no custom domain on the shared platform (that is a dedicated instance), 50 users per online order, and Nextcloud Office is not desktop Excel. Our plan-by-plan comparison says where Microsoft still wins.
2. Google Workspace
The other big suite: Gmail, Drive, Docs, Meet and Calendar at about $7, $14 and $22 after Google's 2025 increase, with Gemini bundled. It solves the licence-complexity problem and not the data-location one, since Google also chooses the regions. The right answer for a company whose objection to Microsoft is the product, not the model.
3. Zoho Workplace
Cheap and complete: mail, WorkDrive, an office suite, Cliq chat and Meeting, from roughly $3 to $7 per user on annual billing. Zoho runs its own datacenters in several regions and has no advertising business. The ecosystem is smaller and the office apps are good rather than great.
4. Proton for Business
End-to-end encrypted mail, calendar and drive from Switzerland, from about $7 to $20 per user. Strongest on mail privacy, weakest on collaborative documents and video. The choice for a firm whose threat model starts with email.
5. openDesk
The German public sector's sovereign suite, assembled from open-source components including Nextcloud, with office, mail, chat, video and projects, distributed through ZenDiS and partners. Built for ministries and municipalities, and our openDesk guide explains when a company should look at it too.
6. ONLYOFFICE Workspace and DocSpace
Document-first collaboration with a Microsoft-like editor, self-hosted or in ONLYOFFICE's cloud. Good where the work is documents; thinner on mail and video. Note that ONLYOFFICE suspended its Nextcloud partnership in 2026 over the Euro-Office fork, which matters if you planned to combine them.
7. Zimbra
A mail and calendar server with a long enterprise history, licensed per mailbox through partners and hosted yourself or by them. The answer when the only thing you want to replace is Exchange.
8. Self-hosted Nextcloud
Everything Nextcloud Hub offers, for the price of a server and an administrator's time. Our cost comparison prices the hours honestly: cheaper above 50 users with staff in place, more expensive below.
How to choose
| If your reason for leaving is | Look first at |
|---|---|
| Price per seat and add-on creep | Nextcloud Hub, Zoho Workplace |
| Where the data lives | Nextcloud Hub (you choose the region), Proton (Switzerland), openDesk (your own datacenter) |
| Email privacy above all | Proton for Business |
| A public body under sovereignty rules | openDesk, or a dedicated Nextcloud Enterprise instance |
| Only Exchange needs replacing | Zimbra, or Nextcloud Hub's included mailboxes |
| You want Google instead | Google Workspace |
| You have a Linux team and want control | Self-hosted Nextcloud |
