In-Depth Look at Microsoft Office 365 E-Fax Options

There are a bunch of ways people ask this:
  • “Does Microsoft 365 offer fax?”
  • “Can I fax from Microsoft?”
  • “Can I fax using Microsoft office?”
  • “Where can I find Office 365 e-fax?”

TLDR: Microsoft doesn’t have a native fax service. But according to the New York Times Wirecutter review, Documo is one of the top-rated cloud fax providers, and it works cleanly with Microsoft tools.

Can I Send a Fax for Free from Microsoft 365?

No, unfortunately, Microsoft does not provide a free fax service. While Microsoft Office and Office 365 itself don’t have built-in cloud fax capabilities, you can use third-party services like Documo to send faxes directly from your Office 365 or Microsoft account.

Documo gives you a free 14-day trial that allows you to test sending faxes, making it the best alternative for those looking for a cost-effective solution, especially if you want to test out a service with enterprise-level pricing and services.

With Documo, you can send a fax from Microsoft in just a few steps, combining the simplicity of email with the security and reliability of modern faxing technology.

Is Microsoft Office 365 HIPAA compliant?

That depends – but you can set it up to be.

By default, Office 365 doesn’t encrypt emails end-to-end, which HIPAA requires. But if you layer in services like Paubox or Virtru, you can get there.

And either way, if you’re sending faxes with Documo, you’re covered: Documo is HIPAA compliant on every plan, and they’ll send you a signed BAA automatically. That’s one less thing to worry about.

How to Send a Fax via Microsoft Outlook with Documo?

Sign up for a Documo account with the Microsoft Outlook 365 address you want to use for sending faxes.
