Microsoft 365 fax: what is built in and what is not
Microsoft 365 has no built-in fax capability. Outlook cannot dial a fax machine, Word has no send-as-fax option, and nothing in the admin center turns email into fax. Faxing from a Microsoft 365 setup always involves something extra: a legacy Windows tool, an enterprise connector, or an online fax service. This fax-from-computer.com guide sorts those three paths by effort and cost, so you can get a document from Office to a fax machine without buying hardware.
Get Started NowIs there an O365 fax feature? The short answer
No version of Office or Microsoft 365, personal or enterprise, includes faxing. The confusion usually comes from two places: Windows itself ships a fax tool, and Microsoft's marketplace lists third-party fax connectors. Neither is part of your subscription. Outlook on its own can only send email, and a fax machine is not an email recipient.
The Windows 10 fax program: Fax and Scan
Windows 10 and 11 still include Windows Fax and Scan, the holdover people often mean by MS fax. It genuinely sends faxes, but only through a fax modem installed in or attached to your PC and connected to an analog phone line.
Few modern computers have a modem and few homes keep a landline, so for most people Fax and Scan is a dead feature. If you do have both pieces, it handles basic sending, but you get no encrypted storage and only a local log as proof of transmission.
Enterprise fax connectors
Larger organizations sometimes bolt faxing onto Microsoft 365 with third-party cloud fax connectors that route documents through Exchange or Teams. These are real products aimed at IT departments: they involve per-user licensing, admin configuration and vendor contracts, and they make sense when a whole department sends faxes all day. For a small office or an individual who faxes a few times a month, they are overkill in both setup effort and cost.
The simplest path: fax from the browser
For everyone who does not run an IT department, the quickest route from a 365 document to a fax machine is the browser. Office already exports clean PDFs, which is the only preparation an online fax needs.
- In Word, Excel or Outlook, export or save the document as a PDF.
- Go to FaxToFax.com, sign up with your email and a one-time code, and choose a local or toll-free fax number.
- Upload the PDF, or attach a JPG or PNG, and enter the recipient's fax number.
- Send, then confirm the Delivered status and keep the time-stamped delivery receipt.
- Schedule the fax up to 90 days ahead if it needs to arrive on a specific date.
Choosing between the three paths
The right option depends on volume and compliance needs more than on technology. At fax-from-computer.com, this is the comparison we give readers who ask.
- Windows Fax and Scan: only sensible if you already own a fax modem and keep a landline.
- Enterprise connectors: justified at departmental volume with IT staff to run them.
- Browser faxing: no install, works on any computer including Macs, with delivery receipts and an encrypted inbox for received faxes.
- If you handle patient or financial records, look for encryption in transit and at rest and a BAA option; FaxToFax.com offers a BAA on its Business plan.
Microsoft 365 Fax: What Office Can and Cannot Do: questions
Does Microsoft 365 include a fax service?
No. No Microsoft 365 plan includes faxing, and Outlook cannot send to a fax machine. You need either a fax modem with a phone line, a third-party enterprise connector, or an online fax service in your browser.
Can Outlook send a fax?
Not by itself. Outlook sends email, and a fax machine cannot receive email. Some third-party services bridge the two for enterprises, but the more direct route is uploading your document to a browser fax service and sending it from there.
What is the Windows 10 fax program?
Windows Fax and Scan, which is included with Windows 10 and 11. It sends faxes through a fax modem attached to your PC over an analog phone line; without that hardware it cannot send anything.
Is there an MS fax app for Microsoft 365?
Microsoft does not make one. The marketplace lists third-party fax connectors aimed at enterprises, while individuals and small offices usually find a browser fax service faster and far cheaper to set up.
How do I fax a Word document?
Save it as a PDF, upload it to FaxToFax.com in your browser, enter the recipient's fax number and press send. The status shows Delivered, In progress or Failed, and every delivered fax includes a time-stamped receipt.
