eFax and Office 365 (Microsoft 365) Give You Options

With eFax, you have two easy methods for sending faxes through Office 365 (Microsoft 365): eFax Messenger or email. Getting started is easy—just sign up for an eFax account, then follow these steps to activate your eFax Messenger tool.

This fax software program is a free download that turns your personal computer into a powerful tool for your business. Whether you need to view and edit, highlight specific points or crop the page, sign the form or send the document to multiple recipients—the eFax Messenger desktop app puts it all at your fingertips without the need to scan or print your fax documents.

Once you’ve signed up for eFax, point your browser toward the eFax Messenger page to download eFax Messenger. It’s a free download, and you’ll find the system requirements and the instructions for downloading it to your PC on the download page.

eFax Messenger is all about making the faxing process simple and easily accessible while saving you time. With eFax Messenger, you don’t have to print or scan your faxes to view or annotate them. There’s no need to print or scan faxes when you need to sign and send them — with eFax Messenger, just sign them, then hit “send.” It really is that simple!

After you’ve downloaded and installed the eFax software, follow these steps to send your document via eFax Messenger.

  • Pull up your Office 365 (Microsoft 365) program and use it to open the document you want to fax.
  • Find the File menu and click on the Print selection. This will open a print dialogue box.
  • Look over the options in the Print dialogue box, and you’ll see you have the option of selecting a printer. You’ll need to choose eFax Messenger as your printer.
  • Almost done! Now you’ll click OK or Print, and the file you’re faxing should be displayed in the eFax Messenger window. You’re ready to send your fax.

For your fax to get where it needs to go, you’ll have to designate a recipient. There are two methods you can use to enter the recipient’s information:

  • Option one. Locate the To field. This is where you’ll manually enter your recipient’s fax number or enter multiple numbers if you have more than one recipient for your fax.
  • Option two. If you’ve populated your eFax Messenger Address Book, you can begin typing the name of your recipient and let your contact list display potential matches. Click on the one you’re sending your fax to, and their contact information should fill the recipient information slot in your eFax Messenger.

Once the recipient’s information is entered, you’re ready to move on to the next steps. Add a couple of words to give the fax a subject but keep it brief. Also, include an attention name to be sure the right person gets your message.

If you need a second page or more, adding a new page isn’t a problem. In fact, you have options to choose from when creating extra pages for your fax. You start adding pages by clicking on the Add New Page (or + sign) button in the sidebar. Your option choices will be listed and waiting for you to choose the type of page you want.

  • Need to add a blank page to your fax? Go with the Blank page option.
  • Do you need a pre-formatted cover page to accompany your fax? The Cover page option is your best choice.
  • Would an image or PDF file make the perfect fax page? The Import file option is the one you’ll want to select.

If the type of document you need to add doesn’t fit into any of the options you’ve been given, there’s a way to get the job done. Click on Attach File, then select the one you wish to add, and the program will upload it.

When you’ve compiled your fax the way you want it, click Send Fax, and your work is done.

These simple steps can be used to fax your documents from other programs included in the Office 365 (Microsoft 365) suite. Should you have a need to fax documents from Word, Excel, or PowerPoint, eFax Messenger has you covered. On those occasional times when you need to fax documents from other Windows programs, select the print to fax option with the eFax Messenger print driver, and you’re good to go!

If you’re using an Outlook email account and find you need to send a fax, eFax makes sending that fax as simple as a few clicks of your mouse, including the option to fax from Outlook.

Start by creating the email message you want to send. Once that’s done, you’ll need to enter the recipient’s fax number in the To field. Make sure the receiving number ends with @efaxsend.com. You’re essentially making the recipient’s phone number appear as an email address.

If you’re attempting to send a fax internationally, you’ll need to include the country code with the complete destination number. For example, if you’re sending to the international fax number +1 333 111 2222, you’ll enter it into your fax’s To field as [email protected].

If you want to add a cover page, prepare it for faxing by typing the text you want into the body of an email message or build a personalized cover page using a cover page template and adding your individualized text.

Got a small stack of documents that need to go to that international fax number? Not a problem. eFax lets you include up to ten additional files or documents.

When everything is as you want it, hit Send. eFax will take care of all the magic needed to convert your email message into a fax, then send it speeding on its way to your intended recipient.

It’s even easier to send emails with eFax messenger. First, download and install the eFax Messenger program, and log into your account.

Online Faxing Service vs. Traditional Faxing Hardware

Traditional faxing hardware has served its purpose for many years. But the benefits offered by online faxing services like eFax make it the perfect choice for the modern era and for those seeking an easy, cost-effective and efficient way to fax using their Office 365 (Microsoft 365) software suite.
