The CloudFax service allows you to send and receive faxes using your UW-Madison Office 365 email account. Learn more about the CloudFax service.
Learn how to use the CloudFax service below:
Important: Your account must be enabled for CloudFax before you can send a fax email.
Compose a new email message.
Select the From address: Your primary Office 365 account or the Office 365 service account associated with your fax number.
Enter the fax number in the To: field as an email address.
Important: Sending through CloudFax no longer includes the sending fax number since you are not sending via a physical fax machine. If you want to provide your fax number to the recipient, add that information to the body of your email message you are sending.
Attach the file to be faxed to your email.
Note: Do not digitally sign your fax email with your UW Digital ID. If you do, the fax will not successfully send and you may get an "Invalid attachment" error.
Check the inbox of the service account associated with your fax number (ex: email@example.com) for an email with an attached fax file. Please note, you will need access to the service account associated to the fax number to view incoming faxes.
View, save, print, or forward the fax to any email address.
If your department needs a new fax number, please submit your request here.
