How to activate internet faxing from Microsoft Office applications
Microsoft Office uses Outlook to send faxes directly from Word, Excel etc. For this feature to work correctly you must ensure that Outlook is correctly configured, i.e. the "From" email address associated with Outlook must be registered with InterFAX to ensure your faxes are sent successfully.
The activation procedure involves downloading a specially configured MS Windows registry file. Follow the instructions below to download the file and activate support for internet faxing from MS Office applications.
Note: You will need to run MS Office Activation on every computer from which you plan to send faxes using the MS Office Internet Fax feature.
For an introduction to our Office fax offering, see the Microsoft Office Fax solution page.
