Sending fax email requests from Microsoft Outlook where one or more .doc(x) files are attached requires the installation of Microsoft Word on the GFI FaxMaker server that is capable to open and view the attached.doc(x) attachments.
After Microsoft Word is installed on the GFI FaxMaker server, login to the GFI FaxMaker machine using the service account of the GFI FaxMaker FaxServer service. Open Microsoft Word and disable any user prompts to ensure that the conversion process later on does not require user interactions.
To locate the service account for GFI FaxMaker FaxServer service, navigate to Start > run > services.msc; right click the GFI FaxMaker FaxServer service account and go to properties, then review the credentials specified under the Log On tab.
For other Microsoft Office file types such as xls(x) and ppt (x), etc. it is recommended to install the required program from Microsoft Office Product Suite (e.g. Microsoft Excel)..
