I guess it needs some alternative method to change some fonts... SO far as I know only excel can be managed with intune (and onenote).
Open Word and start with a clean new document.
Hit CTRL-D to start the Font settings.
Set your Font of choice and hit “Set as Default”
“Save as” the document to Normal.dotm
--> Add this normal.dotm to a new folder
--> Create a Powershell script that finds the copies the file to users his “%appdata%\Microsoft\Templates\Normal.dotm"
Set the font in Outlook on a clean machine by going to Options -> Stationary and fonts… in Outlook. Close Outlook.
On this Machine, go to "HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\MailSettings".
Export by right click on the MailSettings folder.
Value name: “ComposeFontComplex”
Value name: “ComposeFontSimple”
Value name: “CReplyFontComplex”
Value name: “ReplyFontSimple”
Value name: “TextFontComplex”
Value name: “TextFontSimple”
--> Add this reg file to the same folder where the normal.dotm exists
--> Add a reg import / silent with the location of the reg file or change/add the register values with new-itemproperty
--> create a new win32app which has the dotm/reg file and the powershell script in it
Value name: Font
Value type: REG_SZ
Note: In Excel it is possible to set the font through a GPO: “\Microsoft Excel 2016\Excel Options\General\Font”
--> do the same as with the outlook key or create an administrative template in intune
