Change the default font in word and outlook using intune

Microsoft templates like Normal.dotm do not directly refer to Calibri. Instead, they refer to the major and minor theme fonts. So instead of trying to replace Normal.dotm, replace the font theme that is attached to Normal.dotm.

@Paul McGeady, Thanks for posting in Q&A. In the command, I notice there's some environment variables which may be different when the command is running with different credentials. I guess the issue can be with the user we run the command.

Please check what we set for "Install behavior". If we set it to System, then the file maybe under system account. if we set it to User, then the file will be copied to the logging user when apply the app.

Good evening,

To change the default font in Word, i have written a remediation script to be used in Intune that adjusts and saves the 'Normal' style.

The script first checks if Word is installed.
Then it checks the OS language (in my case, I had to change the style from 'Normal' to 'Standaard' because we use a Dutch OS).
Next, it checks if Word is running; if not, the font is adjusted.
If Word is running, the script stops. However, with Proactive Remediation, you can schedule it to run every X days or every X hours if you want.

If you want to use the scripts, please make sure they run using the logged-on credentials!

You can adjust more styles; for this, you need to find the relevant styles first.
I have also included a script for this.

Hopefully, this will be useful to you!
