I am trying to set the default font in Outlook 2013 as per the customer's request and am having no success.
First I create a NormalEmail.dotm file and added it to the Office Customization Tool, created an msp and added it to my package. After installing Office 2013 I check and the NormalEmail.dotm is on the machine in %appdata%\Microsoft\Templates folder waiting to be loaded. When launching Outlook 2013 on first run it renames my NormalEmail.dotm to NormalEmail15Pre.dotm. I created the file in Word 2013 so it's not a 2010 version and it (NormalEmail15Pre.dotm) open cleanly in Word 2013 (it does not open in compatibility mode). If I close Outlook and rename NormalEmail15Pre.dotm back to NormalEmail.dotm Outlook opens and uses my template without any issue. This is not a solution as I have 1000's of deployments and can't do this manually. One other thing, I did have this same problem with the default font in Word 2013 but by implementing a registry setting (HKCU\Software\Microsoft\Office\15.0\Word\Options\MigrateNotmalOnFirstBoot = 1) it used my Normal.dotm template on first run, if such a setting exists for Outlook I can't find it.
Also I did try to set the font through the mailsettings (HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\MailSettings) in the registry as we did with O2007 and O2010 but those do not load into Outlook when tweaked. http://blogs.technet.com/b/odsupport/archive/2009/04/24/how-to-deploy-specific-fonts-in-office-2007.aspx
Thank you for your help.
