We use Outlook 2010 / 2013. We have two exchange accounts. One local (domain) and one Office 365.
If we send internal mail, fonts are 100%.
If we reply to an external email sometimes it is 100% but other times our font has been changed to Times Roman.
All obvious settings have been looked at, in Outlook, Internet options, the defaults templates for email (.dotm) etc.
I am looking for a global solution and not one that involves changes to each machine on the network.
Any help will be greatly appreciated.
