Same operating system and email client but email renders differently
Myself and a colleague are both on Windows 10 with Outlook 2016.
When I view the email, it looks perfect. I have tested this on Litmus and it looks fine in all email clients. However, when she views it in her email it all looks completely wrong.
Has anyone had any experience with this and know how it can be fixed/troubleshooted? Or perhaps it's some sort of setting on her Outlook app?
