I have a client I am working with who has the Windows 7 black and white emojis showing up instead of the colour emojis you'd normally expect to display. The client has no problem in Gmail using the same web browser. Both Firefox 64 and IE 11.0.9866.19230 that they have on their computer seem to have the same problem on the Outlook site. Her emojis still show up in colour fine for others who she sends messages to, just not for her.
Is this a Outlook issue, or is there something wrong on the Windows 7 machine that they can do to fix things?
I've already had them clear their cache/cookies on their browser.
