Formatting Issues with HubSpot Signature Generator in Outlook

Hi everybody – I am trying to help a client with their email signatures. They love the ones that HubSpot’s free generator makes, but for some reason, when I bring it into Outlook – it messes with the icons or the text color. I even tried to remove the hyperlinks in the signatue so it wouldn’t turn it link blue.

The only answer I’ve seen is that “outlook handles HTML differently” – but is there any way to get them set up with these signatures without having to manually alter every one of them?
