Editing HTML CSS of an email signature

Hi there,

I need someone to edit the email signature html file (see .zip file).

The issues is this:

1. The html file works for some email providers (GMX email accounts) -> files have the name "ALREADY GOOD"
2. The html file has layout issues in the Outlook App (bright and dark) and in Outlook Desktop (dark)

Please only experts who knows how they can edit the file in a way that works for Outlook App and Desktop.

Thanks :-)!

Cheers
