Outlook Signature Hyperlink Integration

I already have a finished signature layout—logo in place, text styled, and everything sized correctly—but the website address and mobile number inside that design still need to behave like live links when viewed in Outlook for Office 365. Because both links sit on the company logo image, I need them embedded so a reader can tap the logo on desktop or mobile and be taken straight to the site, or, on a phone, launch the dialer with the number pre-filled.

All I am looking for is the corrected HTML or signature file, ready to import into Outlook’s signature manager, plus a quick note confirming any settings I should check so the links stay active across replies and forwards. If you have already handled image-based hyperlinks in modern Outlook, this should be a short, focused task and I’d like to wrap it up quickly.
