How to install your email signature in classic Outlook
Classic Outlook for Windows supports two installs. Pasting is fastest and works for most signatures. If paste loses any styling, use Download .htm on your personal link and place that file directly in Outlook's Signatures folder for an exact match, logo, spacing, and colors included.

Open the generatorCopy your signature
Open your personal signature link and click Copy signature.
Open Outlook's signature editor
In Outlook, go to File, Options, Mail, Signatures.
Paste into a new signature
Click New, name it, click into the edit box, and paste (Ctrl+V). Set it as default for New messages and Replies and forwards, then click OK. For most signatures, this is all you need.
If formatting looks off, switch to the .htm method
Classic Outlook renders signatures with Word's engine, which occasionally reflows spacing or drops a color on paste. Go back to your personal link and click Download .htm to save the exact file instead.
Create the signature file, then swap it
In File, Options, Mail, Signatures, click New and give it any name so Outlook creates the matching file structure, then close Outlook completely.
Replace the file
Open File Explorer to %appdata%\Microsoft\Signatures, find the .htm file with the name you just used, and replace its contents with the downloaded signature.htm, keeping the original filename.
Reopen Outlook
Your signature now matches the preview exactly. Confirm it is still set as default under File, Options, Mail, Signatures.
