Configuring preferences and options in Outlook.com
Hi
Outlook.com doesn’t support using a PDF directly as an email signature. A formatted signature with editable text and individually linked icons would suit what you need.
Try creating it in Word:
type your details, insert each icon separately, then right-click each icon and choose Link to add its website address. Copy the completed signature into Outlook.com under Settings > Accounts > Signatures > Add signature, then save. Send yourself a test email to check the formatting and links.
You can update the saved signature whenever needed without
