Sorry to hear you're having trouble.
Just in case there's a bit of a missed step in there I'll go ahead and post the information on how to create the hyperlink for you.
- In Outlook go to File>Options
- Go to Mail and select Signatures
- In Signatures and Stationary select the signature you want to edit or create a new one
- In the editor select the text that you want turned into a hyperlink
- If the hyperlink icon cannot be located then try pressing CTRL+K to open the hyperlink dialog
- Type the URL you want to link to and click OK
- Save changes and close the dialog.
