The Outlook signature Amicus is using is incorrect\not there
Amicus uses your default Outlook signature. When you create an email from within Amicus it loads an Outlook email and should populate with your default email signature. This applies to the Outlook or the Exchange email link.
Make sure Outlook has a default signature:
Select New Email
Select Signatures from the drop down menu
Make sure that you have specified a default signature on the left side and on the right side make sure that signature is set under New messages and Replies/forwards.
Refresh the Outlook signature from within Amicus.
Select the Amicus Communications tab
Go to Actions – Outlook Email – Set Outlook Signature
Create a new email from Outlook and it will pull the default Outlook signature
