Your Signature Doesn't Appear when You Send Files
When you send files with FileCenter's "Send" button and Outlook, your default signature isn't automatically inserted in the message.
This is an issue that has plagued Outlook users for years. It actually has nothing to do with FileCenter. Rather, it happens any time an e-mail is initiated outside of Outlook. You'll see the same thing happen if you right-click on a file in Windows Explorer and select "Send To" > "Mail Recipient".
The bad news is that in all of these years, Microsoft has never addressed the issue. It gets passed along from one version of Outlook to another.
The only solution anyone has found is to use the "Insert" menu > "Signature" in the message composition window. However, to make matters worse, sometimes this menu isn't available either. But at least there's a solution for that: in Outlook, go to the "Tools" menu > "Options" > "Mail Format", and deselect "Use Microsoft Office Word to Edit Email Messages".
