Parse Subject Line using Connect to Outlook??-1517951673

Is it possible to parse out the subject line of an email using Connect to Outlook?  In other words, I have a monitored folder where Sales Orders are coming in and the Sales Order number is ALWAYS in the subject line, however, there is other information also, so I would like to parse out the subject line using RegEx to JUST capture the SO#...which is SO123456

If it is possible...where is it done?

Thanks!!

I'm doing this for a DocuWare Cloud customer using workflow manager.  I use C2O to capture the email subject line and workflow manager to parse it into the appropriate index fields.
