Scan to Email issues

Hi,

I recently upgraded to Windows 10 Pro x64, and I am no longer able to scan to my email using Toolbox. I am using Outlook with Office 365, our email is IMAP, and the printer is an imageCLASS D1320.

When I click scan, it initiates and scans fine, however when it attempts to open outlook I receive an error "Cannot start Microsoft Outlook, The command line arguement is not valid"

I've tried re-associating file types, reinstalling the printer, reinstalled Office etc...

Any ideas?
