How to see which accounts are excluded from Distribution Channels

Click 'Customers' on the top left, then 'Customers' on the blue menu bar.  Now click 'Exceptions/Exclusions' in the 'Customers' menu on the left hand side.

You will now see customers who registered to receive their invoices electronically, but have subsequently been excluded.  You will also see customers marked as excluded from a specific delivery channel. This list can be exported as an Excel-compatible file using the link underneath the search field.
