How can I see personal distribution lists from the Find Names Address book in OWA?

The Find Names address book dialog does not display Personal Distribution lists. (Refer to https://support.microsoft.com/kb/820280/en-us for details).

There is a third party add-on from Messageware (www.messageware.com) which gives users the ability to see personal and corporate distribution lists, Public Folder contact lists, as well as custom Exchange Address Lists.
