You may not see every contact in the widget because CloudSponge only displays contacts that pass through some simple email validation. This ensures that your application only gets a list of contacts with reasonable looking email addresses.

One common address that is filtered is the Exchange address. These addresses generally follow this format:

/o=ORGANIZATION_NAME/ou=organizational group/cd=RECIPIENTS/cn=username</code>

If you would like all the emails to appear in the widget, you can set an option to override the filtering of these emails. Specifying:

performEmailValidation: false

in the csPageOptions will display every contact with an email address, valid or not.
