By modifying the LDAP search filter it is possible to prevent the upload of addresses from users or contacts in Active Directory for which 'Hide from Exchange address lists' is selected.

To accomplish this, a filter can be added which excludes objects with the attribute msExchHideFromAddressLists set to TRUE.

In the synchronization tool open the configuration and click on 'Modify'.

Click on 'LDAP Search' in the wizard dialog.

The Search filter should already be enclosed in parentheses. If not, append ( to the beginning and ) to the end. Do not include any spaces.

Insert

(&(!(msExchHideFromAddressLists=TRUE))

at the beginning of the existing search filter

and append

)

to the end. Do not include any spaces.

Click 'Save'.
