Microsoft Exchange: directory filter
This field is not in the Exonar web application. Our Support team can help you to set this correctly.
The filter is an LDAP query used in conjunction with a complete Exchange server crawl (when you do not specify a specific mailbox in the target).
It is used to target the Exonar Exchange crawl at a specific set of users in Active Directory.
For example:
(&(objectClass=organizationalPerson)(mail=*)(|(!(msexchhidefromaddresslists=*))(msexchhidefromaddresslists=FALSE)))
