Email selection
The valid email address list can be created from a completely different LDAP search. This may be especially useful in dealing with users who leave the organization.
For example, when a user leaves the organization, you are likely to disable their account immediately upon departure. If you use the default filter in the users synchronization, this removes the departed user from the cloud service (disabled accounts are not synchronized). You might, however, want to allow email messages to be received for a while after the employee’s departure, so the email synchronization might still include the employee’s address.
To include European email addresses from the above example and also include departed users in the valid address list, set the LDAP search base to the company domain, and set the search filter to:
(&(objectCategory=person)(objectclass=user)(memberOf=CN=All Europe,OU=Global,dc=company,dc=com)
