Q. How can I use an OR logic statement to create a query-based Distribution Group (DG)?

Start the Microsoft Active Directory Service Interfaces (ADSI) Edit tool (Start, Run, adsiedit.msc).

Expand the domain container, then expand the actual domain (e.g. DC=savilltech, DC=com).

Select the container in which you created the query-based DG--for example, CN=Users.

In the right pane, double-click the name of your query-based DG--for example, CN=JusticeLeague, as the figure at Figure shows.

Scroll down to the msExchDynamicDLFilter attribute and double-click it.

You'll see the attribute value, which looks something like

(&(!cn=SystemMailbox{*})(&(&(&(& (mailnickname=*)(|(&(objectCategory=person)(objectClass=user)(!(homeMDB=*))(!(msExchHomeServerName=*)))(&(objectCategory=person)(objectClass=user)(|(homeMDB=*)(msExchHomeServerName=*)))(&(objectCategory=person)(objectClass=contact))(objectCategory=group)(objectCategory=publicFolder)(objectCategory=msExchDynamicDistributionList))))(objectCategory=user)(cn=C*)(cn=B*))))

Notice that our DG criteria--(cn=C*)(cn=B*)--appear at the end of the attribute. To make the query use OR logic for these values, thereby requiring only one of them to be true, insert a pipe character (|) and a space before the first criterion (cn=C*) and an additional right parenthesis after the last criterion (cn=B*). The modified DG criteria would look like this:

(|(cn=C*)(cn=B*)))))

Click OK.

Click OK in the main property dialog box and close ADSIEdit.
