Management role scope filters can be used to define management scopes that are highly customizable. Using scope filters, you can create a scope that matches how you segment your recipients, databases, and servers so that administrators can manage only those objects they should have access to. Scope filters can use nearly any recipient, database, or server object property.
To use management role scope filters, you must be familiar with management role scopes. For more information about management role scopes, see Understanding Management Role Scopes.
Filtered custom scopes in Microsoft Exchange Server 2013 are created by using the New-ManagementScope cmdlet. The two types of filtered scopes, recipient and configuration (which consists of server and database scopes), are divided into regular scopes and exclusive scopes. The following list shows which parameter on the New-ManagementScope cmdlet to use to create each type of filtered scope:
- Recipient regular filtered scope To
create this type of filtered scope, use the
RecipientRestrictionFilter parameter.
- Recipient exclusive filtered scope To
create this type of filtered scope, use the
RecipientRestrictionFilter parameter along with the
Exclusive switch.
- Server-based configuration regular filtered
scope To create this type of filtered scope,
use the ServerRestrictionFilter parameter.
- Server-based configuration exclusive filtered
scope To create this type of filtered scope,
use the ServerRestrictionFilter parameter along with the
Exclusive switch.
- Database-based configuration regular filtered
scope To create this type of filtered scope,
use the DatabaseRestrictionFilter parameter.
- Database-based configuration exclusive filtered
scope To create this type of filtered scope,
use the DatabaseRestrictionFilter parameter along with the
Exclusive switch.
When you create a filtered custom scope, the scope attempts to match the filter with any objects accessible within the implicit read scope of the management role. If an object is found, it's included in the results returned by the filter, and the object is made available to the management role by the custom scope. A filter can't return results that are outside of the implicit read scope of the management role.
If you specify a recipient filter using the RecipientRestrictionFilter parameter, you can use the RecipientRoot parameter to specify an organizational unit (OU) to restrict the filter to. When you specify an OU in the RecipientRoot parameter, the recipient filter attempts to match recipients that reside in that OU only, rather than within the entire implicit read scope.
To create a management scope using the filterable properties included in this topic, see Create a Regular or Exclusive Scope.
Filter syntax
Both recipient and configuration filters use the same syntax to create a filter query. All filter queries must have, at minimum, the following components:
- Opening bracket The opening brace ({)
indicates the start of the filter query.
- Property to examine The property is the
value on an object that you want to test. For example, this can be
the city or department on a recipient object, an Active Directory
site name or server name on a server configuration object, or a
database name on a database configuration object.
- Comparison operator The comparison
operator directs how the query should evaluate the value that you
specify against the value that's stored in the property. For
example, comparison operators can be Eq, which means equal
to; Ne, which means not equal to; Like, which means
similar to, and so on. For a full list of operators that you can
use in the Exchange Management Shell, see Comparison
Operators.
- Value to compare The value you specify
in the filter query will be compared to the value that's stored in
the property you specified. The value you specify must be enclosed
in quotation marks ("). If you want to specify a partial string,
you can enclose the string you provide in wildcard characters (*)
and use a comparison operator that supports wildcard characters,
such as Like. Any string that contains the partial string
will match the filter query.
- Closing bracket The closing brace (})
indicates the end of the filter query.
The following components are optional and enable you to create more complex filter queries:
- Parentheses As in mathematics,
parentheses, ( ), in a filter query enable you to force the order
in which an operation occurs. Innermost parentheses are evaluated
first and the filter query works outward to the outermost
parentheses.
- Logical operators Logical operators tie
together one or more comparison operations and require the filter
query to evaluate the entire statement. For example, logical
operators include And, Or, and Not.
When put together, a simple query looks like {
City -Eq "Vancouver" }
. This filter matches any recipient
where the value in the property City equals the string
"Vancouver".
Another, more complex, query is { ((City -Eq
"Vancouver") -And (Department -Eq "Sales")) -Or (Title -Like
"*Manager*") }
. The filter query is evaluated in the
following order:
- The properties City and Department are evaluated.
Each is set to either
True
orFalse
, depending on the values stored in each property.
- The results of the City and Department statements
are then evaluated. If both are
True
, the entire And statement becomesTrue
. If one or both areFalse
, the entire And statement becomesFalse
. The following applies:
- If the And statement evaluates as
True
, the entire filter query becomesTrue
because the Or operator indicates that one side of the query, or the other, must beTrue
. The object is exposed to the role assignment.
- If the And statement is
False
, the filter query continues on to evaluate the Title property.
- If the And statement evaluates as
- The Title property is then evaluated. It's set to
True
orFalse
, depending on the value that's stored in the Title property. The following applies:
- If the Title property evaluates as
True
, the entire filter query becomesTrue
because the Or operator indicates that one side of the query, or the other, must beTrue
. The object is exposed to the role assignment.
- If the Title property evaluates as
False
, the entire filter query evaluates asFalse
, and the object isn't exposed to the role assignment.
- If the Title property evaluates as
The following table shows an example with values, which
indicates when the complex query would evaluate as
True
, and when it would evaluate as
False
.
Complex query
City | Department | Title | Result | ||
---|---|---|---|---|---|
Vancouver (True) |
Sales (True) |
CEO (False) |
True because both City and Department evaluated as True. Title isn't evaluated because the filter query conditions are already satisfied. |
||
Seattle (False) |
Sales (True) |
IT Manager (True) |
True because Title evaluated as True. The results of the City and Department comparison are discarded because Title evaluated as True, which satisfied the filter query conditions.
|
||
Vancouver (True) |
Marketing (False) |
Writer (False) |
False because City and Department didn't both evaluate as True, and Title also didn't evaluate as True. |
Filterable recipient properties
You can use almost any property on a recipient object when you create a recipient filter. For a list of filterable recipient properties, see Filterable Properties for the -RecipientFilter Parameter. Although this topic discusses the properties that can be used with the RecipientFilter parameter on other cmdlets, most of these properties also work with the RecipientRestrictionFilter parameter on the New-ManagementScope cmdlet.
Filterable server properties
You can use the following server properties when you create a management scope with the ServerRestrictionFilter parameter:
- CurrentServerRole
