Set-DynamicDistributionGroup (ExchangePowerShell)

A dynamic distribution group queries mail-enabled objects and builds the group membership based on the results. The group membership is recalculated whenever an email message is sent to a group. You can use the Set-DynamicDistributionGroup cmdlet to overwrite existing settings or to add new settings. The Conditional parameters that are used with the IncludedRecipients parameter are subject to the following limitations: The EQV operator is used for every property value, as in "Department equals Sales". Wildcards and partial matches aren't supported. The OR operator is always used for multiple values of the same property, as in "Department equals Sales OR Marketing". The AND operator is always used for multiple properties, as in "Department equals Sales AND Company equals Contoso". To create flexible filters that use any available recipient property and that aren't subject to these limitations, you can use the RecipientFilter parameter to create a custom OPATH filter. You can't use this cmdlet to replace a precanned filter with a custom OPATH filter, or vice-versa. You can only modify the existing filter. You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
