Exchange 2013 2016 dynamic distribution group membership query

Query the dynamic distribution group members of Exchange 2013 and 2016 according to the method described on the official website, and sometimes the list of distribution group members cannot be obtained normally. The address of the official website is: https://technet.microsoft.com/zh-cn/library/bb232019(v=exchg.150)

If the filter criteria of the dynamic distribution group specify that the rule is to filter members by the recipient container (OU), then using the following command to get the dynamic distribution group members will get incorrect results and will get a list of all mailboxes.

$FTE = Get-DynamicDistributionGroup "Full Time Employees"

Get-Recipient-RecipientPreviewFilter $FTE.RecipientFilter

According to my own tests, I need to specify the parameter-OrganizationalUnit parameter when getting dynamic distribution group members so that I can get the correct members.

Get-Recipient-RecipientPreviewFilter (Get-DynamicDistributionGroup-Identity ceshigroup). LdapRecipientFilter-OrganizationalUnit (Get-DynamicDistributionGroup-Identity ceshigroup). RecipientContainer-ResultSize unlimited

Get-Recipient-RecipientPreviewFilter (Get-DynamicDistributionGroup-Identity ceshigroup). RecipientFilter-OrganizationalUnit (Get-DynamicDistributionGroup-Identity ceshigroup). RecipientContainer
