Hello, daisuke1
In Exchange Online PowerShell, some multi-valued properties may be returned as serialized .NET collection types such as System.Collections.ArrayList.
In the Exchange Online environment, use the following command!
Get-DistributionGroup <Group Name>
-IncludeAcceptMessagesOnlyFromSendersOrMembersWithDisplayNames |
fl Name,AcceptMessagesOnlyFromSendersOrMembersWithDisplayNames
This parameter is available only in the cloud-based service.
