Detailed Description
noteNote:
When you use the Get-Mailbox cmdlet in on-premises Exchange environments to view the quota settings for a mailbox, you first need to check the value of the UseDatabaseQuotaDefaults property. The value True means per-mailbox quota settings are ignored, and you need to use the Get-MailboxDatabase cmdlet to see the actual values. If the UseDatabaseQuotaDefaults property is False, the per-mailbox quota settings are used, so what you see with the Get-Mailbox cmdlet are the actual quota values for the mailbox.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they’re not included in the permissions assigned to you. To see what permissions you need, see the “Recipient Provisioning Permissions” section in the Recipients Permissions topic.

Parameters

Using the IgnoreDefaultScope switch introduces the following restrictions:

When you use the ReadFromDomainController switch, multiple reads might be necessary to get the information. You don’t have to specify a value with this switch.

noteNote:
By default, the recipient scope is set to the domain that hosts your Exchange servers.
RecipientTypeDetails Optional Microsoft.Exchange.Data.Directory.Recipient.RecipientTypeDetails[] The RecipientTypeDetails parameter specifies the type of recipients returned. Recipient types are divided into recipient types and subtypes. Each recipient type contains all common properties for all subtypes. For example, the type UserMailbox represents a user account in Active Directory that has an associated mailbox. Because there are several mailbox types, each mailbox type is identified by the RecipientTypeDetails parameter.
