Get mailbox recoverableitemsquota

To get the recoverable items quota for a mailbox in Exchange Online, you can use the following PowerShell command:

Get-Mailbox -Identity <mailboxName> | FL RecoverableItemsQuota

Replace <mailboxName> with the actual name of the mailbox you want to check.

Alternatively, you can use the following command to get the recoverable items quota for all mailboxes in the organization:

Get-Mailbox -ResultSize Unlimited | FL Name, RecoverableItemsQuota

This will return a list of all mailboxes in the organization, along with their recoverable items quota.

Note: The RecoverableItemsQuota property returns the quota in bytes. You can use the Get-Mailbox cmdlet with the -Property parameter to specify the unit of measurement, for example:

Get-Mailbox -Identity <mailboxName> | FL RecoverableItemsQuota -Property @{Name="RecoverableItemsQuota";Expression={$_.RecoverableItemsQuota / 1GB}}

This will return the recoverable items quota in gigabytes.
