    • If you want to query Exchange mailbox, its attributes related info then you can use Exchange Powershell to query. Here's the documentation. In case if you want to add the folder level permissions for users in mailboxes then you can use Exchange Powershell and Add-MailboxFolderPermission
      cmdlet. Here's the documentation.
    • If you want to get the mailbox usage then you can Microsoft Graph API reports. Here's the documentation.
