If you get a response which includes
Classification: Undeliverable (with a red square next to it) and Status code: MailboxDoesNotExist
then the mailbox has most likely been deleted. If you get a response which includes
Classification: Deliverable (with a green square next to it) and Status code: Success
then the mailbox has not been fully deleted yet.
If your mailbox has only just been deleted it may be possible to reactivate it for you to rescue information. Unfortunately, this seems to be at the discretion of the VM forum staff as to whether they offer that or not.
This topic may be helpful if you can gain access and just want to archive the mailbox
