It appears a substantial data recovery process is underway and we may have access to exported PST files. Once they have gone through this process it appears I'll have access to those PST files through the backend on my side. I'll be monitoring closely for any notifications and let you know as soon as I have access to them so we can get them re-imported into your new exchange mailboxes.
A blurb from their update:
As this process continues to progress, we look forward to initiating data recovery for each customer by distributing PST files to them through their secure customer portal.
