The lasted update from the data center was not informative on status, just they continue to work on it and a lot on how to move your mail to another platform to get you up and running. I did that over the weekend with your temporary mailboxes and webmail.
Speaking of which, if you have been using Outlook on your desktop, you can export your mail, contacts and calendar into webmail so you have continuity of usage in webmail. I have done that with my own webmail.
All that said, I am in their call back queue as of this post. The call back queue is currently running 2-3 hours. When they call, I will answer. I'll post an update once I have one. Again, I believe this will last all week long. I will be surprised if sooner and extremely disappointed if it last longer.
