UITS will begin migrating all Exchange mailboxes to the new 2013 server environment in the next few days. So, what does this mean for you?
* Virtually unlimited quotas (initial quota of 50GB will increase automatically)
* New Outlook web app
* New widgets in the Outlook desktop client and web app
* Better integration with Lync
If you’re logged in while your mailbox is being moved, you’ll get a prompt to restart Outlook.
