Exchange restore from last nights backup

The RAID card in our server took an unfortunate turn this afternoon and we are in the process of using and acronis image and mounting the backup in a Hyper-V environment.  The question that we have is since the backup was performed last night and end user had email sent to their outlook client throughout the day, willl their outlook clients delete the cached email from today when they connect to the restored virtual instance running the previous nights image and those emails are not on the exchange server?

Yes - the cached Outlook client will never override the mail server. The latest mail will be lost during sync.
Best option is to open the Outlook client (off-line) and export the content to a PST. This can be imported after the restored server is back on-line.

"Conflict handling steps apply to both Office Outlook 2003 Service Pack 3 and Office Outlook 2007 Service Pack 1 working with either Exchange Server 2003 Service Pack 2 or Microsoft Exchange Server 2007 Service Pack 1 — when the Office Outlook 2007 or the Office Outlook 2003 client is configured to work in Cached Exchange Mode."

See 'Scenario 2 - A new item is in the cache on the client computer, and does not exist on the Exchange Server computer. No conflict.'
"No conflict, because we only have a new item on client...Upload new item to Exchange."

Is this correct?

Correct - it should work.
But my suggestion did not specify any version of client - this was suitable for any Outlook capable of runnning cached mode.

I would be interested to hear if it works as well as it is meant to - backing up the content by exporting to PST is to safeguard the user data.
