Intel employees' Outlook clients are configured to delete emails in the "sent" folder after one week. It would surprise me if there were any automatic indexing or central archiving going on - the cost would be huge. So, if you want to get back any of these emails, you need to a) find a backup tape from the week between sending and automatic deletion, then b) identify and restore the respective outlook .pst file and c) find the respective email.

Now, if you want to serve the AMD case, please repeat this procedure several thousand times. For any given number of employees and sites, that is.

While it is technically not an issue to follow the above steps, I can easily understand why Intel has an issue serving the court's orders here: they would have to allocate an army of IT people to browse tapes, folders and files. 
And then, let's not forget that most of these emails would just yield gibberish anyway ;-)

Let me get this straight...... the largest and what some call the most successful technology company not able to keep important emails? Aren't they also consulting IT directors how to do managability and security?

There must be something in those emails that Intel doesn't want anyone to see. Maybe the fact that whenever AMD has a good product, it threatens its customers and channels not to go with the superior AMD product? Maybe if AMD were allowed to make some money when they have a superior product, they would have more money to invest in engineering so they wouldn't have issues like Barcelona.

Intel is so busted.

Well done Chuck. You have really helped your case here. Now we know it's not lost, you just don't know where it is.
