How to crash an Exchange 2007 Server?

Hello everyone!!!

I had a problem on Friday this last week.  I was running MS Exchange 2007 Management console and I had opened one instance of the Exchange 2007 Powershell.

IT appeared the server was humming along without any problems, however we had mounted a database from the recovery storage group and we were trying to copy users mailboxes from the recovery storage database to the users main mail box in their own database.  I don't remember the command we were using to do this, but it was a powershell command.

I executed the command one time and it ran without a hitch.  So I ran the command again on another users mail box and while that was runniing, I opened another instance of the Powershell and I ran the command again for another user's mailbox . We were in a hurry and we needed to solve the mailbox problem fast so again, while the second instance of the Powershell was running, I opened a third instance of the Exchange 2007 Powershell on the server and ran the command.

So three users were being being moved from one database to another with three instances of Exchange Powershell being opened and while that was all happening, FIVE databases under the first storage group shut down (dismounted) and three of the five were dirty shut downs.  

Needless to say, we had a really hard time recovering from that and everyone is blaming me for causing the problem.  

My question is, is it really possible to make an Exchange 2007 Server crash doing what I did.  Are there any KB articals or anything else posted on the web warning someone not to do this?  

I am trying to cover my butt and show management that this could happen to anyone.
any help would be appreciated.

Thanks in advance...
