For for those wondering what a dial tone database is take a look at this article:Recovering a Mailbox Database Using a Dial Tone Database in Exchange Server 2003.  As far as your question goes the dialtone database will not have any of the server based rules that the user created, folder permissions, end encryption keys for OST files.  You can use the dial tone database as production but you will have to use exmerge to bring the old mail in.

According to quantum mechanics, for multi-electron atoms, a single electron around the nuclei can be in the state of linear combination of different eigen energy states. In that case, even the energy of the electron is not one of the eigen energies.

In chemistry, we often say that an electron is in an orbital (such as 1s, 2s), another electron is in another orbital, etc. How does it make sense if an electron is in a linear combination state?
