Little Exchange Server Puzzles

It may not be a secret for anyone, but for me it was a discovery that in the Exchange domain you cannot create accounts with the names microsoft @ domain, internal @ domain and default @ domain. These addresses are reserved by the system for system shared folders. And these addresses are real and existing, but you cannot send a letter to them, an incoming arc comes. If anyone does not believe - check. And do not convince me that this is just a coincidence :)




Ps: by the way different things come

             The mail system could not deliver the message.  The reason for the failure was not specified.  Check the address and try again.
