Every object has an attribute: ExchangeVersion, which is used to determine the minimum version of the management tools that can manage the object.
In Exchange 2010 SP1 server, the send connector object has the ExchangeVersion:8.0.535.0. Because the build 535 for Exchange 2007 was the original RTM release, so the send connector object can be managed by any tool with Exchange 2007 onward, e.g. Exchange 2007, Exchange 2007 SP1, Exchange 2007 SP3, Exchange 2010, Exchange 2010 SP1, etc. However, the administrator mailbox with ExchangeVersion(14.0.100.0) can only be managed by Exchange 2010 onward. Exchange 2007 tools cannot manage it.
In Exchange 2007 SP3 system, the Administrator mailbox has ExchangeVersion(8.0.535.0). The mailbox can be managed by Exchange 2007 tools onward.
