An Exchange mailbox may have multiple SMTP addresses assosiated with it. For example, John Doe has a mailbox with a primary SMTP address of and secondary SMTP address of As Outlook always resolves both SMTP addresses to a mailbox name, there is no way to see what address the message was originally sent to. The only known workaround is looking through message envelope headers (open a message > View > Options...).
Let's suppose John Doe would like to set a rule to put any emails sent to to a separate "JohnD-Inbox" folder. When he tries to set the rule, it does not work because of address resolving.

WhichAddress for Exchange® 2010 application allows user to see which address the message was originally sent to and set up a rule to separate the messages being sent to different SMTP addresses.
