You would only need such a rule if, as well as your main address, you have other email addresses, called aliases, that are being forwarded to your mailbox, and you want emails to these aliases to be automatically moved to a subfolder. This sounds like a trivial question as there is already a rule condition called \\"sent to people or public group\\" that you can choose when creating an Inbox Rule. The problem is that if you use this condition the rule becomes a \\"client only\\" rule which then only operates when you have Outlook open, instead of operating all the time, which is what you want. There must be a reason why Microsoft made rules that use this condition to be \\"client only\\" but I can't work it out. Anyway, the trick to get this rule to operate all the time is to select a different condition called \\"with specific words in the message header\\" and enter the alias address you want the rule to apply to as the words this rule uses. The message header of an email is the section that contains the To, From and Subject lines plus many more headers that are not displayed in Outlook but contain information about the email. It's possible this rule will trigger when it shouldn't if an email is sent to both your main email address as well as the alias or if the alias address happens to be in the Subject line, but this would be a rare occurance and would be a minor inconvenience.
