Exchange user with two mail addresses - using rule to separate mail
I have an exchange user that has an e-mail address firstname.lastname@example.org and also email@example.com. This is configured in the e-mail address tab in exchange management console > recipient configuration > mailbox > user properties.
Anyway, I'm trying to user a rule in outlook to put mail to firstname.lastname@example.org into a certain folder. I tried using a rule that looks for "specific words in the recipient address". When I configured it Outlook told me it would be a client only rule. However the rule failed to work properly. Mail was not moved into the folder.
I can see that in the headers of the mail message it shows email@example.com.
Can anyone tell me how this is to be accomplished properly?
