Anyone else with this issue and any answers to how it can be fixed? 

I have Microsoft Outlook for Mac 2011 - for some reason - some of my email addresses (i have 5) are (on their own) adding one or more of my other email addresses as secondary contacts within my outlook contacts..

So when i send from one email address it looks like it's coming from another since the contact now has 2 or 3 emails associated with it. I never actually built the original contact in outlook, so it's doing this on its own.  I have found a number of subjects about "suggested contacts" and it seems like this might be the issue.  I'm trying to figure out how to disable but heck if i can find where to go on my version of outlook.  Anyone else seen this type of issue? Thanks very much.
