A few months ago I started getting duplicate emails in my inbox. I have several GoDaddy domains and all the incoming messages to all my domains are doing the same thing. All the settings in Outlook (2010) are set correctly. Has anyone had this same issue and what is the resolution?
I had this problem and it was caused by an update to Microsoft Office. All I had to do to correct the problem was install another more current update. I went to the Microsoft website, searched the knowledge base for "duplicate emails" and several explanations were given. The biggest pain was the removal of all of the duplicates. Did you login to your webmail and see if there were duplicates in your webmail inbox? If there are, then it is something other than the office update.
Hope this helps,
