Problem with duplicate emails in outlook 2013

Posted on 2015-01-28
Last Modified: 2015-03-25
So I have a computer setup with an Exchange account in Outlook. We have another computer setup with the same account except it is setup as a pop account. The reason we have it setup as pop is the second user computer is just monitoring incoming emails and wants to be able to read and delete the emails without it affecting the first user. Obviously the pop account is set to leave all messages on the server. The problem I am having is duplicate emails showing up in the pop account. It seems like whenever the computer setup as exchange opens outlook it causes the other computer setup as pop to download emails again. Shouldn't the computer setup as pop know which messages it has downloaded and not download it again ?

Do you have SP3 for Exchange 2010 installed? Your issue appears to be similar to the one outlined in this article:

The fix in that article states to install Update Rollup 4 for SP1 but if you're running SP2 or later then obviously the article doesn't apply in this situation.

If you are still on SP1 then I would strongly advise you upgrade to SP3 - it's a direct upgrade so you don't need to install SP2 first.

You got me excited that it might be that simple. I just checked though and we are completely up to date with exchange. We are at SP3 with Roll up 8 v2

I want to double confirm whether all account or some special user experience this question.
Please double check whether there are some duplicate message in OWA.

Please try to disable Leave a copy of messages on the server, then try to restart Outlook and enable it again for testing.
Additional, please try to double check inbox rule or run outlook with safe mode to prevent add-ins and virus.

Try recreating the Outlook profile on the computer using the Exchange account in Outlook as well. Seeing as you think the duplicate emails only appear to be downloaded when Outlook is opened on the Exchange machine then there might be something wrong with the Outlook profile itself.

Unfortunately changing settings to remove file from server is not an option as the user whose mailbox it is needs all the emails in their exchange account. Nothing was duplicating in the exchange outlook or OWA. It was just the second computer receiving a copy of all the emails using pop would get duplicates. My solution was a workaround. I created a dummy account in exchange and set the users mailbox to forward a copy of all email to this dummy account. On the 2nd computer I set it up to download from the dummy account and since it was just a copy of the emails I was able to set it to remove messages from the server.

I'm guessing recreating the Outlook profile didn't help? Either way, good job! Thanks for letting us know what you did to workaround the issue, it may help others who also run into this same problem.
