How to stop downloading unwanted emails from Aol in Outlook 2010

We have a very peculiar situation.  We started using Outlook 2010 and copied our PST from our old computer to the new computer and we open Outlook 2010, it starts downloading over 1,900 emails from the Aol server.  Yet in the old PC it doesn't do this.

Finally solved it.  Greatly appreciated all help and will award for such.  Nevertheless, this is what we did to solve the issue of downloading over 1,900 emails already download.

1, Opened up the Windows 7 PC with Outlook 2007 and download the days emails
2. With the Outlook opened, we opened up the web-mail of AOL
3. After verifying that all new emails have been download in the Windows 7 PC Outlook
    2007, proceed to delete all emails in the web-mail
4. Closed web-mail and Windows 7 Outlook 2007
5. Copied the PST of Outlook 2007 to Outlook 2010
6. No more problem of continuous emails downloading from email server (obviously since
    all emails was deleted from server)

Thanx all.

Will proceed close the question and award all EE participant and also include this entry for other members with similar problem.

In our PC we have Outlook 2007 and have it configure "not to delete emails from server".  This is so because we have iPhone and iPad sync with outlook emails.

Hope this helps.

It's already filtered.  To be more specific by "unwanted emails", is that the emails being downloaded has already been download in the old PC (the emails downloaded are dated from June 2010 up to present date).  It seems that when we copied the outlook 2007 PST to the new PC with outlook 2010, the new outlook detect that it hasn't download those emails.

We thought maybe the outlook 2010 "needed" to go thru that process of downloading those emails so we left overnight doing it (maybe the Outlook 2010 instance Has some sort of identifier or something that detected pending emails).  So it download all 1,900 emails.  Since outlook 2010 downloaded all we thought it did the process that needed, so we deleted and copied the old PST again but it started downloading again.

Hope this helps

Outlook duplicate records: Why they occur and prevention
rayluvsAuthor Commented:
Just read your link and the only thing we see that could be a solution (and logical) it's the section of "Reinstallation and re-configuration of Microsoft Outlook could also Outlook duplicate records".

The other areas can't be it because it is a new PC and the only thing we are ding is passing the PST.

We'll try and let you know.

Typo fix:  we meant outlook 2010 downloads emails since June 2012 not 2010.  That being said, what about creating a rule not to download emails since June 2012.  Is that a viable option?
rayluvsAuthor Commented:
Ok this is what we did, according to "Reinstallation and re-configuration of Microsoft Outlook could also Outlook duplicate records":

1. Delete the OL2007 PST in OL2010.
2. Start Outlook with a clean .pst (it asked for my old PST and cancelled it and created
    a new one).
3. OL2010 started downloading all emails messages.  Not only the ones of today,
    but all 1,900 since June 2012.

So even with a new PST, it starts the downloading again since June 2012.

Am I doing something wrong or am I missing something?
rayluvsAuthor Commented:
Also to test to assure a clean PST, I delete all contents of C:\Users\user\AppData\Roaming\Microsoft\Outlook.  Still when starting, it starts download all 1,900 emails.

One question:

can it be possible that the area where Outlook 2010 searches to see if it has PST assign to it, needs to be reset?  

What I mean is, when I delete the PST and start OL2010 it asks for the same PST I just delete.

Where can I delete that reference?

any suggestions?

We transfer a PST from a Outlook 2007 Windows 7 PC to a our new Outlook 2010 Windows 8 PC.

The problem faced is that when copied to Outlook 2010 Windows 8 PC, it start to download all emails since June 2012.

But when we go back to the to the Outlook 2007 Windows 7 PC , it doesn't do this.

Our outlook setting is for an AOL account and to leave a copy on the server (see pic below).  The purpose of setting "leave a copy on server" is because we use iPhones and iPads and always received emails on thos devices:
One thing we did, thinking that it may trick Windows 8 Outlook 2010 to think that it doesn't no longer need to download the emails from server since June 2012, was leaving the Outlook 2010 downloading all the emails.  Then deleting this PST and copying back the original Outlook 2007.  Same problem; starts to download since June 2013.

Based on this, we have noticed that there may be some sort of configuration in some temp location within the hard disk outlook area where it sends a signal to the AOL server to download since June 2013.  We say this because the iPhones or iPads doesn't reflect this behavior.

Can that configuration be access to "stop" signaling AOL server to stop download since June 2012?

What else can we do?

Thank you all.

Have a look into below post

Outlook is downloading thousands of old/duplicate emails from a year ago

don't quite understand, which is the one you are recommending?
rayluvsAuthor Commented:

Just noted that both iPhone and iPad lost all our emails; seems that the contents of these 2 devices are based on what is in the server, it doesn't save it to the devices.

If there some help, greatly appreciated.
