Outlook 2003 on Windows XP retrieves duplicate emails?

every time i've had a user complain about this particular problem i've traced it to the 'schedule an automatic send/recieve every x minutes' setting. if this is set too low, then the outlook client is still downloading mail when it send/recieves again duplicating mail over and over again. this is especially a problem over slow connections or if you have lots or emails, large attachments, etc. increase your send/receive time and see if the problem goes away.

I've had this KIND of thing happen, but I have a strong feeling that we're short of some info here. Are ONLY the spam messages duplicated? Are they all 'To' one particular account?

In my case, I found that two different e-mail accounts had been set to download mail and each was pointed at the same 'catch-all' account. On another occasion, I found that I had accidentally left a forwarder set to push mail from one account to a second and they were both receiving the same e-mail, so I got dupes.

I have had this happen with Outlook 2003 and suspected either AVG and/or Spamfighter, where users leave a copy of the message on the server.
I think when the free version(s) of AVG and Spamfighter leave their tag at the bottom of the message, it changes the email enough that the server thinks it's a new message and posts it over and over.
My suspicions are due to the fact that the duplicate messages have additional tag lines at the bottom of the message.
Although the issue may have been fixed in more recent updates (this was happening to me about a year ago) I simply moved everyone to Outlook Express which wasn't affected by the anomaly.

Hi all,
my company has encountered this problem these couple of days. Where users receive duplicate emails (about 30 same emails).

Our exchange server 2003 is installed in our Win 2000 Server.

I have been surfing around the net to find a solution for this; but unable to.

If anyone has run into this problem before and able to solve, please help. Thank you.

Hi !

I also have the same problem..but in my case I susepct it is something to do with the Rules I have setup. If a message satisfies two or more rules, it will be - in my case - sent to the two/more folders . UNless I somehow set rules up so that the message satisfies only one rule at a time ...

Hope this made sense to some here !

Outlook will drop the connection if it encounteres a mangled mime attachment, like a base64 encoded mime with a 0x10 CR character somewhere in it. Because it doesn't delete the messages from the server until the end of the transaction (which is typically broken MS logic), emails prior to the illegal message will be redelivered.

if you continue to have this problem and the KB article doesn't help, check the message on the server side with a hex editor or other control-code aware viewer, and manually delete the message from the server if you're unable to apply a filter for it.

We're experiencing a similar situation, but definitely without another app. checking messages, and without Exchange. Our site is hosted on XO.COM.
The check e-mail time is set to 3 minutes, which may have been shorter than needed once an employee got back from a one-week trip. All e-mails were being left on the server. Outlook 2003 (on XP Pro) was set to not leave copies. Every time it checked, it brought in another copy of every message, not just junk. We deleted and reinstalled the account twice.
One tech rep at XO, as soon as I started to describe the symptoms, asked if I was running Outlook 2003; he's seen it a few times, but didn't have a fix for it.
I hope soon to try one thing that may work, but would appreciate any ideas.
Thanks in advance!

I am experiencing the same problem were I work. The only thing is only one user is experiencing this problem and not the rest, who seem to be all happy with the new company email server.

I am still doing some research and testing and will post my solutions this afternoo.

I have a bigger problem.

I usually use two ISPs. One is at home and the other is in my office. The problem is that when I download emails in my office after dowloading them at home, they are all downloaded over and over.

I am using outlook 2003 and using mail service of the business Yahoo! Mail.

I have also updated my outlook to SP2 as Microsoft recommend.

Does anyone have the same as mine? Please give me your advice.

Many thanks!

Hi I have a problem. I get a duplicate mail with only one person. I am looking Outlook 2003 set up in POP. What could be the reason for this? I kept getting only a single message per each single message coming from a certain sender. This is really annoying. Can you give me some advice if what could be the reason for this?

I had the same problem with Outlook and Exchange server: only one person was getting thousands of duplicate emails each time he clicked on the send/receive button. This started to happen when we change from our external ISP POP3 mailbox to the internal MS Exchange server.

I thought the problem was on the server side, maybe a forgotten forward or something.

Actually, it was with the Outlook configuration. His config was accessing both the internal Exchange server and the POP3, making weird things happening.

Solution: delete the POP3 access from Outlook! As simple as...

I found that I had duplicate rules so outlook created duplicate emails to fill the rules.

One of my coworkers uses Outlook 2003. We all get email pop3 from the same email address and leave messages on the server. On my computer I am using the 2007 Beta Outlook. My outlook downloads the emails just fine but my coworkers commonly (about twice a week) gets stuck on a certain message and then stops downloading. It then starts downloading all the messages again from the begining. Two other computers are using Outlook 2003 also on the same mail account but have no problems.

The only way I can solve the issue is by going into webmail and deleting the bad message. It is time consuming and I would like to know how to make it stop. Thankyou

Hi,

I figured that Duplicate E-mail issue was due to wrong "rules" set by me. The "Rules and alerts" system is not intelligent to tell me if I have already added a user.

I am having trouble trying to save a copy of my email messages on my server. I use Microsoft Outlook 2003 with Microsoft Exchange and this option in the tools, accounts, and advanced tab does not offer me the choice to save a copy of my mail on the server. Is there a way I can save messages on my server to view while away from work?

simple soluction...

stop using outlook and exchange!! :)

please note that i'm a linux user running sylpheed and evolutin on a exchange company and we plan to replace the exchange for scalix... so i think its a valid solution, Outlook and exchange are too broke to solve

higuita: Get yourself a dictionary and try again.

Check the email accounts. If you are getting errors on the exchange server for a particular email address, look for other addresses within that person's profile. I had the duplicate problem stemming from a POP3 error. Deleted the pop3 email address but kept the user's main address- Problem solved!

First off, go to the regsitry, regedit32

1. Click Start, and then click Run.
2. In the Open box, type regedit, and then click OK.
3. Locate, and then click the following registry entry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\POP3Svc\Parameters\CheckPop3Tail
Note If the CheckPop3Tail registry value is not present, create it. To do so: a. Locate, and then click the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\POP3Svc\Parameters
b. On the Edit menu, point to New, and then click DWORD Value.
c. Type CheckPop3Tail, and then press ENTER.

4. On the Edit menu, click Modify.
5. In the Value data box, type 1, and then click OK.
6. Quit Registry Editor.

If that doesnt work, just delete the users mail box and recreate it. These are both known issues with microsoft

Dave,

I have a Windows XP machine in our office running Outlook 2003. My problem is that Outlook continuously retrieves duplicate, triplicate, etc spam emails from our Exchange server. I have tried every adjustment to settings possible but cannot stop this action. I have tried MS updates to no avail. Do you have any solution to this problem??

In our office users receive duplicate emails (about 30 same emails).

I'm having the same problem with my Mac. I'm running Mac OS X Leopard and am using Entourage 2004 for my mail.

A few weeks ago, it started downloading multiple copies of each e-mail. The first time I open my mail, it downloads one copy. Then as time goes on, it downloads another copy, then another. Sometimes as many as 30+ depending on how long I'm online. When I shut down my computer and restart, it stops downloading those messages and downloads multiples of the next set of messages.

Another problem I'm having is that I can't delete them. I tried and now I have multiples not only in my inbox but in my deleted items as well.

I didn't change anything with my settings; everything looks ok. I even deleted the messages off the server.

Does anyone know what's going on here?

I have one employee who gets duplicate emails only from our fax machine. Our fax receives and then forwards to a specific address. When the employee gets the fax she always gets it twice. Same thing if we scan something with the fax machine to her. But, if we change the forwarding address for the faxes to any other address it is only gotten once. Any Ideas?

Hi,

I just recently got exchange 2007 set up. The issue is that two emails show up in Outlook for each one received. I don't have a POP3 account involved. One email is looks "right". The other has several things converted to a hyperlink and the actual message that looks right is separated into an attachment. Any idea what the bad setting might be?

Thanks,

Tom
