Hi I have Outlook 2010 configured with multiple accounts. But all my gmail accounts are sending two copies for one email. All of them are IMAP. I went through this article - http://social.technet.microsoft.com/Forums/en/outlook/thread/bc6defe9-cdd4-4ff8-910c-93793c796100 and it does not seem relevant to me. I have no extra rules. Also interesting thing is this is not happening with either hotmail account or with another POP account. 

Any clues on what's going on? 

Hi,

The most possible reason which might cause Outlook to send duplicate e-mails, is that your antivirus suite is configured to check every e-mail that is sent from your mailbox.

This will cause Outlook’s sending process to be interrupted in between.

Thus, it will resend the mail after it has passed virus screening – resulting in a duplicate copy of the same mail being sent.

So, I suggest temporarily disable the antivirus programs on your computer and check the results again.

You can also send to other recipients, such as yourself to test the results.

Also, check the Task Manager to see if there are two outlook processes running, as this could also cause duplication of messages

Hope it helps.

Best Regards,

Harry Yuan

Hi Harry,

Thanks for the suggestions but I do not have anti-virus software or two outlook programs.

Hi,

You do not need two Outlook programs. Just in Outlook, send an email to yourself and test the results

I had a similar problem but outloook 2010 wasn't actually sending duplicate emails just making two copies in the sent emails folder.

If this is the problem, I found the solution to this is in outlook 2010.

Go to

FILE / Info

Account Settings

EMAIL tab

double click the first email account you are getting duplicate sent emails

Click on the "more settings" button in the bottom right corner of the window

go to the "sent items" tab

click on the circle at the bottom " save sent items in sent folder on this computer"

click "OK"

"next" and outlook should automatically send a test message so you can see if the problem is fixed.

Thank you very much!  That worked beautifully and it appears that there are no longer duplicates of sent emails in my Sent box!

What this does is move one of the copies from your Gmail Sent box to your Outlook Data File Sent box.  So now you have one copy of a sent email in each location.  Not a big deal unless you are sending other emails out too.  Then the Outlook Data File Sent box becomes cluttered with everything you send out using Outlook.

Fixed the problem!  Thanks!

Excellent advice, Simon. It worked first time.

Thanks

It's there in Outlook 2010, click more settings, then click sent items, then check the circle at the bottom of the window.

I almost missed it too!

I have exactly Simon-San's problem, and I have Outlook 2010, but when I follow his solution instructions and get to clicking on "more settings", there's no "sent items" tab (just "General", "Advanced", "Security" and "Connection" tabs).  Is there any alternative way to get to the solution you've described?

Do you have more than one email account? This only affects email accounts that are hosted by Google. These won't always be "@gmail.com" email accounts. Google handles emails for lots of other domains too (like numail.org, etc).

Furthermore, it only affects you if you use IMAP protocol instead of POP protocol to access your Google-hosted mail account.

Unlike most mail systems, Google's SMTP (outgoing mail) server keeps a copy of every sent message and puts it into the "Sent Mail" folder on the server containing your messages. It does this because their web interface (gmail.com) is built around conversation threads that show both sides of the conversation. Outlook incorrectly assumes that it needs to put a message into "Sent Mail" (but Google's system already does this). You end-up with each sent message appearing twice in the Sent Mail folder.

It's usually not a problem, but it can be annoying and it means that Outlook uploads twice as much data as necessary.

Tekaverse was having the same issue and I just replied to him. Read that reply and see if it helps you.

If you have more than one email account in Outlook, I don't think you're looking at the right one.

Thanks.

Saved me some aggravation too.

This is a solution that works!

Finally.

Thank you so much.

This fixed my irritation I had been facing on Outlook.

My copy of outlook 2010 has no sent tab, and I had the problem with IMAP Gmail. The following text is from another group. The problem is with sync.

  When sending an email, a copy is placed in Sent folder of webmail. If Outlook also puts a copy in Sent folder in IMAP, there will be a duplicate copy. Turn off saving a copy in Outlook.

Worked for me. Turn off save copy of sent emails, and you will get one saved copy, not two. 

Hi,

I send you an orthodox solution and an explanation .

The orthodox solution is:

Go to File-> Account Settings-> Account Settings-> select your Gmail account-> button Change-> button More Settings-> tab Sent Items-> mark option: Do not save copies of sent items

The explanation is:

This happens because your are sending via the SMTP server of Gmail and have Outlook configured to safe a copy of each Sent Item. As all the messages that you sent via the Gmail SMTP server also stores a copy in your Sent Items folder of the Gmail account, youll end up with duplicates.

The solution isn't mine (I'd liket to!), you can check the original post on http://www.msoutlook.info/question/526.

Cheers!
