Outlook 2010 Duplicate Attachments w/IMAPI Servers RRS feed

  • Question

  • Using: Outlook 2010 (Issue ONLY occured since upgrading from 2007)

    Issue: When receiving emails from IMAPI configured servers (like Gmail) all attachments show 2x. Only 1 is valid but still they show twice.

    Does anyone know what the resolution is to this issue?

    It does not appear to be happening with POP received attachments.

    Thank you in advance for your assistance.

  • what content filtering are you using? try switching it off just to test and see what happens.

  • Hi,

    Do you use antivirus program to scan incoming email? If so, try to disable it to have a try.

  • I have had this issue for a while with Outlook 2010connected to an IMAP account ... I have switched off email virus scanning and content filtering and still get the same problem.


    If I check the email using web-mail then it only has one attachment on the IMAP server but when it arrives in outlook in has mutliple copies. Sometimes it contains one duplicate other times it is more than one (may be related to the number of people copied on the email?).

    Additionally , lets say the attachment is 1Mb then Outlook reports the size as 1MB but the email appears to contain 2 or 3 attachments each 1Mb in size.


    Several colleagues I have spoken with also share this issue.

  • WebSight, did you find a solution to your question? I currently have the same issue with a gmail account.

  • I did not find a specific solution although the problem now seems to have gone away in the last 2-3weeks. I'm not sure why this is. I have implemented a couple of Microsoft updates and also updated my Norton Antivirus to the latest 2011 version.

  • I am also suffering this situation after I upgraded from 2007. Sometimes, it got even worse, the email subject and email body are mismatched, after I reboot outlook itself, it got matched again.

    What's matter with my outlook 2010, should I remove it and reinstall?

  • Also having the same problem.  Using MSE for virus protection. Is there a setting I need to change there?

  • I am also having this problem. It always shows the attachments twice. I have Norton 360 installed on my computer but I have the email scanner disabled. Also when I forward a message like this then it forwards the attachments twice also and then it shows two attachments even in webmail.

  • Same problem here: Win7, Outlook 2010, Gmail via IMAP, MS Security Essentials. Anybody found a solution yet?

  • I also posted this at Google's forum too: . Maybe describing your problem there as well brings us closer to a solution.

  • Outlook is now duplicating attachments with all IMAP servers, not just Gmail. If it wasn't a de facto standard I would stop using this horrible program.  It started doing it last night for unexplained reasons.

  • Still no solution???? I have the same problem.

  • I also have a user with the same issue. She is using Windows 7 Pro and Office 2010 and continues to have emails with duplicate attachments when using an IMAP account. Has this issue really not been resolved yet? How could Microsoft let this go so long without fixing it with so many users affected??

  • Same problem here. Outlook 2010 with WinXP-SP3, IMAP account, no Email filtering.

    This is really annoying - especially since so many people seem to suffer from it but you don't find a solution. :-(

  • +1 for user with same issue.  Outlook 2010 with (2) IMAP accounts, Windows 7 Pro, AVG Free anti-virus.  No content filtering.

    Really annoying glitch.

  • +1 here too. Outlook 2010 with 6 IMAP accounts, Outlook Hotmail connector for The problem seems to occur mostly (perhaps only) in subfolders of my Inbox. Attachments of emails in the Inbox seem to be unaffected. Moving an email to a subfolder did not immediately duplicate attachments.

  • This is an ongoing problem, but not consistent.  Occurs throughout the year off and on.

    Running Standalone (non Exchange) MS Office Home and Business 2010 64 bit - all updates current

    Dell XPS 256, Windows 7 Home Premium Service PAck 1 build 7601

    Outlook configured with 4 IMAP email boxes....three from Provider Network Solutions and one is gmail.  Duplicates do not occur with gmail....but I haven't specifically tested that.

    This is actually one of least annoying things about IMAP and Outlook by the way.  Yes, I read about 2013 fixes but it doesn't address the list I have.

  • Can Microsoft be considered seriously as a company that looks after it's clients?

    This issue remains unresolved and the answer for me is not to upgrade to 2013 because MS keep on doing this, expecting customers to upgrade in order to fix problems. There will be problems in 2013 that customers will have to upgrade to 2015 or whatever version....and the cycle continues.

    This issue for me is occurring with the Outlook connector to my account, not IMAP.
