Unable to attach files in OWA

    Question

  • Hi all,

    After a recent server restart applying a series of Windows Server 2008 updates, my Exchange 2007 has stopped accepting files uploaded via OWA. The client version is 8.1.436.0 Premium.

    The sequence of events is;

    1) Create a new email OWA;

    2) Attached a file.

    3) Hit send.

    The window that has been opened to send the email is left with the sending graphic stays open for a long duration before a message of "

    Microsoft Exchange issued an unexpected response (12031).
    "appears.

    More troubling is that since both the Premium and the Lite versions of OWA have the same problem. The server appears to stop responding after attempting to send an email with an attachment.

    Any help would be apprieciated.

  • Here is one solution from research. If you're getting these red X's it's typically firewall, proxy, AV related.

    "In the last 2 weeks, 2 out of 3 people at my company are having issues uploading attachments to their e-mails, as well as having problems with sending e-mails out using Outlook Web Access. Whenever they try to upload attachments or send out e-mails through OWA they receive the error "Microsoft Exchange issued an unexpected response (12031)"

    The issue ended up being AVG Internet Security Business Edition. Even though I had turned the firewall off after a failed attempt at setting it up properly, the service AVG Watchdog was still blocking OWA e-mail traffic hence creating the error 12031 in Outlook. Once I completely disabled AVG, all my clients were able to use OWA with 0 problems. Once Microsoft walks me through how to setup AVG so that there will be 0 conflicts between it and OWA, I will post the resolution and then close out the case.

  • Yeah, I read that one and that is not applicable to my problem. I checked my firewall and traffic over 443 is not dropped. If the firewall was dropping packets/connections as a consequence of the file upload attempt, I do expect to see a notification. There is no notification so I can only assume that it is not interfering with the traffic.

  • What updates were applied?

  • Sure, all of them? ;) I think the most significant update was the Exchange Update Rollup 10 - thats when the issue started to become apparent, it's just since the last reboot last week that it's become most apparent.

  • So let's focus on the Exchange Rollup. Anything in the Exchange Setup logs ( including UpdateOwa.log) that show maybe it didnt complete correctly? Was the Exchange Rollup installed with an account that has Exchange priviledges and run as elevated?

    One option would be to run the updateowa.ps1 in the /bin directory as elevated and see if it fixes things. Another would be to remove RU10 and/or reinstall.

    You should also think about moving to at least 2007 SP2 at some point.

  • Ok, so both the updateowa.ps1 and removal of RU10 has had not effect, apart from confirming a downgrade to OWA Client Version 8.1.393.1 which I was hoping would resolve the issue. However, attaching files is still failing although this time the attach file dialog box blanks out and remains.

    Whats so frustrating is that both the developer tools results for captured network traffic clearly show the click on the attach button but the server side does not log any post for the file dialogue subsequant to the initial GET.

    I am now going to try re-installing RU10 to see if that helps.

  • Still no joy - back to version 8.1.436.0 and the attach file dialog just will not load a file.

  • A call to Microsoft Support may be in order. Is this a multi-role server or CAS only?

     

    Tuesday, February 22, 2011 2:11 PM
  • It's multi-role, AD, File/Print server, Exchange (obviously) and thats all.

     

    That said, I stopped the default web site for a good 10 minutes late last night and then started it up. The good news, I was then able to attach files to emails using the Premium interface.

    The sad news, is that a limited number of users still report the issue. This means it's not wide spread. I have forced some test users to delete their temporary files within IE but this appears to have had no impact.

  • What if it's not OWA on IIS - but something in IIS ?? Maybe IIS is saying that file is to big, or taking too long, or it just isn't handling receiving the file?
