The messaging interface has returned an unknown error Outlook 2007

    Question

  • Configuration : Exchange 2007 - Windows7 - Outlook 2007 & word 2007

     

    When saving a mail as *.msg, *.html or *.mht in Outlook 2007 on a windows-share our users sometimes get the following error : “The messaging interface has returned an unknown error. If the problem persists, restart Outlook”.
    The second time they try to save the same mail they don’t get the error and the mail is saved correctly.

     

    I’ve already tried : 

     

    ·     a full re-install of the windows7 + Outlook 2007 + word 2007

    ·     new windows profile

    ·     Install of all windows & office updates

    ·     repair of PST and OST files

    Unfortunately, the error keeps appearing with several of our users...and I’m running out of ideas.

  • I have a user receiving the same error message within outlook 2007, except my user gets it when trying to open another users calendar.  This user needs access to multiple calendars, and was recently upgraded to Outlook 2007.  I have repaired/uninstalled/reinstalled Outlook 2007 without any luck.  I will say that the message disappeared after each uninstall/reinstall, but the next day, sure enough it appears again.  I have found that the workaround, instead of reinstalling, for this is to Open the Calendars by going to File>Open>users calendar.  Once I do that we can go back in and use the check boxes without seeing the error message.

     

    The person in question is using Outlook 2007 with Windows XP. 

    Outlook is the only 2007 product on the machine.

    Word and Excel 2003 complete the suite on this PC.

     

    Thoughts?

  • I am experiencing the same error on our network.

    Users are setup with exchange profiles using outlook 2007 on XP, Vista and Windows 7.

    When some users try and save emails as EML to the sbs 2003 server we get that error. If outlook is closed and then reopened they can save the email.

    It does not happen consistently and it does not happen to all staff. I'm not sure if mailbox size is an issue or not as one of the users who has the most problems has a mailbox over 7gb.

  • i have a similar issue as well, when i try to delete mails from a personal folders file that resides on the computer, it gives me that error message.  i don't know how to go about it and i do not want to recreate the mail profile as the user as too many rules.

  • Has anyone found an answer to this yet? I have the same issue. WIN 7, OUTLOOK 2007, Exchange 2007, and saving to a network drive. I don't get it all the time, and it is VERY annoying.

  • Try the "repair" function of Office 2007
    If this wouldn´t work you can try "fixmapi.exe" (Start/Run: fixmapi.exe =>
    OK)
    You would not get any response after you start the fixmapi tool. Try to
    start Outlook.
    If this wouldn´t work:
    I prefer to create a new Outlook profile:
    http://support.microsoft.com/kb/829918/en-us

    or if still not fix

    Close Outlook.
    2. Go to c:\Program Files\Microsoft Office\OFFICE12 and run Scanpst.exe.
    3. Microsoft Office Outlook 2007 Inbox Repair Tool will open. Click browse and locate the PST file that you want to check.
    4. After you located the pst file, click the Start button.
    5. If errors are found, click repair.
    6. Start outlook and see if the .pst file is now working properly

  • This appears to be a Windows 7 related issue, i've had several users with this issue and havent managed to find out why because its so intermittent. Had one user on XP where it never happened, soon as they switched to windows 7 it happens.

  • This issue is triggered when MS10-020 (http://support.microsoft.com/kb/980232/) is applied to a windows System. Microsoft has released a hotfix for this (http://support.microsoft.com/kb/983458).

    This hotfix has been included in Windows 7/Windows 2008 Service Pack 1, hence solving your issue.

    For all (elder) operating systems (both client and server) that use SMB, you need to apply this hotfix.

     

    Regards !
