Attachment in Outlook renamed

  • @fbartels
    So you don’t think it would make sense open a ticket with kopano support?

  • I just opened a support ticket with kopano.
    I’ll let you know about the answer.

  • Kopano

    open a ticket with kopano support?

    If you need an official statement its always best to contact the Kopano support directly. This here is just a community forum and it comes without guarantees.

  • hello together,

    I have no good news. My Kopano Support-Ticket was closed. They where able to reproduce the issue with for example Outlook 2013 and Outlook 365 and confirmed that in the z-push.log everything is shown correct (because of this the attachments are displayed correct on the smartphone).
    But this brings them to the conclusion that this is not a Kopano or z-push issue but more a Outlook issue.
    Because of this there is nothing to solve for the kopano support.

  • Outlook for the win.

    Guess what. Microsoft will close the ticket as well and tells you to reinstall Outlook, or better, make an online repair.

    Best thing would be to revert Outlook back to an old version but I dont know how. This self updating click-to-run thing is a pain in the …

  • You can actually revert back to previous version quite easily.

    1. Deactivate the Ms Outlook updates in outlook (File -> Office Account -> updates
    2. Launch administrator command prompt and then execute
      C:\Program Files\Common Files\microsoft shared\ClickToRun>OfficeC2RClient.exe /update USER displaylevel=True forceappshutdown=true updatetoversion=16.0.13127.20296

    With the version being the version you want to revert back to. You can check versions on the microsoft website. I have been testing with reverting back to the 31/08 Outlook 2016 version but the problem is still there… :-(


  • This is the official MS link that explains the downgrade for the different versions:

  • All,

    I have reverted back to the following version and noted that when you move an outlook item that has the issue to another folder and back. It is being displayed correctly.


    So workaround, one can apply for now is reverting back to the yellow version above.


  • Hi guys,
    I also had success by reverting back to an older Outlook version.
    Office 2016 H&B
    Version at start: 2009, Build 13231.20262 Click-and-run

    First, I deactivated automatic updates in the settings of outlook. Then in CMD I ran:

    cd C:\Program Files\Common Files\microsoft shared\ClickToRun
    officec2rclient.exe /update user updatetoversion=16.0.12827.20470

    Version at the end: 2005 Build 12827.20470

    I made a new Outlook profile - the existing one did not automatically resolved the right filenames. I did not try moving Mails back and forth.

    I intend to try the same on a MS Office 2019 H&B in the next days.

  • Heyho,
    Microsoft Support pretends to know about the issue with Outlook and renamed attachments.

    Es tritt ein Problem auf, bei dem Anhangsnamen für empfangene E-Mails wie folgt angezeigt werden. Das Problem sollte nur bei E-Mails auftreten, die von POP / Mail-Clients von Drittanbietern (wie Thunderbird) gesendet wurden.

    Das Problem is bekannt und sollte bei dem nächsten Fix-Update ghoben werden.

    A problem occurs where attachment names for received emails are displayed wrong. The problem should only occur with emails sent by third-party POP / mail clients (like Thunderbird).

    The problem is known and should be fixed with the next update.

    Yeah kinda close. Attachments also get renamed when using the Windows internal “Send As” function. But you nearly nailed it.
