      Hi all,
      we are experiencing the same issue. I tracked it down to the newest Outlook Versions. For Example 2019 x32 16.0.13127.20266

      Users with this versions will sometimes see this strange attachment name. If you connect this user via older Outlook they will see the correct attachment name, which you can also see in the Webapp.

      This happens not for every attachment nor every pdf attachment. There have to be some things coming together. Mailclient of the sender, attachment name longer than 10 letters and spaces or special characters like umlauts in the attachment name.

      You can reproduce it by sending an pdf attachment with Outlook connected via ZarafaClient and an attachment name like öäaaaasssssssssssaaa.pdf
      (Funny thing an attachment with the name ööaaaass.pdf would work).

      You can also reproduce this if you have an Outlook with the newest version and connected through Z-Push. Now you make a right click on a picture stored somewhere on your hard drive and choose “send to --> Mail client”. The picture will be transformed and attachted to a new Mail. The attachment name might look ok but after sending this mail, have a look at sent items. There the attachment name is kinda weird.

      Might be an transcoding problem which only appears with certain circumstances.

      Long storie short. In my case this problem appeared monday and without an update to Kopano in the last days. So my guess is, that this is problem created by Microsoft with a new Outlook update.

      —Edit—
      Z-Push Version: 2.5.2
      Kopano Version: 8.7.16

      —Edit 2 23.09.2020 12:13—

      In two cases the attachments ending was also changed to .dat
      This creepy issue comes and goes every since using Outlook and Kopano (Zarafa)

          dunno but i guess 2016 also recieves updates. Guess its like Windows 10 v 2004 and Windows 10 v1909. Different release but both are recieving security updates and fixes and one of them breakes the transcoding. Sadly i’ve no 2016 for testing purpose. And i’ve no idea how to revert Outlook 2019/16 to older releases.

          @ekpack does the renaming happen to every pdf attachment recieved by Outlook?

            No, not to every pdf. But it also happens to other filetypes like docx or xlsx.

            And it also happens to sent emails not only to received mails.

              Same Mail in different Outlook versions

              Maybe someone got an idea for this.
              Sadly we also got mails where the fileending is xxx.dat
              Hard to explain the users that this could possibly be opened with Arobat Reader.

              —Edit—
              a very old post for Mozillas Thunderbird.
              But this looks like the best explanation for this issue. Especially for the type of files which are renamed. Not only filename character length but filenames exceeding a 64bit character length
              http://kb.mozillazine.org/Attachments_renamed

              Still dunno if this is only an issue related to a faulty Outlook patch. But maybe someone at Kopano can reconstruct this issue and has an idea

                I have exactly the same happening. Also with outlook clients and starting since last week. It’s not with all clients and not all emails. Seems to happen mostly with XLSX and PDF attachments. Does anyone know how to fix this on the client side?

                regards,
                Joost

                  I’m also suffering from this problem. When I investigated it, it happened when using the file => right click => send to email recipient method of attaching a document, but not when attaching the document in outlook 2019 directly.

                  But it also was not happening at all when sending out the (right click => send to email recipient) attached mail using a simple -non-kopano- IMAP account.

                  I’ve also seen this with some received emails! Where the filenames were broken in Outlook but OK in DeskApp. Weird!

                    We have the same issue here since 1,5 weeks … sometimes attachments are renamed (eg. thefile%25%36%43%37… .dat)

                    kopano-core: 8.7.16
                    z-push: 2.5.2+0-0
                    Outlook 2019 with OLE 2.1-20 installed

                    Names of attachments are ok in DeskApp, WebApp, and Android mail app (synced via z-push activesync)

                    Kind Regards,

                      Same here.
                      Customer reported first it happened with mails from a scanner, but now it happens randomly, mostly with longer filenames.

                      Outlook 2016 and 2019.
                      Tried with replacing font-files on the PC’s, but did not help.
                      Furthermore one of the PC’s uses calculation-software based on excel, and it shows also strange artefacts (euro and diameter-character no longer recognised, etc).

                      My conclusion was it was some Office update that screwed up. But now that I saw this thread I will be interested if someone finds a solution.

                          That would still be my conclusion. From what could be read here so far the problems started after updating Outlook and happens with various versions of Kopano and Z-Push. I would recommend opening up a case with Microsoft.

                            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.

                                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
                                        e.G.
                                        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… :-(

                                          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.

                                          debeb163-c4a9-4b0e-92b4-1834d7c556d8-image.png

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

                                          regards,
                                          Joost

                                            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.
