Klammer - no permission to open winmail.dat files

Up to now I have been able to open Winmail.dat files without a problem. Suddenly I get the response "Not permitted to open the file"; When I check the file in Finder I have the rights to read and wright. Here I am stuck. Would appreciate some advice.

Try enolsoft winmail viewer. It works well for me and supports Mavericks. You can find it from Mac App Store.

  • Open winmail.dat files?

    Anyone know how to open winmail.dat files?  I've been getting email attachments which I can't open on my MBP. 

    Hi ,
    The person that is sending you emails, has chosen in Outlook, to use the RTF format, for emailing and or specifically for emailing you. Perhaps this is default Outlook behavior at times.
    This results in the winmail.dat file, which is the RTF format, of the attachments that were intended for you.
    If the user would configure Outlook, to use the HTML (web)  format, for emails, then you would receive the attachments as intended. As well as anybody else.
    Apple mail and other mail systems, do not understand the RTF (rich text) format, and probably have to pay Microsoft licensing fees, to be able to use this format.
    The options, for setting this in Outlook, differ for different versions of Outlook, but are found generally under
    Tools > Address book, for setting a specific person to , use HTML format, and not RTF format, that persons email.
    Also, under "Tools" > "Options", > "Mail format", for setting that all emails, will use the HTML format, instead of the RTF format.

  • Opening Winmail.dat files in Mail on iPad (Ms Windows Word, Excel, Ppt)

    I thought I'd share my findings on what to do if your Word, Excel, Powerpoint attachments come into your Mail as winmail.dat files. In my experience I downloaded the following Apps:
      Pages
      Numbers
      DocsToGo
    WinMailViewer
      Letter Opener
    To open the winmail.dat file hold the icon until asked how you want to open the file: WinMailViewer or Letter Opener (assuming you've previously downloaded both Apps).
    WinMailViewer is exactly what it says ... a 'viewer' of the file.  The file is sent to the relevant App which you subsequently open to see a list of the files.
    Letter Opener will bring up the attachment(s) in a separate window and gives you choices on which App you'd like to use to open or view the file with. Depending on what Apps you've previously downloaded:
      For Excel it might list: Quick Look, DocsToGo, Csv File Editor, PDFReaderLite
      For Word, it might list: Pages, DocsToGo, PDFReaderLite
    DocsToGo is an excellent option for working on Word, Excel files (N.B. If you have a big Excel file with 'frozen' window panes, I recommend clicking on the 4th tool (bottom toolbar) UnFreezing the panes while you work or move around the file as I haven't figured how to work with it on!!)
    Pages is the best option to use for editing Word files.
    Numbers is probably the best option to use for editing Excel files.
    Csv File Editor is another Excel editing option.
    I hope that helps.

    I should further say the files I sent are .xlsx and .docx files.  They look fine my end and I send such files all the time without problems.
    However, I did try to cheat by going in via the Safari onto my 'live' online email account and the Safari automatically transfers them to winmail.dat files with the same result.
    Ahh - have just been on using my PC this time and you are right, it seems that the service provider does the transfer and then when my outlook opens the file (on the PC), it must reconvert to .xlsx etc again.
    Very strange.
    Ergo, I guess the question should be how I open wimail.dat files ??

  • HT2614 Is there a way to open winmail.dat files on a mac pc?

    aparently winmail.dat files ar created by microsft outlook or simular mail clients on a PC and has somthing to do with rich text document settings. if i start my computer in windows mode i can view the files however if i start in MAC OS and try to open it wont reconise even if using the MAC version of Microsft outlook.

    That's a Microsoft extension.  For frequent email senders, you can request they stop sending the Microsoft-specific stuff; messages that aren't directly readable by other mail clients.  Here's how they can disable this: Email received from a sender using Outlook includes a Winmail.dat attachment (Microsoft KB278061)

  • Opening winmail.dat files on iMac

    I just purchased a new iMac for home use, but I still use it quite a bit for business purposes.  As such, I receive quite a few emails from Outlook users and people on Exchange servers, and consequently much of my email on the new Mac ends up as winmail.dat files or attachments.  Incredibly, Apple support says that the asnwer is simply to tell all my emailers to change the way they send their mail!  I can't believe that there's not a better answer or fix.  Does anyone have a better solution?

    Hi,
    There is a solution...

  • How do i open winmail.dat attachments in mail

    How do i open winmail.dat attachments in mail ?

    Having problems with Winmail.dat attachments?  This is really Windows problem but their hubris will not allow them to admit it. 
    Windows does have a global fix for this problem but it is not a general patch - in their KB there is a fix for Exchange servers which cause the winmail.dat problem but most users don't know about it or have it implemented. 
    http://support.microsoft.com/kb/138053http://
    Here is a solution that Apple users can get for $30.  An Austrian program and APP called Letter Opener http://www.creativeinaustria.com/http:// is the solution to seamlessly opening Winmail.dat files.

  • How to advoid Pdf attached files turning into winmail.dat file causing incovinience opening them? And why does the phone automatically changes the file???

    The first time i opened the mail, the mail loaded the attactment as pdf file and i was able to open it without any problems. But then when i tried to open it again, i watched the phone automatically turned the pdf file into winmail.dat without any of my control. Since then, i werent able to open the file anymore! And this was lucky that i was able to see it as pdf file - all other attachments i have recieved since using my new ip6 all turn into winmail.dat
    this is really incovinient and frustrating for work. i cant believe i cannot just open a pdf file as a pdf file on my ip6 in the emails i recieve. I was on ip4 before this and never have anything like this happened.
    Solution needed asap please.
    Thankyou!

    Hi Jnkm,
    I'm sorry to hear you are having issues with your new iPhone 6. If you are getting a winmail.dat file instead of a PDF, you may want to see if it may be the issue noted in the following article:

  • How can I get Mac mail to open winmail.dat attachments on lion 10.7.3

    How can I get Mac mail to open letter attachments winmail.dat??   (Lion 10.7.3) Any help appreciated...

    Sorry peterskine,
    it's true in part. There's more then one article on the subject "Recipients receive a winmail.dat attachment":
    http://office.microsoft.com/en-gb/outlook-help/recipients-receive-a-winmail-dat- attachment-HA010153018.aspx?CTT=1
    The odd thing is that my colleague and me use the same release mountain lion and we received the same email from someone on Outlook2007. He received the mail with the attachment, whilst I saw a "Winmail.dat". It already happened to me on snow-leopard, some month ago. Up til today I don't know what the difference between our machines is.
    But it is interesting: the same OS, the same mail-clients (Apple Mail) and still different results.
    Note: on my machine it used to work properly. It just suddenly happened that I started to receive winmail.dat files in stead of proper attachments.
    When I have more time on hand, I cant try to find out why this happens.

    In Outlook, I changed the setting for how the mail sent to each typoe to resolve the issue. I created one email per setting and addressed to both people on their corporate exchange account (same server for both) and their gmail accounts. This is where the confusion arose since one phone receives fine and the other doesn't. I used Gmail as an alternate mail client with the same result.
    So basically I used two different clients each time sending to four addresses two are located on each phone. Phone A always receives a winmail.dat file no matter which client or email address is used. Phone B always receives the attachment in it's correct format.
    I took it a step further and used the phones to test sending. Even if I use Phone A to send to the other account on Phone A, winmail.dat is received. If done from Phone B to Phone A, Phone A winmail.dat persists. Phone A to Phone B correct format is received. I'm thinking there is a setting somewhere on Phone A I'm not aware of that was somehow changed since it is not mail client dependant nor recipient mail server dependant based on the testing results.
    This is a Microsoft Windows setting with Microsoft Outlook or within the Exchange Server gateway in general.   These winmail.dat files have been arriving on Linux, BSD, OS X, Tru64 Unix, ULTRIX, Solaris and many other servers for many years, too — unfortunately, everybody that's using non-Microsoft clients and tools encounters these files from time to time.  The winmail.dat is a Windows Mail data file, after all.
    If the mail client or if the mail server gateway sends a mail message to an iOS device — or many other "foreign" mail clients — that involves a winmail.dat file generated by the sending client or generated by the originating mail server gateway, then iOS will show the winmail.dat file.  Like many other mail clients, the iOS mail client does not decode, process nor create these winmail.dat files.  (Most clients simply treat these winmail.dat files as an arbitrary attachment on the message.)
    Send the same messages to the same email addresses and read those messages via another mail client — one that doesn't have winmail.dat support — and you'll see the exact same behavior; a wad of attached winmail.dat data.
    From Microsoft: How to Prevent the Winmail.dat File from Being Sent to Internet Users.  In short, either the Outlook client settings or the Exchange Server (IMC) settings will need to be changed here.

    2- outlook 2003 as a client
    I know that exchange sends these files in rtf format is there a work around so i can read my documents !!!Message Edited by amrlotus on 12-Apr-200702:48 PM

    I tried changing the extension, which sort of works. I sent an email to my wife's iMac from my PC, which had several .jpg and one .pdf files attached. It shows up in Mail with a single winmail.dat file attached. I changed it to a.pdf, and it opened the pdfonly. I couldn't get the jpgs to open, even with a .jpg extesion.
    First of all, why in the world would it do this? Second, how do I open them since they are mixed type, and several at once? Seems ridiculaous that a Mac does this to attachments, BTW.
