    Why do I sometimes receive email attachments in the body of the email and how can I download and print from there?

    To save attachments, a couple of options include: (1) control-click on attachment, select "Save Attachment...", (2)  Click on "Show Details" in the upper right corner of the message, which then gives you some attachment functions including "Save".

    I can't open them without buying software when the same emails on my iPhone have the attachment as a PDF and open?  Thanks

  • Exchange 2010 sends attachments as winmail.dat

    Hi
    Some users are complaining about pdf attachements they received as winmail.dat. This is an internally isue.
    For external mail flow I disabled tnef conversion, seems to work. Is there a possibility to do the same thing for the internal mail flow?
    Regards

    Hi PeterN22,
    Winmail.dat attachments are included in received e-mail messages is because the Winmail.dat file is used to preserve formatting that the sending
    client includes in the message, but the receiving client does not recognize the Winmail.dat file.(The original message attachment is not always separate from the Winmail.dat file attachment, and may be included in the Winmail.dat file attachment.)
    So it is important to clarify what clients were involved in both the sending and receiving the messages in question.
    If this is occur in Outlook, here is a related document for you:

  • I cannot send or receive email attachments that are password protected

    I am able to send and receive emails with UN-password protected documents, but ones that have are protected or have protected fields within the document I cannot send or receive. Additionally, I do not get any notification that the email was not accepted; BIG problem!

  • Meeting Room emails are in German date format not English

    Hi,
    We've consolidated some Exchange servers and this has included creating some Meeting room resource mailboxes on our German Exchange 2010 server (Sp1 + update rollup 3v3).
    When a user gets a reply from the meeting room (E.g. if the meeting room is already booked and it conflicts with someone else) then the message is sent showing the time and date as:
    Organizer and Time of Conflicting Meeting 
    Username - Montag, Juli 11, 2011 1:00:00 to Montag, Juli 11, 2011 1:30:00
    It shows Juli instead of July and Montag instead of Monday. Does anyone know if this setting change be changed? If so is it a property of the mailbox or is it a property of the resource attendant so if I change it for one mailbox it will affect every other
    meeting room?
    Thanks,
    Joe

    Hi Joe,
    Thanks for your update.
    Reboot the server sounds low technical but it actually resolved many technical issues. So go ahead and have a try.
    Based on my research, whenever Exchange returns the decline DSN message, it generates the date time in the format of the original message (meeting
    request). To be more specific, it is the property "PR_Message_Locale_ID". It is also worth to verify this attribute.
    So, please verify the following attributes:
    1.   
    The "PR_Message_Locale_ID" of the original meeting request (which was declined) from Sent Items via MFCMAPI tool.
    2.   
    Check the language code of the problematic e-mails using MFCMAPI, “PR_INTERNET_CPID” and “PR_MESSAGE_CODEPAGE”.
    You may download MFCMAPI from

  • .docx attachments showing up as winmail.dat files

    My wife and I both have comcast.net emails.  When the secretary at our church sent both of us the same email with a .docx attachment, and we open the email on our IMac with Mail, it shows up under my email as a .docx (which I can open and read) but it shows up under my wife's email as a winmail.dat file.  Why?

    Yes.  Our incoming mail servers are the same.  When i go into Mail Preferences and look at Accounts, everything iin all three areas (account information, mailbox behaviors and advanced) are all the same except for our individual email addresses and passwords. 
    I just noticed by going back to some older emails in my wife's account that she has received .docx attachments from other church members (and they open up just fine).  This would lead me to believe that it would be some setting on the church secretary's computer. I will forward your above referenced article to our church secretary and have her be sure her settings are set as recommeded. 
    I am still baffled, however, as to why my Mail account has not had this issue, and my wife's has.

  • Attachements showing up as winmail.dat

    I just moved from a Windows XP machine to a MAC and I'm having problems receiving attachements.
    I'm using Entourage as my mail client.
    I've sent some emails containing attachments to myself recently from my Windows machine using Outlook 2003 and to other people with our company.
    When look at the email on my MAC their is no attachment but a winmail.dat file.
    If I look at the email back on my windows machine it is corrrect (Both Outlook and Entourage are configured to check the same account). I quized the other people within our company as they are also using MACs and they stated the attachments came thru fine.
    Any idea why the problem seems to be unique to my new MAC?

    The above answers are absolutely correct. And to give a little more information on this problem, I am quoting this almost verbatim from John Rizzo's recent article in MacWorld magazine:
    =================
    It's bound to happen. Occasionally, you'll receive an un-openable email attachment named winmail.dat from one of your Windows friends, and he or she will insist that the attachment was a Microsoft Word file or some other type of a file.
    First things first: DON'T BLAME YOUR MAC!! The fault lies on the Windows side, in Exchange Server & Outlook for Windows. When Outlook sends an email message in Rich Text Format over the Internet, Exchange Server sometimes creates an attachment called Winmail.dat, containing the message and some encoding data.
    One quick fix is to download and install the utility "TNEF's Enough" on your Mac:
    http://www.joshjacob.com/macdev/tnef/index.html
    This utility can extract a Mac-usable file from a Winmail.dat attachment in a few seconds.
    But running that utility all the time will get old pretty quickly if your friends are sending you lots of attachments and they're all winmail.dat files. If you're getting lots of attachments like this, an even better fix is to ask your Windows friends to turn off RTF in Outlook for Windows. They would choose Tools->Options, select the "Mail Format" tab, and then specify "Plain Text" in the "Send In This Message Format" list, and then click on OK. Once they do that, you will not receive those winmail.dat files in the future.
    OR, the best of all fix would be for them to point their network administrators to the Microsoft Knowledge Base article "How to Prevent the winmail.dat file from being sent to Internet Users" at http://support.microsoft.com/kb/q138053/

  • Why does my iphone not open email attachments?

    Iphone 4S IOS6.1.3 has stopped letting me open email attachments such as  Word, Exel and PDF. Instead it throws up a dialogue asking me to open it in another application (like 'Mail' ironically). Other Word docs present themselves as 'winmail.dat' format attachments. what the **** is going on? I need the iphone to read office attachments like it used to. I have 'reset' iphone using power and home buttons. Made no difference.
    Anyone know the answer?

    It could be for any number of reasons. Since you do not identify the computer OS you use, here is information for both.

  • Different Date Formats on CRM and BI Client

    Hi,
    When trying to run the CRM Interactive Report "Accounts with Open Activities", I receive the following error:
    Different date formats on CRM and BI client 01/13/2009 13.01.2009 SC5CLNT200
    Does anybody know how to resolve this error?
    Thanks

    Hi Peter,
    As far as i remember, I had the same issue.
    Once I matched the date format in reporting client using SU01 on default tab with CRM date format, I did't see the error again.
    Did you try restarting the Browser & also relogin GUI.
    Else lets see what else can be done.

    Hi,
    The Winmail.dat file is used to preserve Rich Text formatting. Outlook uses it when sending a Rich Text-formatted message. During transport, the content of the message may be changed, preventing the receiving client from being able to read the formatting
    instructions. In other cases, the receiving client does not use or recognize the winmail.dat file.
    To prevent or work around this issue, please refer to this similar thread
