I am having a tough time sending attachments, in my email. When I attach a word document made in Word for Mac 2008. It leaves my mail program without an extension and arrives in the recipients mailbox as a .dat file. Is there something I can do to avoid mail from converting this file?

    Are you sending Windows-friendly attachments? You need to click on the Attach button in your message window, navigate to the document you want to send, select it, and check the box on the window that says Send Windows Friendly Attachments.

    I don't think it's Mail, since I haven't heard of anyone else having this problem, nor have I ever had it. You can also just make a .zip archive of the files you're sending and then attach them, and the recipient will receive them as they are.

    And if you haven't done it already, you should update to 10.5.4 and update your profile to reflect that.

    If in the location where this word doc file resides before attaching, you Control-click on it, and select Get Info, is the box to Hide Extension Checked or Unchecked?

    Also, although it should probably not matter, is the Word Doc of the type to have the extension .doc or .docx?

    Firstly make sure you save the document in Office as a Word .doc or .rtf and check the *_append extension button_*-THIS IS IMPORTANT all in the save as dialogue box.

    In mail check the send windows friendly files

    Whilst Entourage does re-encode Mail actually does Not.

    This .dat is an an indicator that you have Not appended .doc or .rtf when saving as windows has applied the standard default .dat binary code by default.
    If your windows friend simply remove the .dat from the file name and change it to .doc the document will the open in MS word completely un-corrupted !

    This it the classic windows reliance on those .xxx extensions to identify what programme is needed to open/run !

    It is quite plausible that the receivers email client (Outlook per-chance is screwing the file extensions actually)- Regrettably you are unlikely to prove or get any support from them or there IT department.

    Just make sure you add the .doc/.rtf code to files sent to windows.
