    My wife has a new iMac with Snow Leopeord. When she sends Microsoft Word

    attachments, some recepients using Outlook recieve them with the correct file

    extension (.doc or docx), and some receive them with a .dat extension. Is

    there a setting in Outlook to allow the correct extension to be be maintained?

    Regards,

    Is she sending a Rich Text Format e-mail. That is the primary cause of

    > .dat issues. Change to HTML or Plain Text.

    So your wife is sending attachments from a mac and the outlook user's are

    getting them with the dat extension? What mail client is she using? What

    version of Outlook do the recipients use?

    There was an issue a long time ago where attachments sent from a mac and

    received by outlook were not visible until the recipient hit Forward but

    that was fixed in an update at least 2 yrs ago (id not longer).

    The ones receiving e-mails with .dat attachments are those that are NOT

    using Outlook. TNEF format (which is one RTF spec) is a proprietary

    document format from Microsoft that only their Outlook e-mail program can

    understand. Not even Microsoft's Outlook Express understands RTF. That

    means the only recipients of your RTF e-mails that can view them as you

    composed them would be those that are also using Outlook as their e-mail

    client (or those that have installed a 3rd party RTF viewer app).

    The only time you use RTF is when you can guarantee the recipient also uses

    Outlook, like within a corporate environment where all employees are

    required to use Outlook. Since you cannot guarantee what e-mail client is

    used by the recipient, compose using plain-text or HTML format.
