Winmail.dat appears on all emails sent from Outlook

Posted on 2009-12-17
Last Modified: 2012-06-22
Have a client where this only happens from 1 pc out of 40.  Ooutlook 2007 with SP2.  Whenever this client sends emails (with or without attachments) to a specific user's Droid phone, he receives a winmail.dat in the email.  If she sends just text in the email, he can see the text and gets the winmail.dat.  If she sends an attachment, he can't read the attachment and only sees the winmail.dat.  If she sends an email to my windows phone, I receive it with no winmail.dat.  I she sends him an email from OWA, it's fine.  If other office users send him emails, it's fine.  I've tested by stopping antivirus, tried chjanging format of sent emails setting to plain text, etc to no avail.  Others who send to the Droid phone have the same Outlook settings as she and no problem.  The only thing I haven't tried is to uninstall Outlook and reinstall. It looks like it is relegated only to this person's Outlook. FYI - This customer has an Exchange 2007 backend. Anything I'm missing here?  Thanks.

    How to Configure Outlook NOT to send Winmail.dat attachments

    To Turn off Rich Text sending for messages in Microsoft Outlook

    1) Click on Tools
    2) Click Options, and then click the Mail Format tab.
    3) In the Send in this Message Format list, select Plain Text, and then click OK.

    This will set your default sending method to Plain Text, which will lose your special formatting options with fonts, colors, etc. However everyone, no matter what email program they are using, will now be able to receive your email with no problems.
