If you use the Microsoft Outlook email client and the people that you send email messages to report that your messages are arriving as "winmail.dat" files instead of text, do the following:
- Open the Outlook Tools menu, select Options, then Mail Format.
- If you see a "Compose in this message format" option, select Plain Text or HTML.
- If you see "Send Mail as Rich Text Format (RTF)" and "Let Outlook choose best format" options, make sure they are NOT selected.
If you require assistance with this issue, contact the ITS Client Services Center at 212-998-3333.
