You have inserted an attachment file type that is blocked by Microsoft Outlook
for security reasons. These file types, such as .exe, .bat, .scr, and .js, are blocked because they can potentially contain viruses.
Recipients who use Microsoft Office Outlook 2003 or earlier versions of
Outlook that have been updated with a security patch will not be
able to open the attachment. By removing the attachments with these file extensions from
your message before you send your message, the recipients can save and open your
attachments.
Delete an attachment from the Attachments box
- Right-click the attachment.
- On the shortcut menu, click
Remove.
Delete an attachment from the message body
- Click the attachment.
- Press
DELETE.
Tip

attachment, and then press BACKSPACE twice.
Note If the message
is in HTML format, attachments appear in the
Attachments box, located below the
Subject box. If the message is in Rich Text
Format, attachments appear in the body of the message.
