Attachment file extension is duplicated when added to email in Outlook 2007 and Outlook 2010
When you drag an attachment to a Microsoft Office Outlook 2007 or Microsoft Outlook 2010 email message, the file name extension is duplicated. If you then drag the attachment from that email message to another email message, the file name extension appears in triplicate. The pattern continues as you drag the attachment more times.
Additionally, you cannot copy an attachment which has a file name that contains the pound (#) sign or symbol, and paste it to another message.
Note Outlook 2007 uses Microsoft Office Word 2007 for the rendering engine. Similarly, Outlook 2010 uses Microsoft Word 2010.
