TIFF attachments may not be shown correctly in OWA 2007 and show RED "X" instead

Issue: In a Microsoft Exchange Server 2007 64-bit standard version environment, using windows 2003 64bit-version. We send e-mail message by outlook 2000 in Rich Text Format (RTF) format and attach with tiff attachment.

We found that the tiff image attachment cannot display correctly. the icon shows as a red "X".

Other attachment icons are shown correctly. The problem also exist when recipient use OWA2007.

Issue description: The icons that represent TIFF attachments may not be shown correctly in OWA 2007

The problem was that Internet Explorer (IE) cannot render TIFF images. It can render JPG, GIF, BMP and etc, but not TIFF. In Outlook 2003 and earlier, Outlook Express, and OWA, all use IE to render HTML. Since IE cannot display the TIFF, we get the red X. Outlook 2007 uses Wordmail to render all messages, and since Word can render TIFF files, the messages are displayed properly.

Workarounds:

1.       Use HTML or Plain Text instead of Rich Text when composing the message.

2.       Change the image format to something supported by IE (GIF, BMP and etc)

3.       Don’t send TIFF’s inside the message body, and attach them in the zip file
