Error message when you try to open a 2007 Office system file attachment in Outlook Web Access
SYMPTOMS
When you try to open a 2007 Microsoft Office system file attachment by using Microsoft Office Outlook Web Access, you may receive the following error message:
To open this attachment, you must save it to your disk, right-click the link, and then click Save.
This problem occurs if the following conditions are true:
| • | The e-mail message is sent by using Outlook 2003 or by using Outlook 2007. |
| • | You read the e-mail message in Outlook Web Access. |
RESOLUTION
To resolve this problem, add the 2007 Office system content types to Exchange so that the conversion process can recognize these content types. A content type is a string that has a file name extension associated with it. To add the string and the associated file name extension, use Exchange System Manager. To do this, follow these steps:
| 1. | Open Exchange System Manager. | ||||||||||||||||||
| 2. | Expand Global Setting Branch. | ||||||||||||||||||
| 3. | Right-click Internet Message Formats, and then click Properties. This operation displays the current list of known MIME content types. | ||||||||||||||||||
| 4. | Examine the list, and confirm that the 2007 Office system file name extensions are not in the list. | ||||||||||||||||||
