I work in the IT department for our company and we have one employee that is experiencing difficulties trying to access e-mail attachments within OWA. When he attempts to open an attachment, the link to it is grayed out preventing him from opening it. If he tries using the link for "Open as Web Page", a new IE window opens and he gets an error message stating "The document cannot be opened as a Web Page. If the problem continues, contact technical support for your organization". From there he can click on the link for the attachment that is at the top of the new IE window and it will allow him to save/open the attachment.
This employee is the only one experiencing the issue and it seems to be localized to his computer since I can log in with his credentials from my desk and access the attachments without a problem. He has a new Dell E6510 with Windows 7 Pro 32-bit, Internet Explorer 8, and uses a satellite internet connection. We have many users with this same setup that work fine. The laptop has a fresh install of Windows on it and is definitely spyware/virus free. I have verified that the security settings within IE are all set to default, that our domain is included within the Trusted Sites, and that there hasn't been any addons installed within IE.
Our exchange server is currently running Windows 2003 R2 x64 with Exchange 2007. I don't think this is a server side issue though since it is only this user and it only occurs from his laptop. Any ideas/suggestions?
