I am running Exchange 2013. When I open an email with 3 jpeg attachments in Outlook 2010 I am able to view the attachments. When I open the email attachment in OWA and click on preview I get the message "This type of attachment must be saved to disk. Right click the link and the click Save Link as to download the file". When I do this it saves it as a Firefox HTML document. When I click on this file I get the message "Outlook Web App requires your browser to use UTF-8 encoding. For your protection, you'll be signed out. Please set your browser encoding to UTF-8 and sign in again". My Firefox browser is set to UTF-8.
How can I view/download these jpeg attachments in OWA?
