We are running Exchange 2000 on our server with Online Web Access (OWA). When users access this from a Windows 2000 or Windows XP computer running Internet Explorer 6, there are no issues. Although for computers with Windows XP or Windows Vista running Internet Explorer 7, users face ActiveX controls that will not fully load. The following messages are from a XP with IE 7 after clicking on the button to forward an email.
"This website wants to run the following add-on: "Microsoft (R) Dynamic HTML Editing Control" from 'Microsoft Corporation'. If you trust the website and the add-on and want to allow it to run, click here..."
after the user clicks to allow, the page refreshes and changes the title of the menu to cannot find server and the standard page cannot be displayed message.
My initial idea is that since we have security in place to prevent buffer overflows, we restrict the length of web address typed in the address bar. But IE 6 users get no such errors.
