Exchange 2003-OWA

[Bankesy]

Hello

 

Does anybody why OWA powered by Exchange 2003 would be doing the following:

 

Basically no attachment is automatically allowed and deemed safe. All messages with attachments come with the warning about being potentially harmful and either have to be saved prior to opening or open following a message regarding security certificate.

 

This is only happening in Outlook Web Access, going through Office Outlook is fine.

 

Is it something simple?

 

Thank you in advance.

Hmm what browsers are your users using?

Hello

 

Everybody here just uses Internet Explorer 10. I've tested in Internet Explorer 8 and the files open in the browser if they don't first require saving.

 

I did already read that article and found the registry entry and the files I refer to aren't in either list, this problem occurs for the simplest of files such as .doc, .docx and .pdf for example.

Is your Exchange 2003 server up to date? And do you deploy the latest certificate updates to IE10 using WSUS for example?

Is IE10 in compatibility mode? e.g. IE8?
