Exchange 2003 SP2 Attachments can contain viruses that may harm your computer

We are running an onsite MS Exchange Server 2003 SP2 6.5.7638.  The user is running MS Outlook 2010 on her desktop and has a Droid phone with a corporate account setup.  Emails are showing up on her phone that DO NOT APPEAR in the desktop Outlook 2010 program.  The "missing" emails show up in OWA.  When I open the email they are flagged "Attachments can contain viruses that may harm your computer. Attachments may not display correctly."  I have determined that these emails are being sent via a MAC and an IPhone.  The attached JPG images are "inline attachments" to the message text.  Exchange is not configured to block any attachments.  I assume Outlook 2010 will not display the messages flagged to contain viruses.  What can I do at the exchange level to not have these messages flagged?  If there is not a solution at the exchange level, what can I do within Outlook 2010?

Thanks for your speedy response.  Please clarify.  What should I be looking for in the Outlook view settings?  By "Outlook online mode" are you referring to Outlook Web Access?  If so, what settings?

Switch outlook to online mode:

In outlook 2010 --> File--> Account Settings--> Email tab--> change--> uncheck the "use cached exchange mode" --> next--> finish-->restart the outlook and check

Hi,

I have the exactly same situation, server is running Exchange 2003, Outlook 2012 / Outlook 2000 is ALREADY ONLINE mode but can't display that email. Phone can view it properly. OWA is also display "Attachments can contain viruses that may harm your computer. attachments may not display correctly.".
Identified that attachment is xls from phone view.
I have revised the Protected View and Trusted Locations option of Trust Center Settings in Excel, however it still cannot display in Outlook client.
Any further advise?
