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?
