Hi All We have just installed SBS 2011 and Exchange server and have about 8 users using Outlook 2007 and Win XP This is a new installation, having never used Outlook in the office before. For antivirus We have AVG on the workstations and Clamwin on the server. All working well except quite a few, say 10% of emails we receive are missing all content. We have to ask people to resend to say a Gmail account so we can read it. This appears to be happening randomly. I suspect it is an outlook thing. Any ideas?
