I get this error whenever I try to manually refresh my Exchange email account. I noticed I hadn't received any emails all weekend, which was odd. I booted up my iPhone, and there were 7 new emails. My Evo (which has all my previous emails in it) doesn't show these. I was not connected to WiFi (we aren't allowed to have it at my work) when I initially setup the account, and I've since tried through my home WiFi and through 3G. Sync Schedule set to: As items arrive Under Accounts & Sync: Exchange ActiveSync is enabled Any ideas?
