Had that same phaenomenon as well. After deleting my MfE account and starting all-over from scratch I decided to only sync last weeks emails. Again the status bar showed everything ok and opening modest would now show "content" in my inbox. But there's only the subject line. Below that line (where I'd guess the sender's address would be) it reads "Kein Empfänger" which would mean "No Recipient". Also the time-stamp of each email is the time last synced, so emails keep getting "newer" each sync ;-) Ahh, and emails bodies are empty.
