Actually I'm having this same issue and even a manual send/receive will not get my email. I don't want to hard reset because it tkes too long to get all my setting back. As much as I love the look and feel of this ROM I don't think it is functional for me because of the Exchange glitch and the following:
1. Activesync doesn't connect to my device anymore. This is trouble because I have no idea how I'm going to flash back to stock ROM
2. Both my Exchange and my Hotmail accounts no longer sync. Actually I can't even send/receive manually
3. Sprint Picture Mail doesn't work anymore
4. Task Manager shows that my CPU usage is over 50% with no running programs. stock ROM was rarely over 38%. I notice a definite lag - even greater than stock - when trying to open memory intesive programs like photo album, etc
5. Wierd black box that covers the reception/speaker icons on the top bar. This comes and goes as it pleases (screenshot attached)
Any ideas on how I can revert to stock without activesync? Any suggestions to make this ROM work as well for me as it seems to be for everyone else?
