Everything was working fine until may 6th. I have 4 accounts syncing. 1 Gmail, 2 Google Apps and 1 Hotmail. The Hotmail account was setup via POP3.

It was working perfectly until May 6th. Now, the little green "online" light is grayed out and when I press the "Send/Receive" button, nothing happens.

All other Google accounts continue to work fine. I logged into my hotmail account via browser and it is working fine.

Is there any recent change that could be impacting Hotmail sync?
