Sync Multiple Accounts

[pure]

I'm currently trying to sync a Yahoo, Gmail, Exchange, and Hotmail account, and while all sync, I must do them all, one at a time. I had to reinstall Zimbra and before when I hit the "send/receive" button, they all synced to their respective servers, however now I must do them all manually one at a time. Did I miss a setting, or is Zimbra malfunctioning?

I'd like to all sync when I press the button, it had been working in the past.

Can anybody help me with this. There are a total of 10 accounts that I use on Zimbra and updating them 1 by 1 is painfully slow. Is there a way to sync them all to their respective servers?
