I am often (10-20 times a week) getting the following alert:

EAS account: Please press the Sync button

I have my EAS account scheduled to sync contacts and events every 30 minutes but not e-mail as I use Chatter. If I press Sync, it will go through a 5 minute process of replacing everything. If I dismiss the alert, it will just come back again in 5-10 minutes.

Any ideas why this is happening? I have a centro configured the same way to the exact same mailbox and it doesn't happen with the Centro only my 755p.
