Help EVO vibrating like crazy - seemingly with no new email

[bc_co]

OK - I know how to turn the alerts on/off - ring vs. vibrate for all of my email accounts - corporate, and 2 personal.

I could swear that often, when I'm not receiving any email on any of my accounts - my Evo vibrates - seems to be in batches of 5 - up to 15 times in quick succession. Not that big of a deal when I'm at work (yes - receiving corporate email) but at night when I have the phone on 'quiet' it often vibrates - and I check all email accounts - nothing new. Yes, this has the potential to drive lesser people crazy....

Anyone solves this for me - it's a bonna fide high-five situation.

Thanks
