if using U403, open Port Status Monitor (PSM) from Tools Depot. If not,download from www.ciscounitytools.com
I'll assume there is no problem hearing the vm on the phone.
Leave one person a message. Do you see Dial MWI 'extension-xxxx' once or many times, or none at all.
If once, the message was sent to ccm but light did not come on - perhaps due to incorrect mwi-code (possible if you have more than one VM profile)
If more than once, VM-ports's CSS could not reach the phone extension Partition. You will see a harddevice setmwi error in the app logs.
If none at all, then it may appear that Exchange never told Unity. Try going to the subscriber page, and click refresh - do you see MWI dialout on PSM?
Here is a doc to help you through it.

Look through the w2k application-event logs. There's usually something there.
Do let us know if this has been any help.
