WEBES won't report all events to MOM

[Jan van Meirvenne]

I have a MSA2312fc hooked up to a WEBES 6.0 installation. there is a SCOM2007 installation with the HP Storageworks MP 1.5.3

When the MSA generates a critical alert, webes picks it up but doesn't forward it to SCOM (test alerts do arrive in SCOM), in the notifications-page of webes, I see 'Undelivered: MOM' for all of the MSA events. Dispatching the events again gives the same message.

Any idea why this wouldn't work?

thank you in advance!
