I am having a problem getting a subscription notification from an external
content source when a change is made to it. The subscription is for a
complex link and there is a site rule that is created for it. The access
account has read rights to the content source. The email account to be
notified is correct and it is setup for immediate notification when a change
occurs. The immediate notification task for the workspace is running
correctly.

Any ideas? Could this be due to the complex link?
