I am having trouble with my MS Exchange 2003 server local delivery. After a while my Local delivery will deliver mail at a crawl, it will slowly empty out some e-mails then grow larger, then deliver a few and grow larger. This seems to get resolved after I restart the Information store and all the messages will quickly get delivered out of the Local deliver folder. But after an hour or so the delivery will slow down again.
Does anyone have an idea of what might be causing this issue?
