No this isn't a reference to my home life and the fact the refuse is collected today.
I've been running an experiment. Since my move to Exchange 2007 I've had a bigger mailbox, so I tried not emptying my deleted items folder to see how long it would take before the new mailbox filled up. This morning I signed into OWA at home to check my calendar and got the message that my mailbox was nearly full. Nice attention-getter, and a much better mail from the server. With so many items arriving by RSS a large proportion of the mail in my deleted Items never gets marked as read ... but I was surprised the counter got past 6000.
