I had the system drive on my Exchange server get full...I added a couple of drives and created a spanned volume and moved my data store and logs...no problems with any of that...the system seems to have arbitrarily imposed a 2M message size limit...I have checked everywhere and cannot find where to tell it everything is ok now, and stop imposing a limit...ESMTP does not show a SIZE limit, and neither does any other config value I can find...I think the system still thinks it's full...the virtual drive reports a HUGE size (which is literally multiples of the physical disk size of ANY of my drives)...yet all physical drives have Gs of free space...any ideas? (I've checked with some Exchange experts and no one has any ideas so far)
