Exchange datastore, chapter whatever
as the Exchange „Jet” store is inherently unreliable, and most folks dont manage that well. They manage it by limiting user space to 150mb or below.
(The averages I see in Domino environments is *no limit*, 500mb, 150mb for temps. Largest single mail file - 12gb. Thats an entire exchange 2003 pre-sp1 data store).
For the slower ones, let me repeat it here: Notes can handle a single, 12 GB „mailfile”, which is more than ONE Exchange 2003 datastore could support pre SP1, without any problems.
If you take a look at Bill’s and Paul’s „Worst practices” presentation during Lotusphere 2006, you will see, that Domino can even handle a single mail the size of 2.145.397.995 bytes without crashing.
