Will doing a typical > rebuild on a routine basis actually harm anything? Just curious. I don't know everything there is to know about it. I know this much: 1) No preventative value 2) Typical rebuild compacts (i.e. gets blocks on your hard disk which have been "deleted". i.e. marked as "allowed to be overwritten by new data") defined as outside of the database file instead of inside it, so that other programs on your computer can use those blocks. 3) I _think_ that a typical rebuild moves data from one physical location to another, rather like a defragmenter might. So it can fix minor problems to do with fragmenting of files, like bad ordering of groups of messages in folders. It must do a few other minor things too. 4) Constant rebuilding (like every few days) is not good for your disk, and doesn't help anything if nothing's wrong. 5) The sort of problem requiring an Advanced Rebuild (screwed-up linking of data within the database0 is not a result of not fixing things that can be fixed by a Typical rebuild. It's a whole different order of problem, with a multitude of different causes unrelated to block fragmentation for the most part. (For all I know, there may be _some_ problems which are not that dissimilar, but most are.) So doing Typical Rebuilds which aren't necessary don't help, and in the long run might even hurt. And they don't prevent problems which lead to needing an Advanced Rebuild. If an MS person who actually works on databases is prepared to give out more information (doubtful), you might find out more. But this has been _their_ counsel all along, here, at MacTopia, and to beta testers. I assume they know what they're talking about. I'm only repeating what the developers have told us when I say the doing frequent unnecessary rebuilds is not preventative and might do harm. If you think you know more than the makers of Entourage, it's your risk. Sorry I don't have more hard information. -- Paul Berkowitz -- To unsubscribe: <mailto:[EMAIL PROTECTED]> archives: <http://www.mail-archive.com/entourage-talk%40lists.letterrip.com/> old-archive: <http://www.mail-archive.com/entourage-talk%40lists.boingo.com/>
