Who says it isn't the norm? I've seen countless cases where people mail the same file to tens or even hundreds of people all the time. > The perf improvements that were achieved by cutting this feature ... I don't get why cutting SIS would be a performance gain. The system has to do I/O to lookup the blob no matter what. If the same blob is used for everybody, there's a better chance that the needed resources are already cached. If everybody has their own instance, the indexes are going to be much bigger, right? > Go in perfmon on your Exchange server and go under MSExchangeIS > Private/Public or MSExchange Mailbox/Public and add the Single Instance > Ratio counter to your perfmon. I bet it won’t be as high as you think it is. Ours reads roughly 5.6. So I'll have to buy roughly six times as much storage for Exchange 2010 vs the Exchange 2003 that we're running now. That will be fun, selling that to management. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
