Registry Settings
Exchange wouldn't be Exchange without some registry settings that you can twiddle to change the way things work. Background maintenance has a selection for you to experiment with, if you like playing with fire. You should reset these values only if you have an extremely good reason to do so.
All the registry values are of the REG_DWORD type. They fit into three registry subkeys, as Table 2 shows, where PS indicates the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem subkey, M indicates a subkey for a mailbox store, and P indicates a subkey for a public store. In versions earlier than Exchange 2000, Microsoft placed all the general registry settings for the Store in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeISParametersSystem subkey, but because Exchange 2003 and Exchange 2000 support Store partitioning, we now have a subkey for each server with separate subkeys for each store under that server. Web Figure 4 shows the registry hierarchy and settings that govern how the Store deals with a public store on an Exchange 2003 server. . . .
