Okay, so I have a server that's a little RAM hungry.  Is there any way to administratively limit the RAM that the Exchange 2000 info store will use?  

Thanks a bunch.

I wanted to do this too, but read on a ng somewhere that store.exe only takes RAM that is not being used, and hands it back if it's needed by another process.

I found the answer myself, in a news group.  Quite a chore it was to find this info:

Store.exe is supposed to take as much memory as possible - this is by
design. It's called dynamic memory allocation. It should release the memory
when it doesn't need it. You can combat this by tuning store.exe as
mentioned here (URL will wrap):

From the article:
Steps to Modify msExchESEParamCacheSizeMax
This procedure relies on the use of the ADSI Edit tool, which is included
with Windows 2000 Support Tools.

  1.. To start ADSI Edit, click Start, point to Programs, point to Windows
2000 Support Tools, point to Tools, and then select ADSI Edit.
  2.. Expand the Configuration Container Naming Context of your Active
Directory.
  3.. Navigate to the following path: Configuration Container |
CN=Configuration, CN=Services, CN=Microsoft Exchange, CN=<organization>,
CN=Administrative Groups, CN=<Admin Group>, CN=Servers, CN=<server>,
CN=InformationStore
  4.. Right-click the Information Store object and then select Properties.
  5.. Select Both from the Select which properties to view drop-down list.
  6.. Select the msExchESEParamCacheSizeMax attribute and adjust the value.
Although no value will be present, the default will be 230400 (which is 900
MB). The recommended maximum for this value is 307200 (which is 1200 MB).
  Note Be careful when setting this value, because it is very easy to make a
mistake and set the msExchESEParamCacheSizeMin attribute instead.

  7.. Click Set after changing the Edit Attribute field for the attribute
and then click OK.
  8.. Close the ADSI Edit tool by closing the MMC console application.
  9.. Wait for Active Directory replication to replicate this new value
throughout the forest. This should normally be complete after three hours.
  10.. Restart the Microsoft Exchange Information Store service on the
Exchange 2000 computer.
