EDB Limit Changer
Windows Applications
Serivce Pack 2 for Exchange Server 2003 introduced some new configurable
settings for information store database limits. These limits used to be hard
coded depending on the version of Exchange you were using. Standard Edition was
capped at 16GB and Enterprise Edition was capped at 8TB (which is the largest an
Exchange Jet database can be). After applying SP2, administrators can now set
arbitrary limits to the sizes of their information stores. Standard Edition
users are still limited to one private and one public store, but can set both of
them to a maximum size of 75GB! It is not configured this way out of the box,
however!
To set a custom "hard" limit, you must modify the registry. The EDB Limit
Changer tool will do this for you. This is useful for both Standard and
Enterprise editions. Although Enterprise edition databases can be up to 8
TB in size, you may want to set this smaller. It is better for Exchange to
crash because it hits the registry's "hard" limit than the physical limitation
of your hard drive!
EDB Limit Changer requires the .Net Framework 1.1. For more information, see the blog post below!
