Using the standard edition of Exchange 2000, if you split mailboxes into different groups, how does this affect the 16GB information store limit? Does the limit include all mailboxes, or will each group have its own 16GB limit?
The Standard Edition of Exchange 2000 does not support multiple storage groups or multiple mail stores/public folder stores. You can only create one storage group and only one mailbox store and one public folder store per server. In this case, each individual database is limited in size to 16GB (e.g., 16GB mail store and 16GB public folder store).
If you upgrade to the Enterprise Edition, you can then create additional stores and storage groups, and none of them have a size limit.
