SYMPTOMS
If a user performs a search of the contents in their mailbox folders from within Microsoft Outlook Web Access (OWA), the Exchange 2000 private information store log files in the Mdbdata folder grow more quickly than expected.

Each time the OWA user clicks the Next Page and Previous Page buttons in the Search dialog box to move through the search results, the log files grow larger.



CAUSE
This behavior is expected and occurs because the Exchange 2000 JET database engine is creating indexes and populating the search folders. The information store log files grow more quickly or slowly depending on the number of returned search results.

It is important to account for the potential growth of the information store log files when you determine the hard disk requirements for the Exchange 2000 computer.
