SYMPTOMS

CAUSE

This problem may occur if an e-mail client tries to download an HTML e-mail message to a personal folder (.pst) file. When a message is converted from HTML to rich-text format (RTF) in a .pst file, the Store.exe process that runs on the Exchange server uses up to 100 percent of the CPU resources.
