Hello, I have an issue. When IS Maintenance runs on my Exchange server 5.5 sp4 the store.exe process will use 90-100% of the CPU and will stay that way until I either reboot or stop/restart the Information Store service (which I have to use a 3rd party kill utility). I have found the following article at MS: http://support.microsoft.com/default.aspx?scid=kb;EN-US;q159297 This specifies that the solution is for version 4.0. Has anyone run into this problem? Any ideas? If I do as this article says will I lose everyone's emails that are on the server? Thanks in advance for your help. (this is my first time posting so take it easy on me!)
