I have the problem that the STORE.exe takes all the momery of my machine. Physical RAM 512 MB. Store.exe takes 400 MB and more. If I restart the information store service everything looks fine. But the Store.exe starts again eating the memory. It happend with Win2k SP2 and Exch SP2. So I upgrated to Win2k SP3 and Exch SP3. It's the same again. What can I do ? What is wrong? Thanx. Ingo
