Installed Exchange 5.5, NT SP4, Exchange SP3. PentiumIII 550, 256M RAM. I set the Internet Mail Service to manual startup. Everything works great until I start the Internet Mail Service: then processor usage goes to 100% and stays there, ultimately bogging down the server until I have to reboot it. Memory usage and hard drive usage are not affected. No single processor thread is the culprit, but (using Task Manager)the STORE.exe is at 8000K or more. HELP!

have you run the exchange optimizer since you upgraded to sp3, sp3 makes some major changes and you need to run prefwiz.exe ( the optimizer)
hope this helps

I would not worry about excessive memory usage by Exchange 5.5. By design, Exchange 5.5 will use as much available RAM as possible, and will relinquish it should other processes need it. However, there are known problems with the information storeand other services even after sp3 (refer to support.microsoft.com, article Q248838). There are post-sp3 fixes available for download at www.microsoft.com/downloads/search.asp.

Do you have auto forwarding set up for any mailboxes?

If you do and one of the forward to addresses is misspelled, then a situation like the one you describe can occur.

Use the Exchange admin consol to track messags for any user that has the auto forwarding enabled. you will see hunreds of messages addressed to the user. Disable the auto forwarding until the address is corrected.
