Outlook 2002 -- Operation Failed Error

[JD]

Hello,

When I hit the "Send/Receive" toolbar button I get
an "The operation failed. An object could not be found."
error message. When I navigate to and from the inbox the
messages are retrieved fine, including new ones.

I'm running Outlook SP2 on Win2K. Is a reinstall
necessary? Will that wipe out my settings?

Thanks in advance for any help...
