Exchange Server Error Code Look-up

A Microsoft disponibilizou uma versão actualizada (v6.0.4011.0) da ferramenta Exchange Server Error Code Look-up.

Overview
Use the Error Code Lookup tool to determine error values from decimal and hexadecimal error codes in Microsoft Windows® operating systems. The tool can look up one or more values at a time. All values on the command line will be looked up in Exchange’s internal tables and presented to you. If available, informational data associated with the value or values will also be shown.
