SYMPTOMS

You are using Outlook Web Access in a Microsoft Exchange Server 2007 environment. When you use the Italian version of the spelling checker to review a message, you may receive the following error message:

Outlook Web Access encountered an unexpected error and was unable to handle your request.

Additionally, the entire error report is shown as follows:
