Problema:
All’avvio Microsoft Outlook 2007 continua a chiedere la password per poter connettersi ad Exchange Server 2007.
Soluzione:
Installare, tramite Microsoft Update, l’update rollup 9 for Exchange 2007 SP1. 
PS: Se Exchange 2007 gira sotto Small Business Server 2008 basta procedere all’approvazione per l’installazione dell’update rollup 9 for Exchange 2007 SP1 dalla console degli aggiornamenti.

Status: offline This is a very common question in the last month for SBS 2008 users. It is resolved by approving rollup 9 for Exchange 2007 in Updates.
Another option would be to install Exchange 2007 Sp2 as the wrapper for installation on SBS 2008 is now available.
