How to Restore Exchange 2010 Mailbox to Different Mailbox

Exchange Server, Video Tutorials

Exchange 2010 no longer has the notion of Storage Groups, which were used in Exchange 2007 and 2003 to contain logical groupings of databases. Exchange 2010 now simply lets you create databases on mailbox servers. The difference is that in Exchange 2003/2007, you created a Recover Storage Group (RSG) to restore the database into. In Exchange 2010, you simply restore the database and connect to it as a Recovery Database (RDB). First, you have to have a good backup that contains the item to be recovered. Windows Server 2008 and Windows Server 2008 R2 have the built-in Windows Server Backup feature. I cover how to use Windows Server Backup to backup Exchange in this article. Without the ability to restore an individual mailbox, it is necessary to first restore an entire…

How to Configure Windows 2008 Fine-Grained Password Policy

Video Tutorials, Windows Server

In previous versions of Active Directory, we had only one password policy for the entire domain. Some companies had to use multiple domains to place different password policies on different users or buy third party solutions. In Windows Server 2008, you can use fine-grained password policies to specify multiple password policies and apply different password restrictions and account lockout policies to different sets of users within a single domain. Password polices are designed to control what kind of password a user can have and how often the user needs to change it. Strong password policies are important to help protect your system and data.
