How to Reset User Mailbox Password in Exchange Server 2010

Summary: Outlook users can change their password through the Outlook app. But if they forget or lost their password, Exchange administrators can reset the Outlook users’ password through Active Directory (AD) server or Exchange Admin Center (EAC). This article describes steps to change or reset Outlook users’ mailbox password in Exchange server 2010.

Apart from the services, an administrator also takes care of MS Outlook mailbox management tasks, such as resetting Outlook users or Exchange password, and other related functions.

The Exchange Administrator should have valid login credentials of Active Directory (AD) or Exchange server to manage the mailbox management tasks, such as resetting Outlook password. An admin can reset MS Outlook users’ mailbox password by logging into the Windows or Exchange server.

However, if the administrator forgot or lost Exchange or Windows server password, you can use Stellar Toolkit for Exchange to reset the server password and get back access to the server without dealing with manual methods as they require technical expertise and often fail.
