Exchange 2010 - Link mailbox with another AD account.

Good Afternoon,

I am a domain administrator for my company, my AD account (nobuyoto) is causing an issue with one of our in-house systems.

My supervisor has instructed me to create a new account (nobu) for myself in AD and use that one instead.

Creating the new account in AD is no problem, what I am unsure on how to do is to connect my Exchange mailbox to the new account.

We are using:

Domain Controller: Windows Server 2008 R2
Exchange Server: Exchange 2010

Another thing to note is that my old account (nobuyoto) must not be disabled, as it will still be used for other purposes, just without a mailbox.

Kindly advise how I am able to link my mailbox with the new account (nobu).

Regards,
N
