Since my migration to Windows 7 there have still been a few things missing that would be nice to have. One of those is the Exchange System Manager tools. There are ways and methods out there to getting this to work but most will involve uninstalling outlook and reinstalling after you have installed ESM tools.
I have been waiting for the ESM tools for Exchange 2010 to hopefully work with Exchange 2003 but that hasn’t happened either. Although I did find a really quick and easy solution this morning after reading the following posts on TechNet (Exchange System Manager for exchange 2003)
You will need to download the Exchange System Manager for Windows Vista then use something like WinRAR to extract the contents.
You will also need to make sure you already have the RSAT tools installed (Remote Server Admin Tools)
Finally open up a Command Prompt as Administrator. Browse to the directory that contains the ESMVISTA.MSI file. Run the following:
Once this is done you should be able to open the “Active Directory and Computers” and edit an Exchange User with all the required email tabs.
