Company name change and email addresses

My company changed its name a couple weeks ago and so I needed to add a new primary address for those who had the old domain as a primary, and move the old primary to a secondary. I was surprised that I couldn’t hardly find any existing scripts to accommodate such an endeavor so I had to resort to doing it myself.

This script goes through all accounts in a given AD domain and whose primary email address is the "old" SMTP domain name, makes the primary a secondary, takes the username portion of the address and appends the new domain and makes it the new primary. I log all of the old address and new addresses to the screen, so redirect the output to a file to capture that. It doesn’t check for preexisting addresses so conflicts can occur. I had previously done my own extract to look for those, so dealing with them manually was easier and faster than coding for that.

I modified the script each time I ran it to change the AD domain I wanted to search (though I could have just defined an array of domain names and looped through each of them), and ran it against DLs and public folders, too, adjusting the filter to return the different object types. You will need to do the same.

Download the code here, or copy below.
