The other day I was looking for a way to bulk modify the attributes MsExhQueryBaseDN and extensionAttribute15 in Active Directory. Modifying these attributes manually one by one on hundreds of users is impractical and is error prone.

So to automate the process, we would have to create a script or use a tool that can automate the job. Creating a script can get complicated. Personally I like scripting as I can always reuse the script for something else later on. However in this case I needed a quick and simple solution as I didn’t really have time to write the script. One tool that I’ve come across in the past is ADModify.

This tool allows me to quickly target the objects in AD that I’d like to modify and modifies it for me.
