There may be times when you need to add tens or even hundreds of domains to an Office 365 tenant so using the GUI isn’t really an option.

I’ve created a little script here that will make this process easier.

It takes a csv file (called domains.csv) that exists in the same folder as the script itself and outputs the domain proof required for each domain to a domains.log text file.

 

The CSV file must be a single column csv file in the following format;

Domain
domain1.co.uk
domain2.co.uk

I’ve included a generic domain CSV file in the downloadable zip archive if that’s easier for you.

logwrite “$domainrecord,$txtrecord”
}
