Sometimes when you try to create a new organization in Azure DevOps, you might encounter an error similar to the one shown below. The error might state “The given organization name is already taken, Choose a different name to continue”. The error is displayed when someone has already registered an Azure DevOps organization with the same name!
There is nothing we can do to resolve this and Microsoft also has no control over the Org names as copyright claims can be filed against the Org names within Azure DevOps as it’s something very internal. At best you can come up with a new name that nearly similar to your company name! For example if it’s “SpaceX” then SpaceXDevOps would be a good name for your Azure DevOps Organization!
