Thanks for your feedback! Just a note to let you know that we’re building your suggestion now. We plan to increase availability to this feature as we continue improving the tech, and ensuring a smooth experience across Office 365 following the URL changes in SharePoint Online.Pekka Kilponen supported this idea ·Pekka Kilponen commented
We have bough a company who had sharepoint already and got information from Microsoft that its ok we could change the domain later on to our official name. However we still have to use old obsolete domain name obsolete.sharepoint.com because it cannot be changed. This is not good. Making a new sharepoint instance and copying all data to it is now too tedious operation. When this change will be possible?
