Make it easier to update a business name and associated URL's
I had setup a small business account with Office 365 and have undergone rebranding. Trying to be able to change default accounts, domains and the previously setup URL's for sharepoint and the <companyname>.onmicrosoft.com. proved too awkward for me. I have simply decided to export all my data out of O365 and will decide whether it's better to start from scratch or use a different product suite altogether.
