Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Pernild,
Thanks for your clarification, as I mentioned previously, if we set up Teams for free for our own organization with Microsoft account, there should be an Edit profile option, generally, we can choose Edit profile to change the name we'd like to use from Teams web page directly > Save > Close.
Since we can't see the screenshot you provided. If you are in different situation, could you please upload the screenshot of your Teams profile by clicking Insert image icon as below?
Regards,
Bryan
