Please consider fixing the Universal Acceptance issue in TEAMS. Registering to TEAMS with NewgTLD email addresses is not possible at this moment even in ASCII and with three characters in the Top Level Domain.
Here is the screenshot of the error. You may find the resources helpful on www.uasg.tech when fixing this issue.
We look forward to hearing from you about the progress of your Universal Acceptance effort on this issue.
