Hi @RonnieKapoor-4055 , certain characters such as "@" are restricted in Azure resources. You can find the full list here: https://docs.microsoft.com/en-us/azure/azure-resource-manager/management/resource-name-rules

User created restrictions are mainly to prevent profanity but Azure doesn't allow certain characters by default. Please let me know if you have any questions!

If this answer helped you please mark it as "Verified" so other users may reference it.

Thank you,
James

Hi @RonnieKapoor-4055 , the document above pertains to everything contained in the services. Since the sign up field falls under Azure AD, the same rules apply.

Best,
James
