Outlook web UTF-8 charset
Outlook Web sends emails in my organization using the ISO-8859-1 character set. However, Copilot claims: "Outlook Web (Outlook on the Web, OWA) does not generate your messages in ISO-8859-1. It always uses UTF-8."
My Outlook Web only switches to the UTF-8 character set if the email contains Unicode characters that cannot be displayed in ISO-8859-1.
How can I enforce UTF-8 globally for my organization?

Outlook on the Web (OWA) exhibits a nuanced behavior in its handling of character encoding. By default, messages are generated using ISO-8859-1, with a transition to UTF-8 only when Unicode characters outside the ISO-8859-1 range are present. At present, Microsoft does not provide administrators with a global configuration option to enforce UTF-8 encoding across all messages in Exchange Online (Office 365). The encoding process is managed automatically by the service and cannot be overridden through administrative settings.
