Mails in Cc bouncing in Outlook Web.

[sureshramanujam]

Marking Cc to someone when composing a new mail is bouncing back. Also, Forwarding a received email to someone is also bouncing back. 

Did anyone face similar issue?

Seems to work just fine here. Check whether it's happening for specific addresses only. And if you can reliably reproduce the issue, best open a support case.
