Not certain where to report this exactly but maybe that's one place to drop a line for CU2:
Setup.exe if executed in CLI mode still tells it is CU1 - if run in graphical mode it is saying CU2 though, minor glitch that can happen, no worries.

Have a shared mailbox with "MessageCopyForSentAsEnabled" enabled, and permit the right to send as throguh a group.

However if the user is given the right directly as user object, things work as expected.
