Riposte solution
The mailbox was opened in read-only mode. This means you cannot make changes (like flagging or deleting messages) in the current session. Riposte will still fetch emails, but won't attempt modifications. No immediate fix needed; however, if you intended to modify messages, you may need to re-open the mailbox in read-write mode (Riposte manages this automatically when needed).
