I believe the server does it automatically - someone from ATS can correct me if I'm wrong, but I've noticed that in my account and assumed that was how it operated. ---- Jack Kramer Computer Systems Specialist University Relations, Michigan State University 517-884-1231 ________________________________ From: Peter J Murray <[log in to unmask]> Reply-To: Peter J Murray <[log in to unmask]> Date: Thu, 14 Aug 2008 17:03:58 -0400 To: <[log in to unmask]> Subject: [MSUNAG] sent folder in mail.msu.edu Hello I've been seeing a strange issue with Thunderbird IMAP in combination with MSU Mail. Their Sent messages are split into folders by month, without the user doing anything. I can't find an option in Thunderbird or mail.msu.edu that would explain it, and this is happened to two people so far. One day all their Sent messages where in one folder, and the next day, they had moved into folders according to month underneath the Sent folder. Any ideas?
