When you "delete" a deleted message, it should toggle the flag. Undo delete works sometimes, but you can't easly go back and change the deleted flag on an arbitrary message easily.

It's working for me using dec11 commercial trunk build, win98. We do have a bunch of Undo bugs (not limited to IMAP delete model/"mark as deleted") which may be interfering. But the basic Undo with delete model works for me. Redo isn't working (I believe this is a general problem with several Undo bugs, but noticed it was particularly mentioned in bug 29039). I can delete/mark an undone message again using Delete on that same message, but not with a Redo.

Ok -- Ben was talking about using Delete button on a marked message. He was not referring to "undo" at all. Steps: 1. Using mark as deleted mode: Select a message and click Delete. Message marked for delete with X. (selection moves to next message) 2. Go back to the marked message, click Delete. X is not toggled.
