The logs indicated that the undo operation was working fine but the other stuff was a little concerning until I realized you were talking about the special gmail starred folder.

The situation is basically this:

- We remove the stars from the messages.  gmail *immediately* expunges the messages so they are no longer present in the folder.  gmail has a per-user IMAP implementation setting (accessible from the web UI, not IMAP) that lets the user indicate whether messages should be expunged immediately or not, which I believe defaults to immediate.  Which is why we're seeing this.  We don't realize the messages went away.

- We go to perform the 'undo' operation and it appears to succeed to us, possibly because we're using +FLAGS.SILENT.  Because we didn't realize that the messages were already expunged, we assume the messages are still there and present them as such.

- During the refresh we realize the messages are gone.


No matter how we address this, this is a somewhat tricky one.  In order of increasing user-friendliness and increasing complexity we could:

- Disable the 'undo' option in known "smart folder" situations keyed on the type of smart folder.  (We do understand what the 'starred' folder is.)

- Maybe not use SILENT to detect deltas directly, etc.

- Just be better about automatically synchronizing when we see the "* N expunged" message and then using gmail's CONDSTORE support to bring ourselves up-to-date quickly.

- Have specialized gmail support to track the unique message id for the message and to understand that we can re-apply the change in the all mail folder.

Unstarring messages from the starred folder accidentally and being unable to fix it does seem fairly annoying, so the last one would probably be most ideal.  It also need not be entirely gmail specific...
