Review for Autoarchive by michaelp
Rated 2 out of 5 stars
Seems to work only on the main Inbox folder for an account. If you have sub folders under your Inbox, this extension will NOT auto archived those folders. My only complaint so far -- if it did this i would give 5 stars.
I'm working on a new version of the extension, which will work with any folders. I will publish it in January.
