Does not seem to be Compatible with Gmail Rated 3 out of 5 stars
My rating would go from 3 - 5 if it worked with Gmail. When it was only accessing our imap accounts, it worked great. It does not override your copies settings so you have to make sure they are set up to work in conjunction with the add-on.
Unfortunately, our company is moving to gmail and it does not seem to work with the labels to folders and the fact that everything is really in all mail. I have tried several different settings and none of them seem to work.
