Lost mail folders
I have recently changed internet providers and because of this i have lost a significant number of my mail folders I've organised emails into. Some come up, but only with half the emails i have saved. Others are not coming up at all, and i now see random folders I've never made. When i search for these missing folders in the search panel some show up but i can't access them.
Please Help!!!
