Good day. 2 days ago I installed windows 10. I did not like it so i reverted back to windows 7. Not sure if that cause the problem I have now with windows live mail. It seems like some of the emails I have will not delete or disappear it always comes up saying that there is an error. I have uninstalled windows live essentials and downloaded it and installed it again. It is still doing the same thing. I have tried everything i can find I am hoping someone  can help resolve this issue!
