Yesterday I was having problems with Email loading, it was very slow. Sometimes it would load after the 3rd try. This morning at 5 AM it seemed ok, but the next login did the same as before. As I said, I have a new machine with 64 bit windows10 Home on it, It is a 2.9 ghz multi core with intel i5 . After setting up the new computer , Email worked great at first but has degraded to really bad. Also I have lost all my contacts. . After I sign in the white screen with the grey square appears saying it is loading, then the grey square disappears and just the white screen shows. No messages or notifications come up , Once this morning " Zimbra" appeared in the search. I have cleared History, rebooted, repowered,cleared cache,flushed dns as recommended but nothing seems to help.
