I have WLM on Win10 that's been working fine but suddenly I keep getting a window that asks me for my password. I put it in and it goes away for a few minutes then pops up again. If I hit cancel the window just goes away but also comes back a bit later. All the while my email comes in and goes out anyway. Then a large window will come up saying email cannot be sent or received but it does it anyway. It's really annoying. Any solutions?
