Anyone out there?
Same problem arose on a second Windows laptop. While doing a system restore on my machine worked to solve the problem (not sure what got uninstalled), the same cannot be said for the other machine. And, today, my machine has just shown the problem again. I can't see that Windows has installed any updates today so am at a loss.
The only saving grace, well, partial saving grace, is that you can still set-up Outlook using IMAP but hardly a longterm option...
