I have the same problem. Just upgraded from Win 7 Pro by necessity because I couldn't last any longer without support. Now in Win 10 pro sorting through setup and have lost my ability to click email notifications that take me to my desktop Outlook which
is configured to my requirements. instead I am going to online Outlook which i DO NOT WANT.
I see nine pages of comments here with similar issues.
COME ON MICROSOFT - PROPOSE A SOLUTION! You're forcing this set-up on us and costing many of us wasted time in sorting through trivial, irritating, ill-functioning features.
