Using Classic Outlook on Windows for personal email, calendar, and contact management
I am having this same issue. And can't send emails without the older version being open. There is no way to uninstall or change the program using Microsoft Enterprise Suite. I have tried to do an online repair, but that isn't working either. I would like to keep using the "new" version, it's nice looking and I can add other accounts to this version, but having both versions is confusing my computer.
Please come with an solution for those of us with enterprise suite.
