Every time I reboot my computer and start Outlook 2016 for the first time, I get this error message. I've researched extensively to find the problem, but nothing I've done matters. The problem has been there since Day One of the installation. Outlook 2016 is the 32-bit version on a Windows 7 Professional 64-bit operating system. No other email client is installed on the system, including Thunderbird, which seems to cause problems. Suggestions? Thanks!
