Outlook 2007 installed on Windows 10
I can't get rid of the message "Either there is no default mail client....".
Outlook ran fine on win 7 but now installing it on win 10 I can't stop this message. I've spent days following web advice, setting Outlook as default, multiple registry changes, etc, etc and nothing works. It only comes up after a "send/receive"
Has anyone had this issue and really fixed it?
