I have a program for scheduling and emailing jobs, I was emailing directly from this program through Thunderbird but as of today this is no longer happening. I was getting a message asking if this is what I wanted but this also no longer appears. I now get the following: Microsoft office Outlook Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft outlook and set as the default mail client This could be Windows but I don't believe it has updated. Thanks Glen
