I can't believe this is how QB keeps responding. The answers are jokes, and none of them work.  They have shifted the blame to Parallels, Thunderbird, Outlook, and everything inbetween.  The fact that is a problem dating back at least 4 years with no fix, I cant wrap my brain around this.  Your support staff is a joke, your product is joke.  Fix the issue and stop blaming everyone else.  It's your problem not anyone elses. I want this fix and I am tired of spending hours on the line with support to do nothing.
