Windows Mail 2011 is noted for doing this and all inquiries have met with the "we will fix it with the next release". Well, it has been almost a year now and no fix. I use Outlook now and some things don't work as well with it - like trying to "send" a document. It will not "send" until you open the Outlook program. So, when I am doing schedules, etc. with Front Page, I have to remember to go and open the Outlook program before it will actually send. I have also found that when using the "Outlook Connector", Windows will not shut down properly. I cannot therefore, use the calendar updates I have done in Mail. Funny, the old Windows Mail program worked fine and now they have "fixed" it so it will not run and updates itself to Windows Mail 2011, which is a complete failure.
