frequently get msg: "Lost connection to Evolution Exchange backend process"

Binary package hint: evolution

I did see another bug similar to this, but it had more of the message than mine does... file or folder not existing and I do not believe that is what is causing my problem...

At any rate, I frequently receive error messages when using evolution for exchange... If i close evolution and re-open it, the problem is usually fixed, until the next time it happens... i usually don't notice it happens until i notice that my folders haven't updated... I won't usually notice it hasn't updated unless I know for sure there should be a new email listed, but evolution isn't showing it to me (if i get an email on my blackberry, then I know i've received a new email)... I then usually look down to see the error message sitting in the status bar.

Sometimes, though, i'll notice the "connection to the back end process" is down when switching to a folder I haven't viewed in evolution before and it displays no emails (because evolution has never downloaded them before) and i notice it is not working on downloading them, but reporting the error to me.

Once the connection to the backend process is down, changing to any folder either gives the "error while refreshing folder...." because the process is down, or the "error while opening folder..." because the process is down (screen shots attached).

Again, closing and re-opening evolution always seems to fix this.
