Just setup a second Thunderbird profile for Exchange. Using Owl for Exchange plugin. I right click onto a subfolder, and pick Properties, then go into Synchronization. I click onto a checkbox for "Select this folder for offline use" and I hit OK to close the window. Nothing happens. I go back, and the checkbox is not checked. I tried hitting the Download Now buttons, nothing happened. Any clue why my check box selection is not accepted? When I used Outlook, I set it up to use OST, so I have a copy of my email that is on the remote Exchange server. Now I am trying to do the same with Thunderbird. Thank you
