When I first got my Sprint Treo 650, I was able to receive a meeting invitation from Outlook and automatically insert the meeting into my Calendar by simply opening the attached Meeting.ics attachment. After a few weeks this stopped working. I now see an error message saying I don't have an ics viewer. I don't know what happened to break this useful feature. More importantly, I don't know how to fix it! Any suggestions? Sprint's help desk told me to reinstall everything from the original CD. I did this, and had to reinstall the upgrades and EVERYTHING else, and it still didn't help.
