This app clearly has headers saying that it was developed locally, in WA state, but the original firm/programmer can't be found. It's not a bad app, especially for a first effort. It just needs updating. BTW, I underestimated the number of PRGs in the calendar--there are 60 of them! I've started stripping out some of the unnecessary code--support for languages other than English, demo version, etc. to see if what's left makes any sense...

I don't know about Exchange server but I'll ask...
