Exchange password reset issue on Archos101, K9 OK for mail. calendar alternative?

[Brett Steingo]

A few forums mention the problem with the archos 101 - once you have setup your exchange password you can't change it. So routine changes from your company become a problem. Only suggestions I have seen are to reload the entire account or use K9 mail. So K9 works, but doesn't have a calendar. So password resets still prevent calendar syncs. Seems like a really silly problem from Archos but what is the solution ?

PS. some have suggested Nitrodesk Touchdown. I can't justify the price just to get around this password reset issue. Archos: please fix!
