no, apparently not. yes a re-install is a good place to start.
I think I've heard others having issues with that app and email, but I believe that was due to m$ making some server changes.

I don't use it, but if you want to re-install the rom (o/s for ppc called windows mobile 5,6,6.1) you do need to backup all your contacts, ect.. as everything will be wiped out.
I believe your phone is a titan (sprint=mogul, verizon=something dumb...) so I would search those threads for others using telus.
