not necessairly, but the BES forum will have people that work with BES AND desktop manager and will be able to point you in the right direction.
I belive that when you setup DM for use with a BES account there is a box in DM from email settings? Is it possible that in there somewhere its set to HTML which is why when connected it syncs those settings?
