when mail items move back to the mailbox, do they get resent to the BB? also, does this happen when the mail is moved\deleted on the BB or just when it is moved\deleted in outlook? and what version of outlook are you running.
I really doubt that it has anything to do with the BB's but it is awfully coincidental that the people with problems all have 7250's...unless of course, all of your users have 7250's
