I would say to talk with your IT person at work. It sounds like to me that you are having problems gaining access. Where I work they have the Microsoft Exchange server locked down like the US Mint. I couldn't get the bb on it and I don't even want to bother trying putting the droid on. Maybe they changed security settings after you got the phone?
It might be different for him since he works for the Government. Don't know why since it seems all the secret information we have is being leaked anyway.
OP going from a Blackberry to a Droid is a learning experience. But technology wise, mail aside, there simply is no comparison of a Blackberry to a Droid. Blackberry is 20th century. Android is 21st Century.
Still I understand that mail can be an issue.
I agree, BB in my opinion handles email so much better than droid does. but the droid does everything else SOOOO much better it isnt funny. (then throw in the huge screen) I ended up using exchange and that got me closer to the BB for email but its still not the same. But i have to root to get copy/paste (which works great) but as said earlier, the longer you have a droid, the better it gets.....
