1) Do we need to purchase a BES in order to sychronize email to a users BB?
No. You can get BlackBerry Enterprise Server EXPRESS for free for up to 15 users. Go to: https://www.blackberry.com/express/?cp=ILC-BB1
You need to enter a unique PIN for each CAL.
2) Can we use BIS instead of BES to synchronize email to a users BB?
If your Exchange is accessible through OWA or set up for POP or IMAP access, sure, but you won't get sync on Contacts, Calendar, Notes, and Tasks, and may not get full sync on email either. OWA must be accessible from any computer running only IE - no VPN client or other non OWA authentication.
3) Will the synchronizing of email be immediate with BES and BIS?
BES is pretty close to immediate delivery of emails (I sometimes get email on my BB before it shows up in Outlook - in Connected uncached mode). Sync FROM the BB to Exchange is dependant on time and whether or not communications are initiated by BES/Exchange.
BIS polls every 15 minutes.
