Microsoft Exchange Online is a hosted enterprise messaging solution based on Microsoft Exchange Server 2007 and provides the following:
- Improved email security
- “From-anywhere” access to email for your employees
- Enhanced operational efficiency for your IT staff
- 5GB mailbox storage per standard licence, configurable up to 25GB per mailbox
and can co-exist alongside an on-site Exchange Server with Global Address Lists (GALs) in synchronization.
Exchange Online includes Exchange Hosted Services Filtering for Virus and Spam protection. It also includes Push Email for WinMo 6+ and ActiveSync 12 devices; while it will sync with Nokia e-series and iPhone 2.0 there is no Push Email.
Of course the big questions is, “Will it work with my CrackBlackberry?” and the answer is “Of course it will” 
Blackberry Internet Server (BIS) support is part of the standard cost and if you require full integration then Blackberry Enterprise Server (BES) can be added for an additional cost.
Pricing:
Exchange Online costs £6.69 per user per month, so £80.28 per user per year. After the November 2009 price cuts, it is now:
£3.35 per user per month, so £40.20 per user per year
Blackberry Support:
Blackberry Internet Server (BIS) support is included in the standard Exchange Online price.
Blackberry Enterprise Server (BES) support is an extra charge as follows:
Initial Setup = £33.47 for a minimum of 20 users so a total fee of £669.4
Ongoing Costs = £3.35 per user per month. This is on top of the Exchange cost thus £6.69 + £3.35, making a total of £10.04 per user per month.
