With Exchange 2010 out, and power users hungry to take advantage of it’s new features it’s a sad thing indeed to think how long it’ll really take for your workplace to upgrade. Anyone with any IT exposure knows just about how long it takes for changes to make it to production. Especially if it ain’t broke. Nobody in IT is going to volunteer to fix it. So you’ve heard some talk about upgrading to Exchange 2010, but that it requires an upgrade to BES 5.0.. and to do both they can’t schedule it for another six months.. eeegads.

Messaging Guru Sembee has posted successful results of a Blackberry Enterprise Server 4.1/ Blackberry Professional Server 4.1 implementation with Exchange 2010. Continue reading for more details.
Testing done is as follows. Though it might not be enough to woo your IT department it might just be enough to get them thinking. If you can’t have BES 5.0, at least you can have Exchange 2010, a Blackberry 5.0 OS and a 4.1 BES…

- Full over the air Enterprise activation.
- Sending and receiving email from the device.
