RollOut: Microsoft Exchange 2007 Beta 2: Page 5 of 6

Rather than try to take over the entire space, Microsoft is acting as a glue for partners. Exchange and Office Communicator will integrate into other UM systems, for example. We've seen Microsoft partner with other vendors such as Siemens, and we don't believe it's trying to conquer the market by force.

Time To Upgrade?

If you're running Exchange 5.5, you'll want the latest system; after
all, support for problems pertaining to that version ended at the end
of 2005 . Exchange 2003 users will be able to hold off for a bit,
unless you need the improved Web access or want to use the UM
features. Microsoft isn't supporting direct migration from 5.5 to
2007. You must migrate from 5.5 to Exchange 2003, and then again to
2007.

Although Microsoft is targeting its conventional
base of midsize to large enterprises with this release, it
will offer a customized version for smaller businesses.
Meanwhile, users with volume license discounts or site
licenses could get the upgrade for free as part of their
existing contracts.
