Exchange 2007's mobility capabilities much improved over Exchange 2003's

While Exchange 2007's features may not quite match those of Good Messaging Server, they are definitely adequate for most organizations.

Exchange 2007 provides a significant improvement in the mobile messaging capabilities that were found in Exchange 2003. I'll be the first to admit that I've gotten a little too used to carrying my e-mail on my hip! While Exchange 2007's features may not quite match those of Good Messaging Server, they are definitely adequate for most organizations. Exchange 2007 has a number of features that make it appealing to enterprise customers, including the following:

  • Administrator- or user-initiated remote device wipe: In Exchange 2007, as in Exchange 2003 SP2, an administrator can remotely initiate a device wipe or password reset. This is extraordinarily useful in the event that a device is stolen as sensitive information can be kept out of the wrong hands. In Exchange 2007, however, a user can initiate a device wipe from within Outlook Web Access. This is handy if a device is lost in the wee hours, when IT staff may not be available to initiate a wipe.
  • Enhanced security policies: In Exchange 2007, mobile security policies can be organized per-group and per-user. The security policies include requiring data encryption, deletion of data after a PIN is entered incorrectly too many times, limiting the size of attachments, and more.
  • Over-the-air search: A server-based mailbox can be searched from the local device and the results sent to the device. This means that a user can search a full inbox that includes months-old items, and get complete search results.
  • Unified messaging integration: A mobile device can also be synchronized with a user's unified messaging items so that voice mails and faxes can be received on the road.
  • There are a number of other improvements as well that are not discussed here, but these are the most significant and worthy of attention.
