This is a pretty thick document for being a simple comparison of two e-mail solutions. The fact
of the matter is, this is not a simple comparison. A single page feature grid just can’t tell the
story of the similarities and the differences between the BlackBerry and Windows Mobile e-mail
solutions. To fully appreciate each solution, you will need to understand the comparison
presented here. By the end of the document, you should recognize that both solutions have their
strengths and weaknesses, and that both solutions are great solutions for right customers.

This comparison is based on the assumption that the customer has already deployed Microsoft
Exchange 2003, Service Pack 2. This is required in order for Windows Mobile 5 to perform as it
is outlined in the comparisons. For the sake of comparison; Exchange will always refer to
Exchange 2003, Service Pack 2, Windows Mobile will always refer to Windows Mobile 5,
BlackBerry will always refer to a handheld with 4.0 or later operating system. BlackBerry
Enterprise Server, or BES, will always refer to BES 4.0 or later.


Windows Mobile 5

If the customer has already deployed Microsoft Exchange 2003, Service Pack 2, no additional
hardware or software is required in the server environment. This means that there will be no
expenses for an additional server, server software, solution software, or installation services.
This does not mean that there are no server side costs to the Windows Mobile 5 solution. If the
company out-sources its server support, there is a chance that they may need to pay someone to
configure the server properly for this solution. And, while this solution is part of the overall
Microsoft Exchange environment, adding functionality to the system can lead to additional costs
of maintaining and administering the added functionality. The truth is that this impact will be
dependent on the size of the deployment. Adding a lot of wireless users will require more
administration than adding just a few.

Windows Mobile provides tools for creating and editing Word, Excel, text, graphics and audio
files. These files can be received or sent as an e-mail attachment. You can actually send or
receive any file format, even if you can’t view or edit it.


The BlackBerry solution requires that the BlackBerry Enterprise Server (BES) be installed on a
separate server from the Exchange server. While some customers will need to purchase an
additional server and server software, others will be able to install the BES on one of their
existing servers (Terminal Services, file server, SQL server, etc.). It is important to recognize
that a new server and the BES software are going to require some learning curve as well as
ongoing administrative resources. While the investment in hardware, software and
administrative resources can be significant, the security and control capabilities of the BES often
justify the expense. It should also be noted that there are BES flavors for Lotus Domino and
Novell GroupWise environments as well. This is an important factor for customers who may
have already deployed one of these e-mail solutions. Through the sake of this comparison we
will restrict our focus to the Microsoft Exchange 2003, SP2 environment.
BlackBerries can view several attachment types, but cannot edit attachments or create
attachments for sending.


If the customer has deployed Microsoft Exchange 2003, Service Pack 2, they can save a lot of
money by going with a Windows Mobile 5 solution. They will also have a lot better e-mail
attachment experience. If the customer has deployed Lotus Domino or Novell GroupWise, they
should consider a BlackBerry solution first. The customer should also consider the BlackBerry
solution first if security is more than just a passing concern.


Windows Mobile 5

By default, Windows Mobile 5, in conjunction with the Exchange Server, uses Username and
Password credentials for access authentication. These measures can be strengthened with root
certificates that not only authenticate the user’s access to Exchange, but are also applied to each
and every message transferred between the handheld and the server.

Microsoft uses SSL encryption to protect all content being transferred between the handheld and
the server. The Messaging and Security Feature Pack (MSFP) adds the option of S/MIME
support. This brings a popular feature of desktop e-mail security to the handheld.

Microsoft offers several methods to protect information that resides on the handheld. Users can
set password protection on the handheld that will require the user to enter a password when they
want to access programs and information. The MSFP gives Exchange administrators the power
to wirelessly manage handheld passwords as well as several other IT policies. Exchange
administrators will also have the power to “remote wipe” the handheld if the user reports it lost
or stolen.


Security is the hallmark of the BlackBerry solution. Where Microsoft transports your important
information in an armored car with armed guards, Research In Motion transports your
information in a tank, escorted by the Army’s First Armored Division. Both security solutions
will be more than adequate for most customers. Where security is more than just a concern, but
a deciding factor, the following BlackBerry information should be considered.

Where Microsoft uses Username and Password credentials to authenticate a user, RIM uses a
secure key and handheld PIN number for authentication. Like Windows Mobile, the BlackBerry
will also allow for root certificates to strengthen its authentication.
Where Microsoft uses 128 bit SSL encryption to secure your information between the handheld
and the server, RIM uses either 164 bit 3DES for older handhelds or 256 bit AES for newer
handhelds. RIM also supports S/MIME security for enterprises that require it.

The BlackBerry can be password protected, just like a Windows Mobile handheld, but the most
recent BlackBerries can also encrypt the information as it sits on your handheld.

The biggest differentiator between the BlackBerry and Windows Mobile security solution lies in
the control placed in the administrator’s hands. BES administrators are not only able to wipe the
information off of the handheld, they can also remove the operating system. This means that
even though the information is wiped from a Windows Mobile handheld, the handheld is still as
usable as if the thief took it off of the store shelf. The BlackBerry solution gives administrators
the tools to render the handheld completely useless to anyone who may recover it. BES
administrators do have quite a few policies that they can choose to administer. In fact, the
BlackBerry IT Policy Reference Guide contains over 200 policy rules that can be administered
wirelessly. Of those, almost half are security specific.


The majority of customers are going to be well served by the security features of both solutions.
If security is a hot button issue, the customer should look at the security aspects of the
BlackBerry solution.


Windows Mobile 5

Windows Mobile 5 allows for wireless synchronization of E-Mail, Calendar, Contacts, and Tasks
to the Exchange Server. These applications can also be synced to a PC, along with Notes,
Favorites, Files and Media, using an application called ActiveSync. ActiveSync is found on one
of the CDs that come with the handheld. E-Mail, Calendar, Contacts, Tasks and Notes can only
be synced to Exchange or Outlook. Favorites are only synced with Internet Explorer. Other
synchronization pairings are available with 3 rd party applications.


The BlackBerry allows for wireless synchronization of E-Mail, Calendar, Contacts, Tasks, and
Memos with the Exchange Server. When connected to the PC, the BlackBerry can sync with
Outlook, Outlook Express, ACT!, Lotus Notes, GroupWise, Lotus Organizer, ASCII, and
Netscape. PC synchronization is handled by BlackBerry Desktop Manager which is found on
the CD accompanying the BlackBerry. Password Keeper, Saved Messages, and other features of
the BlackBerry are not “synchronized” per se, but they are backed up onto the server. If the user
loses their handheld, these features will be restored when a new handheld is activated on the

Again, both products are going to serve the customer well. BlackBerry adds a few more personal
information management (PIM) applications that it is compatible with. If you customer is using
something other than Outlook, and it is listed above, this may be a deciding factor.


Windows Mobile 5

There are several different formats to Windows Mobile 5 devices on the market. Here are just a
few distinct models.

Pocket PC Phones – These handhelds include Pocket Outlook for E-Mail, Calendar, Contacts,
Tasks, and Memos; Word Mobile; Excel Mobile; PowerPoint Mobile; ClearVue (PDF viewer);
Windows Media Player; Internet Explorer and Terminal Services Client. Manufacturers and
carriers may also add applications on the handheld or an accompanying CD.

These handhelds will have a touch sensitive screen with a stylus. Other features that are optional
to the design include an integrated QWERTY keyboard, camera, speakerphone, WiFi, Bluetooth
and a memory card slot, just to name a few.

Smartphones – These handhelds include Pocket Outlook for E-Mail, Calendar, Contacts, Tasks,
and Memos; ClearVue (Word, Excel, and PDF viewer); Windows Media Player; Internet
Explorer and Terminal Services Client. Manufacturers and carriers may also add applications on
the handheld or an accompanying CD.
These handhelds are usually smaller than the Pocket PC Phones and will have a “joystick”
instead of a touch sensitive screen with a stylus. Other features that are optional to the design
include a camera, speakerphone, WiFi, Bluetooth, and a memory card slot, just to name a few.

While several companies are licensed to manufacture handhelds with the BlackBerry operating
system, Research In Motion (RIM) is the only manufacturer who’s handhelds are available in the
United States as I write this. While RIM has several models to choose from, they mainly fall
into two categories; Handhelds and Business Phones. All BlackBerries include the following
applications; Messages, Address Book, Calendar, Tasks, MemoPad, and BlackBerry Browser.

BlackBerry Handhelds – These handhelds have a full QWERTY keypad and a trackwheel for
interacting with the device. While all current handhelds include Bluetooth, some units also
include speakerphone, GPS, or even WiFi.

BlackBerry Business Phone – The Business Phones (7100 series) are more “phone-like” in size
and feel. These handhelds have a SureType QWERTY keypad and a trackwheel for interacting
with the device. The keyboard is laid out in a QWERTY organization, but has 2 letters to a key.
While all Business Phones include Bluetooth and speakerphone, some also include GPS or
broadband modem capability. The BlackBerry Pearl is unique in that it also includes a camera,
media player and memory card slot.

From a functional standpoint, Windows Mobile 5 handhelds tend to be much more robust as
features go. Media Player can be used for MP3s, but it can also be used to show video
testimonials, product demonstrations, and even listen to business audio books. A camera can be
used to take party pictures, but it can also be used to record images of damaged packages,
completed installations, and even parking lot signage so you can find your car at the airport. The
additional features of the Windows Mobile devices may be frivolous to some, but they can be
important business tools to others.
