Active Sync 2003 vs 2010

want to enable active sync and use a new proxy server I installed in our dmz to front-end it. I have enabled and used active sync under exchange 2007 not 2003.

I need to know if we use our 2003 will we have less security options then if we use the new 2010 exchange env? I would like remote wipe, password enforcement and encryption of the email at rest on the device. Please get a comparison of active sync 2003 vs 2010 together and send to me.

I can proxy the active sync from the dmz to either the 2003 or 2010. Of course we won't have any users on the 2010 but could perhaps move some over. The active sync will be for executives and AEs for iPad email

I hope I can answer part of this for you.

In 2003 SP2 came a new version of active sync (EAS) which intriduced alot of the features you are talking about like Mobile Device Security (remote wipe and password enforcement)
Other feature which was intruduced where Direct Push, Global Address List Lookup and Mobile Admin (which you need to install seperatly)

In E2007 came there security options reset pin/password from OWA2007 and enhanced PPS security.
Other features that came with 2007 are support for HTML messages, Fast message retrieval, follow-up flags, meeting attendee information, better exchange search, sharepoint support, autodiscovery and out of office from your mobile (you can manage it from mobile)

In E2010 its a long list of new and changed things but I found a nice site explaining most of it
http://blogs.technet.com/b/ucedsg/archive/2009/05/31/what-is-new-with-exchange-server-2010-activesync-and-outlook-mobile.aspx

I would recomend trying to have the newest EAS server (E2010) because of security, cooperation with more wendors and many other features and Exchange 2010 is made to support Exchange 2003 mailboxes throughn OWA and EAS so you will not have any issues here.

Hope this helps ;-)

Thanks.. I mainly need to know about at rest encryption,  password enforcement and remote wipe  with exchange 2003 as that is what we have now and would be the fastest to get up and running vs later when 2010 is in.. Is the email on the phone encrypted under Exchange 2003?

S/MIME email encryption comes with Exchange 2003 SP2 (EAS 2.5)
But Exchange 2007 SP1 allows device (mobile) encryption not only encryption on emails.
Other encryption that also shipped with 2007 sp1
Require encrypted S/MIME messages
Require encrypted S/MIME algorithm
Allow S/MIME encrypted algorithm negotiation

And in 2010 SP1 came Information Rights Management (IRM) over EAS (a method to apply digital rights management control and encryption to email messages that are sent and received).

Yes and I forgot that in Exchange 2007 (RTM) came encryption on storage cards (allows you to encrypt the storage card in the phone)

So yes 2010 SP1 is the best option ;-)

Have you got all the info you needed?

If not then what are you missing?
