In our environment we don't use roaming profiles.
So I wonder if we can configure Exchange cache mode and configure users  OST file to be saved in the network, instead of inside  their local profile.

Thanks

Hi

This isn't recomended by Microsoft

http://support.microsoft.com/kb/297019

Basically half way down the page underneath Other behaviors of .pst files over WAN and LAN links: -

Because of these behaviors, Offline Folders (.ost) files and Personal Address Book (.pab) files on a network share that are accessed remotely are also unsupported configurations.

So to answer your question yes it is possible however I wouldn't do it

it a security concern:
let s say someone gets hold of an ost file and put it in a flash drive,
and build an exchange server with same name and organization name as the one in production and create a mailbox with the same name as the one related to the ost file, will this user be able to view the emails?

or may be there is a way he can convert ost to pst and view the emails?

What do you need OST files at all for? You only need them if the users don't always have an internet or LAN connection and therefore for that reason can't connect to your exchange server. I would disable cache mode as the mailbox is located on the exchange server anyway. If your exchange server is so unreliable that you can't always connect, then you have a more important problem to solve than enabling cache mode.

I would only use for notebooks which are used outside the company, and then it wouldn't make any sense anyway to have the OST on a server share.

I agree - if it's a security concern, DON'T USE THEM.  Otherwise, your scenario wouldn't work because the GUIDs on the accounts would be different... BUT, someone could easily get a tool to convert the OST to PST and open it that way.  So again, if security is the concern, don't use OST files except on systems that are encrypted to begin with.

Outlook2003 and earlier , I believe don't support encryption.
Outlook 2007 and later do. I am not sure if it is a strong encryption or not,

I was thinking FULL DISK encryption on a laptop.

If you don't use OST files you won't have a security concern and you won't have crappy performance by putting them (or .PST) on the network, though laptop users won't be able to use Outlook offline.  If you are so concerned about security then disable all access to the Exchange server for client protocols and use Outlook Web Access only.
