Exchange Cached Mode Archiving Question

Hi Guys,

I am trying to find documented proof that supports the answer to the following scenario.

We are currently utilizing Cached Mode for outlook clients but are put into a scenario where we need to move everyone's data off of the server and into pst files locally on thier pc. These are hundreds of users most of which are behind bonded T1 connections.

My question is when instructing users to perform this action, does the mail move from the ost into the pst locally and then the client and server synchronize or does the traffic come from the server to the pst file? My concern is bandwidth utilization since many of the mailboxes are quite large.

AFAIK yes, this is what will happen and the Outlook will perform MAPI instructions to delete the messages from the server

Yes that the transaction happens locally?

Do you have any documented reference that supports that thought?

It seems you want to disconnect the outlook from the exchange server and use a local pst file, right?

Why not disconnect from the network, open the cached outlook profile and then export everything to pst. Then setup a new profile which uses the pst file.

When the above is done you can simply delete the mailbox on the server as all maildata is in the pst.

That's the easiest way in my opinion when you want to go from a cached exchange account  to a local pst with pop3 account.

Outlook in cache mode means your saving a Copy of your mailbox locally and in Sync with the Mailbox on server. Now if you move a set of emails or all data from the OST to PST .... it would be much issues on the network or server as it only a small sync message thats pushed from the Outlook to the server telling that this is the new update.

As i would say you can disconnect the Outlook or make it work offline meaning that it isnt connecting to the server and you can still move all data to PST and then simply connect it to Exchange server and let it sync.
