No, you're looking at one or the other. Think of the OST as a good thing. If the system goes down and nothing can be recovered, the users simply logs into a new system and they've lost very little (stuff that was stored on the bad system - nick names etc). OST = Good in this case.

I know not best practice but for the Linux mail system it was required. I would guess then that I need to talk to the Exchange admin and find out the ground rules I will be living under now. Can OST and PST files live on the same system? Be open at the same time?

When using cached mode, everything is stored in an OST file, rather than a PST file. I'm not sure I would recommend moving mail to a separate PST file. A PST file exists in a single location, and if there's a failure (e.g. disk fails, or laptop gets stolen) then you lose the mail. When using cached mode, everything (except offline edits) is stored on the Exchange server.

Then I would need to have all my mobile clients use cached mode if possible or make sure they move their mail to other folders in their Outlook profile correct?

Everything will sync when Outlook is reconnected to Exchange. Cheers Ken From: Jon Harris [mailto:[EMAIL PROTECTED] Sent: Wednesday, 27 February 2008 10:18 PM To: NT System Admin Issues Subject: Exchanged cached mode Sorry for the very basic question here. What is the difference between cached and un-cached mode in the client setting for Exchange? I am not the Exchange admin, you could not pay me enough to take on that extra work, but I do have to support the clients. We are moving from a Linux POP/IMAP server to Exchange and all of my clients are currently set up to POP their mail. I do have mobile clients that I already know will be an issue but I will start on that later. At the moment I am looking at just getting this setup and understanding why somethings are certain ways and not other ways. I will discuss specific issues with the Exchange admin. Any guidance would help a lot. Specific reading for non-Exchange aware people would be more help.
