Hi there, I just setup an Exchange 2003 Server and was wondering how many Admins out there favor the Cache mode and how many don't and the reasons why. I'm new to Exchange but it seems like the cache mode could be a good thing if there ever was a problem with the Email server as people could still atleast open Outlook to read or print off critical emails and still get their contacts. Without cached mode they just receive an error message that Outlook can't open. Seems like cached mode would be a must for traveling laptop users. Your input would be greatly appreciated.

Cached mode is a great if you have a WAN. If it is a LAN, not too much difference other than what you mentioned about the server being down.

You are correct that themobile users need Cached mode.

If you have a WAN environment with slow links you would want those users to also have it.

If you have a stable Exchange server on a small network you might not want it at all.

If you have little faith in the current backup\recovery process you want ALL users to have it.

It's a good thing for Disaster recovery to have that 1 extra level of backup but it will eat at the users profile space on the local machine. Particularly for those users that like to same every e-mail from the windows 3.1 days. This will cause a user to have a longer login process.

If the users have roaming profiles you DON'T want that as it will cause the profile to take a long time to load on a new PC.

There are a lot of reasons both for and against. Take a close look at what you have and setup however YOU are comfortable. Remember that when it all hits the fan, it YOUR head on the block. As long as you don't impact the users they won't care either way.

I've setup both ways depending on what my customer wanted.

Best of luck.
