To what extend are you suffering from performance degradation and what do
you call "large" mailboxes.

As I said before; when you have multiple users on a TS and use ost-files
you'll have much more disk overhead (which already is high on a TS) and thus
performance degradation than connecting to the Exchange server directly.

Also check the performance bottlenecks on both the Exchange and TS Server.
As a general rule of thumb for the TS you can use 10MB of memory per
connection and at least 8MB per Office application per user (so if you use
Word as the email editor at least 16MB).

You can also use the Terminal Server scaling tools to calculate what your
server needs.

So how to you combat the performance degredation users see when they have
large mailboxes and are working off of temrinal services?

And theirs no way to tweak it to make it work?

No, Cached Mode on a Terminal Server is not supported since it would
cause a
lot of disk overhead.

Hello. I have Outlook 2003 installed on a Windows 2003 TS. I know
there
are
a lot of reasons NOT to have cached mode, but I have some instances
where
it
would be of great benefit to have this enabled.

Can this be done, either by modifying the registry or by any other
means?
