You cannot enable cached mode in any Outlook version prior to 2010 on a Terminal Server. Please see the following Microsoft article for details:

You can enable cached mode in Outlook 2010 on a RDSH (or TS). (I realize that the question and the article you linked is relevant to Outlook 2003, but I just wanted to add this for completeness). – joeqwerty Jul 14 '11 at 23:53
@joe - Thanks. I edited to clarify. – Jason Berg Jul 15 '11 at 2:25
Happy to add my two cents. – joeqwerty Jul 15 '11 at 3:19

Outlook 2003 and 2007 don't have an option to enable cached mode.

Here is a blog entry that describes how to enable an OST on Outlook 2003

OK, this is in response to the people who have posted on this subject. Someone was kind enough to give me the exact details, but I shall protect my sources except to say they know the insides of MS tools well.

The warning here is that this is unsupported and could completely destroy your users profiles, so only do this is you are comfortable editing the registry

The short description:

Open up Regedit

navigate to [HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\\13dbb0c8aa05101a9bb000aa002fc45a]

enter image description here

Find the key 00036601 (REG_BINARY) - note the number in it now so you can undo the changes if needed

Change the value to one of the following

•enabled value; 84 01 00 00 - note that on my desktop system the enabled value is 84 19 00 00, so play around with this a little •enabled with Public Folders/Favorites: 84 05 00 00 •disabled value; 04 00 00 00

enter image description here

FYI - you will need to search for "00036601" and adjust ALL of them since each key is for a different user on your system.
