In reading that again it infers that for OSTs you are going to get this
discrepancy, but for PSTs this will not occur because the PST is not
RTF-aware?????

Subject: RE: PST Question

Outlook 2003 (In cached mode) and Exchange 2003 -  When I get the Folder
Sizes dialog that lists each folder and size in each, There are two tabs
in the Folder Sizes dialog box in the client properties in Outlook,
local and server. They Show:

Local Data Total Size (including subfolders) 136855 KB Server Data Total
Size (including subfolders) 83997 KB 

The Local is significantly larger than the Server because there are two
copies of each message in the OST, one in Unicode and one in RTF.

Working with Text in Rich Text Format

The body of a message in a Microsoft Exchange Server information store
is kept in the PR_RTF_COMPRESSED property. As the name implies, this
property contains compressed text that includes rich text formatting
information. For this reason, the body of any message that will at some
time be stored in a Microsoft Exchange Server information store or
transmitted by Microsoft Exchange Server can most efficiently be stored
in this property and not, for example, in the PR_BODY property. This
section describes various ways to work with text contained within or
destined for the PR_RTF_COMPRESSED property.

RTF-Awareness
An information store is known as RTF-aware* if it keeps the body and the
RTF text of a message synchronized. The server information store and the
offline folder store (OST) are RTF-aware and the personal folder store
(PST) is not RTF-aware. 

The MAPI RTFSync function synchronizes PR_BODY and PR_RTF_COMPRESSED,
ensuring that the rich text format body of a message matches the plain
text body. You call this function before reading the RTF body and after
modifying the RTF body. This is necessary for when working with the PST.
For the server information store and the OST, you do not need perform
this extra step. For information about RTF-awareness in message stores,
see the MAPI Programmer's Reference.

*RTF-Aware
An information store is known as RTF-aware if it keeps the body and the
RTF text of a message synchronized. The server-based information store
and the offline folder store (OST) are RTF-aware. The personal folder
store (PST) is not RTF-aware. See also About Information Store Client
and Server Components.
