While from time to time some MS support folks do
post here, the newsgroups are generally peer to peer.
MS Office document imaging is primarily for support
OCR of printed and Faxed documents and archiving.
JPG (a lossy format) isn't particularly well suited
to either of those tasks. The Office XP MS Office
Document Imaging TIFF files used variants of the
TIFF format the spec allows, but as with other TIFFs
they may not then be as transportable or interchangeable

The MS Office 2003 Document Imaging product is an improved
version of MS Paper (MS Office Document Imaging from
the initial Office XP release). It adds
additional features such as editable annotations
using a TIFF derivative format, .MDI (MS Document Imaging).
For example, the JPEG compression support you mentioned -

Hi, I cannot open any of the .tif files that are made in Microsoft Office
Document Imaging program. Even though this program comes with Office XP, the
only file type you can save as in this program is the 13 YEAR OLD file format
tiff 6.0 jpeg format!! Come on microsoft - can someone please pass the
message on that they need to at least enable that program to save at LEAST
into a non-ancient file format like jpg itself! i Need a reply msoft <<
