Hi,
Found some of these parameters from
"http://groups.google.co.in/group/microsoft.public.exchange.clients/browse_frm/th
read/3a2838c1ccda472/b261c3be8742b78a?lnk=st&q=PR_LAST_ACCESS_TIME&rnum=1&hl=en#
b261c3be8742b78a"
link. But when I tried to extract these properties on public folder
object, I got proper return values for

1. PR_DISPLAY_NAME
2. PR_MESSAGE_SIZE
3. PR_CONTENT_COUNT
4. PR_CONTENT_UNREAD
5. PR_REPLICATION_STYLE
5. PR_FOLDER_PATHNAME

but for other properties for the first public folder itself my code
will exit from the loop. This is not going further. Not sure why this
is so?

Other properties which I am interested are :
6. PR_INSTANCE_KEY
7. PR_EMAIL_ADDRESS
8. PR_LAST_ACCESS_TIME

Here with I have give my sample code which is not working while getting
6-8 properties.
----------------------------- connection to PUBLIC FOLDERS

//Initialize MAPI libraries
hr_p = MAPIInitialize (NULL);

hr_p = MAPILogonEx (NULL, "", NULL, MAPI_EXTENDED| MAPI_NEW_SESSION|
MAPI_LOGON_UI| MAPI_EXPLICIT_PROFILE,&pSession);

hr_p = HrOpenExchangePublicStore(pSession, &pmdbPublicACL);
hr_p = HrOpenExchangePublicFolders (pmdbPublicACL, &pRoot);
hr_dir = MAPICALL( pRoot)->GetHierarchyTable( MAPI_DEFERRED_ERRORS,
&lpTable);
hr_dir = HrQueryAllRows( lpTable, (LPSPropTagArray)&rgColProps, NULL,
NULL, 0L, &lpRow);

for(j = 0; j < lpRow->cRows; j++)
{
   hr_p = HrMAPIFindSubfolderEx (pRoot, PATH_SEP,
(LPCSTR)l_strFullPath, &cbeid, &lpeid);
   hr_p = pmdbPublicACL->OpenEntry ( cbeid, lpeid, NULL, MAPI_MODIFY,
&ulObjType,(LPUNKNOWN*)&pFolder );

}

For me it seems perfect as I was able to retrieve 1-5 properties in the
same way. But not sure what is wrong while getting 6-8 properties.
Could any one please help me to get this done?

Regards,
John
