What exactly are you trying to do?

Hi Dmitry,

I didn't see the value PR_LAST_MODIFICATION_TIME property in IMAPIFolder.
According to Sue and Ken, the property doesn't existing in folder. Thanks.

Do you see the changes in OutlookSpy (click IMAPIFolder, locate the
PR_LAST_MODIFICATION_TIME property) or MFCMAPI?

Hi Ken,

I tried RDOSession but the oFolder.Fields(&H30080040) value is = Empty.
Then i tried to change the name of the contact default folder to make
sure
the folder really changed. Try again but oFolder.Fields(&H30080040)
still
empty.

By the way, you commented that:

"use Application only in Outlook VBA, otherwise get Application object,
then
get NameSpace."

Why Application only in Outlook VBA? I tried Application in VB6 Com
Add-In
and it seems to work fine.

Thanks.

I'd probably use RDOSession myself:

Dim oSession As Redemption.RDOSession
Dim oFolder As Redemption.RDOFolder
Dim lastMod As Date

Set oSession = CreateObject("Redemption.RDOSession")
' use Application only in Outlook VBA, otherwise get Application
object,
then get NameSpace.
oSession.MAPIOBJECT = Application.Session.MAPIOBJECT
Set oFolder = oSession.GetDefaultFolder(olFolderContacts)
lastMod = oFolder.Fields(&H30080040)

Note that lastMod will be in UTC and not in local time. Use MAPIUtils
to
do
the conversion using the HrGMTToLocal() method.
