I think I spoke to soon on this one. if the exchange server time is off
or it is trying to sync objects down from exchange the
lastmodificationtime will be greater that the local sync date time.
back to square one. Anyone have any other ideas?

Thanks Dmitry for your help, I figured I would post back what I ended up
implementing. For whatever reason i had forgotten, code bloat possibly,
that I had kept a lastsyncdate variable so in the ItemChange handler I
check the lastmodificationTime of the outlook object against the last
sync date, if the modtime is greater I save to my db file otherwise I do
not nothing.
Thanks,
Rog

No, you wouldn't be able to know what exactly caused that event to fire.

Good suggestion Dmitry, so does that mean there is no way to catch
this exchange sync event programmatically within Outlook? If I
triggered the exchange sync to happen so that I could control my flag
and not save to my local db file, would I be able to prevent it from
happening at another time besides when the user saves the item?

Hmmm.. I do not see that secondd event in the cached mode...
I guess you could store a hash made out of the values that you care
about (e.g .Email1Address + FileAs + ...) - if the hash is still the
same, do nothing.

Thanks Dmitry, so what happens is I save the contact in the code,
ItemChange fires, of course, but b/c my flag is set, I do not
resave it again to my local db. But then it seems b/c I just saved
the Contact about 30 seconds later the ItemChange event fires b/c
it seems that Exchange is doing the synchronization.
Does this make sense?

I sam confused - why would ItemChange fire if you did not change
it again? Or if a new change did not come from the EX server?

Thanks Dmitry for your response. Well basically once a user does
a save I capture the ItemChange event and log the item that was
change to a local db. Then when they click a button I try to sync
to the contact up to a server based on the values from the local
db file. In addition to syncing from outlok I also sync down from
the server to outlook and save the item. During the syncing I set
a flag so anything that is saved will not trigged the ItemChange
event, but once my sync process is complete, I change the flag to
capture the next time someone modifies a contact. So the problem
is about 30 secs after my sync process is complete and the flag
is reset, Outlook syncs with exchange which causes the ItemChange
event to fire and me to resave the item as modified in my local b
file which triggers the whole process over again when nothing has
really changed.
Does that make sense?

No, the cached Exchange provider provides no notification.
Why wouldn't you want to run your code? Does it matter whether a
change occured because the current user modified an item or
because it got modified on a different machine and the Exchange
provider received the notification and updated the local copy?

I am using the ItemChange event in my C# code to capture when
an item is saved and then do something with it. The problem is
I do not want to do this action when Exchange is syncing. Is
there anyway to determine when exchange is doing its auto-sync
so i can not run the code?
Thanks so much
