Afterwoards I exporting the contact to outlook.

If the contact exits, I have to delet them and then I creating a new one,
but I loosing now informations, which were made in the contact.

How could I synchronize contacts?

The simplest solution would be to look at the modified dates of a contact in
Access and Outlook (not even close to being 100% fool proof) and decide
which contact is the newest based on these dates.

Hi Dimitry

Many thanks for your reply.

One of the main problem for me is the saving of the new contact. I loosing
informations like picture, exchange ..... I do not have any informations in
the view in access. There are only: FirstName, name, adress ....

How could I save only this updatet informations to the existing contact? The
EntryID is read only.

Many thanks

Regards

You should not be deleting an existing contact and re-creating a new one.
For an existing contact, you only need to update the fields that you are
aware of; there is no reason to modify any other fields.

I am not sure I understand why this is a problem.
Do you *always* create a new contact? Are you saying you cannot search
for/open an existing contact?
