Hello,

I have tried it, but it's always the same behaivor once you access a contact item
Outlook pop's up a security dialog.

The solution seems to me is to use extented mapi like a tool called 'redemtion', but it is too
expensive.

Perhaps you know an other solution for D7 to access extendet mapi?

regards

That's weird because according to Microsoft:

"The Outlook default setting is to have Trust all installed add-ins and templates turned on. Unless you specifically have a reason to change this setting, you should not make this change."

and

"While Outlook does not provide a means to change this setting through the user interface, you can edit the Windows registry to force Outlook to not trust add-ins. For this registry setting to work, you must set the security level to Medium or High, on the Security Level tab, of the Security dialog box. If the security level is set to Low, you will not be warned about add-ins."

Outlook 2002 and above is obviously another story.

Kate

Otherwise there's guide to disable (registry way) the security warning;

1. Quit all corresponding running programs.      
2. Open registry key (9.0 should be your version instead i.e. 8.0) - HKEY_CURRENT_USER\Software\Microsoft\Office\9.0\Outlook\Security
3. If an entry exists named DontTrustInstalledFiles, change its value to 0 (or delete at all)
4. If the above isn't satisfaction then setup entry Level to value 0x01 = 1
5. This setting forces Outlook to not display a security warning when using COM add-ins.
6. If any of the keys exist i.e. Office\8.0\Outlook\Security (namely "8.0", "Outlook", "Security") create them

Kate

Hi,

you are nice!

It doesn't work!

MS itself's wrote, that in OL2000 there is no way to bypass security warnings.

Try this source but I'm positive that Outlook 2000
security is turned off by default.

There's also this BabelFish COM-Addin I suppose
if this one shouldn't go without triggering the security
it's not possible at all. Because it's professional Addin
so I would presume that they'll be able to override it.

Hello Katka,

thank you for your very good help!

I already know both Add-In's, they have the same problem with access to contact items.

The Extended Messaging API you found is very interesting!
