Hi,

Im using VSTO to build an add in for Outlook 2007.

The problem In my add in is that I need to know which permissions the users

has.

For example: I need to know if the user has permission to "Send As" and I

need to get this information runtime in code.

After spending more time I intended to learn this by searching I now hope

that someone here has an answer.
 
That's not directly exposed in the Outlook 2007 object model. You can use

the Folder.PropertyAccessor() object on these properties, both are PT_LONG

(int32) that are bit flag values:

PR_ACCESS "http://schemas.microsoft.com/mapi/proptag/0x0FF40003"

PR_ACCESS_LEVEL "http://schemas.microsoft.com/mapi/proptag/0x0FF70003"

The DASL property tags for the properties are what you'd supply to

PropertyAccessor().

You then have to interpret the bit flags.

The same properties are also available on individual items, and on Store the

PR_ACCESS_LEVEL property is available. The bit flags such as MAPI_MODIFY are

in the mapidefs.h header file that's in most of the Windows and Exchange

SDK's.

However, that won't tell you some properties such as SendAs or ReceiveAs

permissions. For those you'd need to query the server. For that you could

use an LDAP query, or WebDAV or Exchange Web Services or a cmdlet, depending

on what version of Exchange is being queried. For more on that sort of stuff

you need to post in an Exchange development group such as

microsoft.public.exchange.development.

Ok, but feels like thats something that should have been exposed in the

object model thou. The problem is that I started with reading (LDAP) from the

AD directly but couldn't access the properties of the exchange - only the

ordinary stuff so that why I thought that this would be accessible through

the outlook Object model.

Do you know of any example on how to obtain this data through LDAP?

The access properties are exposed that way, SendAs or ReceiveAs are purely

server side properties so they aren't in the object model. They mean nothing

in the case of a PST file for example, and only relate to Exchange.

There may be better ways than using LDAP, such as WebDAV or Exchange Web

services or a cmdlet, depending on what version of Exchange is being used. I

don't do that much with that sort of thing so that's why I suggested asking

about that in an Exchange development group.

On the MAPI level (C++ or Delphi), you can open the

PR_EMS_AB_PUBLIC_DELEGATES_BL_O and PR_EMS_AB_PUBLIC_DELEGATES properties as

IMAPITable objects. Redemption (url below) exposes these as

RDOAddressEntry.Delegates and RDOAddressEntry.IsDelegateFor collections -

http://www.dimastr.com/redemption/rdo/rdoaddressentry.htm

Folder level access settings can be retrieved by opening the PR_ACL_TABLE

property as IExchangeModifyTable from the IMAPIFolder objeect

(IMAPIFolder::OpenProperty). Redemption exposes ACL through the

RDOFolder.ACL collection: http://www.dimastr.com/redemption/rdo/rdoacl.htm
