Outlook 2007 : How to obtain Proxy addresses using Outlook Object Model (for an ExchangeUser Object)?

Earlier i had a requirement, how to obtain Proxy addresses for a specific user programmatically'; also they preferred to do this by using Outlook Object Model API.

Please Note:

• The ExchangeUser object does not directly expose the proxy addresses for the user.
• However, you can use the PropertyAccessor object to obtain the MAPI property PR_EMS_AB_PROXY_ADDRESSES.
• This property is a multi-valued string property that contains all the foreign addresses for a given user.

Here is a simple code snippet, which returns an array of strings containing the proxy addresses for the ExchangeUser object passed as a method argument.

 private string[] GetProxyAddresses(Outlook.ExchangeUser exchUser) 

 { 

     const string PR_EMS_AB_PROXY_ADDRESSES = "https://schemas.microsoft.com/mapi/proptag/0x800F101E"; 

     if (exchUser != null) 

     { 

         return exchUser.PropertyAccessor.GetProperty( 

             PR_EMS_AB_PROXY_ADDRESSES) as string[]; 

     } 

     else 

     { 

         throw new ArgumentNullException(); 

     } 

 }

Hope this helps.
