outlook contact can't get SMTP address, No MAPI properties on "exchange" contact list

Question

is it a bug in outlook?

i've created a local Contact list card, and i gave him in the address field an exchange user address. (double click on that address, see that its exchange).

when i try to get the address using MAPI - i can't, the problem is this, when i check the AddressEntry object, i get the following:

• Type = "EX"
• Address = "/o=.../ou=Exchange..."/cn=Recipients/cn=Name
• Class = olAddressEntry
• AddressEntryUserType = olOutlookContactAddressEntry

when i checked in OutlookSpy - no MAPI properties, so i can't get PR_SMTP_ADDRESS nor PR_EMS_AB_PROXY_ADDRESSES, also, this is not SMTP so i have no valid address.

---

i checked other users and those are the properties (which it works):

Real exchange user recipient, same email address as the exchange one, but it was created without autocorrect to the exchange user, so it stays smtp:

• Type = "SMTP"
• Address = "Email@email.com"
• Class = olAddressEntry
• AddressEntryUserType = olExchangeUserAddressEntry

Regular address entry

• Type = "EX"
• Address = "/o=.../ou=Exchange..."/cn=Recipients/cn=Name
• Class = olAddressEntry
• AddressEntryUserType = olOutlookContactAddressEntry

if i double click on the "exchange" local contact, it opens exchange window of its properties, if i open the "regular one i created manually", it opens the "SMTP" address window.

any workaround i can do?

thanks.

It didn't work in way "Dmitry Streblechenko" suggested because for some reason ContactItem.Email1EntryId, ContactItem.Email2EntryId and ContactItem.Email3EntryId contains not id but some wrong random data (even some html tags) - office 2016.

But it finally worked with following code

 using (var pa = new InteropWrapper<Outlook.PropertyAccessor>(contact.innerObject.PropertyAccessor))
            {
                String EMAIL1_ENTRYID = "http://schemas.microsoft.com/mapi/id/{00062004-0000-0000-C000-000000000046}/80850102";
                string emailEntryID = pa.innerObject.BinaryToString(pa.innerObject.GetProperty(EMAIL1_ENTRYID));

                using (var rs = new InteropWrapper<Outlook.NameSpace>(Globals.ThisAddIn.Application.Session))
                {
                    rs.innerObject.Logon();
                    using (var addressEntry = new InteropWrapper<Outlook.AddressEntry>(rs.innerObject.GetAddressEntryFromID(emailEntryID)))
                    using (var exchangeUser = new InteropWrapper<Outlook.ExchangeUser>(addressEntry.innerObject.GetExchangeUser()))
                    {
                        return exchangeUser.innerObject.PrimarySmtpAddress;
                    }
                }
            }

where InteropWrapper<T> just IDisposable wrapper around com object - it does Marshal.ReleaseComObject(innerObject) on dispose. So you can do everything without it by using Marshal.ReleaseComObject() directly.

just in case if someone need email 2 and email 3 including them here

String EMAIL2_ENTRYID = "http://schemas.microsoft.com/mapi/id/{00062004-0000-0000-C000-000000000046}/80950102";
String EMAIL3_ENTRYID = "http://schemas.microsoft.com/mapi/id/{00062004-0000-0000-C000-000000000046}/80A50102";

Hope it will save someones time! I've spent like a day on it.

If you have an EX type contact, use the value of the ContactItem.Email1EntryId property to call Namespace,GetAddressEntryFromId, then read the AddressEntry.GetExchangeUser.PrimarySmtpAddress property.
