Exchange 2013/Windows 10/Office 2016
For a while this procedure has worked well

My Webpage

But the line
if AddrBook.ResolveName(Application.Handle, MAPI_DIALOG, nil, AdrList) = S_OK

is returning -2147221245 (not sure what that means) so fails to find the SMTP address.

Seems to work OK with earlier versions of Exchange.

Any ideas please?

Hello Nick,

-2147221245 stands for 80040103‬. A brief googling makes an impression that the issue relates to settings. I suggest that you talk to an administrator.

I can't find a relevant page either. The most close match is https://groups.google.com/forum/#!topic/microsoft.public.win32.programmer.messaging/jeQmhlYkEkk. BTW, it suggests another approach: try to ask this question on the Outlook for developers forum at https://social.msdn.microsoft.com/Forums/en-US/home?forum=outlookdev. Please invest in composing the title so that it catches attention of Dmitry Streblechenko; he's mentioned on the page above.

Thanks - that leads me to believe that what is going wrong is in string conversion prior to the call.

Delphi 5 (original version)
AdrList.aEntries[0].rgPropVals.Value.lpszA := PChar(Address);

if AddrBook.ResolveName(Application.Handle, MAPI_DIALOG, nil, AdrList) = S_OK then begin //no error

Delphi XE5 version
AdrList.aEntries[0].rgPropVals.Value.lpszA := PAnsiChar(Address);

if AddrBook.ResolveName(Application.Handle, MAPI_DIALOG, nil, AdrList) = S_OK then begin //error

I know not strictly your problem, but is there an alternative from changing PChar to PAnsiChar in XE5? Is it a unicode issue?

It may be. I've found out that this exception stands for MAPI_E_BAD_CHAR_WIDTH. This is all information I have for today. We are going to test that project in XE5 next week.

Thanks for the update. I have added the new GetSMTPAddress function, and it gets past the ResolveName issue, but then fails on:

if HrGetOneProp(AddrEntry, PR_EMS_AB_PROXY_ADDRESSES, propAddress) = S_OK then begin

returning a value of -2147024809.

Hello Nick,

What Outlook version are you using? Is it 32bit or 64bit?
