Get the SMTP sender address from new opened Outlook mail inspector with C# (VSTO or redemption) when multiple accounts configured

Question

I've tried different approaches but I could not find a way to determine the sender address reliable from Outlook 2007 up to Outlook 2013 when multiple accounts can be selected in Outlook.

My addin is build on Add-In Express.

The aim is to get the account sender address from an active new mailitem (active mailinspector).

inspector = (AddinModule.CurrentInstance.OutlookApp as Outlook.Application).ActiveInspector();
mailitem = inspector.CurrentItem as Outlook.MailItem;

In Outlook 2013 it is possible to use:

mailitem.SendUsingAccount.CurrentUser.AddressEntry.Address

What can I do to get the sender address when my add-in is running on Outlook 2010 or 2007?

SendUsingAccount was added in Outlook 2007, so you should be good. I am not sure why you would want to use mailitem.SendUsingAccount.CurrentUser.AddressEntry.Address - you will always get the address of the default Outlook account. Have you tried to use mailitem.SendUsingAccount.SmtpAddress?

Thanks for your passion! It's strange. The SendUsingAccount property is null till I changed the sender address in the mail inspector by clicking the "from" dropdown. How to fix this problem? – aDoubleSo May 27 '14 at 07:49
Do you have any idea why this property is null? Thanks! – aDoubleSo May 27 '14 at 13:47

Unless the account was explicitly set, you will get back null. In that case you can assume that the default account was used. – Dmitry Streblechenko May 27 '14 at 20:46
Ok - I'll take the default account address if the value is null. thank you very much! – aDoubleSo Jun 02 '14 at 12:57
