VBA developers are very much familiar with the features of Microsoft .NET platform to develop custom AddIn for Office system... This tip is about to get an Outlook email entry id & programmatic way to retrieve the attachments and store into another location. A sample code example is given below:


<pre lang="cs>
private Outlook.Inspectors Inspectors;

private string _id;
public string Id
get { return _id; }
set { _id = value; }

private void ThisAddIn_Startup(object sender, System.EventArgs e)
Inspectors = this.Application.Inspectors;
Inspectors.NewInspector += new Microsoft.Office.Interop.Outlook.InspectorsEvents_NewInspectorEventHandler(GetMessageID);

private void GetMessageID(Microsoft.Office.Interop.Outlook.Inspector Inspector)
string strMsgID = string.Empty;

Outlook.MailItem _ObjMailItem = (Outlook.MailItem)Inspector.CurrentItem;

if (Inspector.CurrentItem is Outlook.MailItem)
_ObjMailItem = (Outlook.MailItem)Inspector.CurrentItem;
strMsgID = _ObjMailItem.EntryID;

foreach (Outlook.Attachment _attachment in _ObjMailItem.Attachments)
+ strMsgID
+ "-"
+ _attachment.FileName);

Id = strMsgID;

More information on Outlook.Inspectors can be found at this link.[^]

Does ThisAddin_startup code go in the Form1_Load sub?
What I did was create a ribbon with a button that opens a form. I then ask for a user id or lastname where I display a datagridview on result and then have them click on a row that gives me a Person ID. I hide the panel and then show another panel with more detail of that person. I want to then have the option to save the email body with a select of type of email... like Drug Screening, Back Ground Investication, ect... Then I want an option to save individual attachments again with attachment types. I would assume I would have a datagrid that would email body and this list off the individual attachments with a combobox column to save the files individual.

Any suggestions.
