Link data to a mail

Question

Hi,
I want to add data to a mail.
Actually i do somethinks like that :
public MailManager(MailItem mailItem, bool searchLinks = false) {
    // get data in mail
    Regex trRegExp = new Regex("<tr\\b[^>]*>(.*?)</tr>");
    Regex hrefRegExp = new Regex("href=\"([\\w\\W]*)\">");
    Regex strongRegExp = new Regex("<strong>([\\w\\W]*)</strong>");
void _inspector_BeforeAutoSave(ref bool Cancel) {
    // Block save
void _inspector_Write(ref bool Cancel) {
    // Add data in mail
/// <summary>
/// Occur when an user send a mail
/// </summary>
/// <param name="Cancel">bool to block avoid mail to be send by the system</param>
public void send(ref bool Cancel) {
    if (SendTasks == null) {
        Cancel = true;
        SendTasks = Task.Factory.StartNew(() => {
            AddLink();
            ((_MailItem)_inspector).Send();
I put data on the body and retrieve them when the draft is open. But i get three problems. It's a bit slow not much but not expected for just context keeping code. It's too hard to maintain, my real function start to be very big to manage every case.
Last but not least, there are no correct way to handle auto Save.
If i were MS i've make somethinks to bind data to à local mail per add-in. Is there somethinks like that or a proper way to do this.
Thanks.

Hello,
if (SendTasks == null) {
        Cancel = true;         SendTasks = Task.Factory.StartNew(() => {
            AddLink();
            ((_MailItem)_inspector).Send();
First of all, you shouldn't use any Outlook object model property or methods on secondary threads. Office applications uses the single-threaded apartments and doesn't support multithreading. All calls made on the secondary thread will be marshalled to the
primary one by Outlook automatically in the background. It will slow down the performance may introduce other issues in previous Outlook versions.
Why do you need to re-send the item anew and not add the required data in the event handler?
For example, you may consider handling the
ItemSend event of the Application class which is fired whenever an Microsoft Outlook item is sent, either by the user through an Inspector (before
the inspector is closed, but after the user clicks the Send button) or when the Send method
for an Outlook item, such as MailItem,
is used in a program.
