Outlook custom plugin code not working as expected (Downlaod Email attachment) - outlook

Question

I am tring to save attachemnt from a incoming mail in outllok. This is my code. My issue is it downloads correctly when email arrives(when my laptop is open), but this mail is scheduled everyday at 6:00 AM, I open my laptop at 9 and mail is already present and it is not downloading as expected?Do i need to do anything with code?
const string destinationDirectory = #"\\prod_data\Service Now\";
Outlook.MAPIFolder inBox = this.Application.ActiveExplorer()
.Session.GetDefaultFolder(Outlook
.OlDefaultFolders.olFolderInbox);
Outlook.Items inBoxItems = inBox.Items;
Outlook.MailItem newEmail = null;
inBoxItems = inBoxItems.Restrict("[Unread] = true");
try
{
foreach (object collectionItem in inBoxItems)
{
newEmail = collectionItem as Outlook.MailItem;
if (newEmail != null)
{
if (newEmail.Attachments.Count > 0)
{
for (int i = 1; i <= newEmail
.Attachments.Count; i++)
{
if (newEmail.Attachments[i].FileName.Contains( "LogicView Issue Report"))
{
newEmail.Attachments[i].SaveAsFile(destinationDirectory +
newEmail.Attachments[i].FileName);
}
}
}
}
}
}

I'd suggest checking out the MarkForDownload property value. It returns an OlRemoteStatus constant that determines the status of an item once it is received by a remote user. For example:
Sub DownloadItems()
Dim mpfInbox As Outlook.Folder
Dim obj As Object
Dim i As Integer
Set mpfInbox = Application.GetNamespace("MAPI").GetDefaultFolder(olFolderInbox)
'Loop all items in the Inbox folder
For i = 1 To mpfInbox.Items.Count
Set obj = mpfInbox.Items.Item(i)
'Verify if the state of the item is olHeaderOnly
If obj.DownloadState = olHeaderOnly Then
MsgBox ("This item has not been fully downloaded.")
'Mark the item to be downloaded.
obj.MarkForDownload = olMarkedForDownload
End If
Next
End Sub
You can use the Start method of the SyncObject class to begin synchronizing a user's folders using the specified Send\Receive group.

Do not use Application.NewMail event - it fires only when Outlook is running at the time the email is received by the Exchange server.
Use Items.ItemAdd event on the Inbox folder (Namespace.GetDefaultFolder(olFolderInbox)) - it will fire when the email downloaded to the cached store when Outlook synchronizes the Inbox folder (assuming you are using cached mode). If Outlook is online, no events will fire. In that case, you can use Items.Find/FindNext to process all unread messages ([Unread] = 'true').
//declare on the global/class level to make sure
//it does not get garbage collected
private Outlook.Items inBoxItems;
...
//in your addin startup code
inBoxItems = inBox.Items
inBoxItems.ItemAdd += inboxItemsItemAdd;
...
private void inboxItemsItemAdd(object item)
{
...
}
