Extracting a word from Outlook Email Body while replying email with predefined Template

I have a working code which is extracting information from subject of initial email.

Sub InitialNotif()

Dim origEmail As MailItem

Dim replyEmail As MailItem

Dim INC1 As String  'For Serial Number

Dim INo As Integer  'For Serial Number

Dim LOC1 As String  'For Location

Dim LoC As Integer  'For Location

Dim SUMM As String  'For Summary

Dim Sum As Integer  'For Summary

Set origEmail = Application.ActiveWindow.Selection.item(1)

Set replyEmail = Application.CreateItemFromTemplate("H:\Documents\Test P1-.oft")

replyEmail.CC = ""

replyEmail.HtmlBody = replyEmail.HtmlBody & origEmail.Reply.HtmlBody

INC1 = origEmail.Subject

INo = InStr(1, INC1, "SR2")

LOC1 = origEmail.Subject

LoC= InStr(1, LOC1, "|") + 10

SUMM= origEmail.Subject

Sum= InStr(1, SUMM, "Summary") + 30

replyEmail.Subject = " <P1> - " & INC1

replyEmail.HtmlBody = Replace(replyEmail.HtmlBody, "INC1", INC1)

replyEmail.Display

End Sub

Now I would like to fetch information from body of the email. Below is the format of body of the email.

Serial Number: SR23443354
Location: Canada
Summary: Replacement request

I need above information to be replaced with my .otf Template. So when I run the script it should auto populate or replace required field.

Template Body:

Serial Number: INC1
Location: LOC
Summary: SUMM

When I tried replacing origEmail.Subject with origEmail.body its giving me entire email in scattered format.

Solution

Change ActiveWindow With ActiveExplorer

MSDN Split Function

MSDN Replace Function
