VBA - Find string in email body or subject - vba

Question

I am trying to create a simple macro, which reads the active email and checks whether or not a certain string is present. Now, the string can have two possible formats, and will only contains digits.
The two formats:
xxx-xxxxxxxx or xxxxxxxxxxx
(x will always be a digit)
I am unsure on how to do this. Below I have a macro, which reads the mail - but it can only find a specific string:
Sub AutomateReplyWithSearchString()
Dim myInspector As Outlook.Inspector
Dim myObject As Object
Dim myItem As Outlook.MailItem
Dim myDoc As Word.Document
Dim mySelection As Word.Selection
Dim strItem As String
Dim strGreeting As String
Set myInspector = Application.ActiveInspector
Set myObject = myInspector.CurrentItem
'The active inspector is displaying a mail item.
If myObject.MessageClass = "IPM.Note" And myInspector.IsWordMail = True Then
Set myItem = myInspector.CurrentItem
'Grab the body of the message using a Word Document object.
Set myDoc = myInspector.WordEditor
myDoc.Range.Find.ClearFormatting
Set mySelection = myDoc.Application.Selection
With mySelection.Find
.Text = "xxx-xxxxxxxx"
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchAllWordForms = False
.MatchSoundsLike = False
.MatchWildcards = True
End With
If mySelection.Find.Execute = True Then
strItem = mySelection.Text
'Mail item is in compose mode in the inspector
If myItem.Sent = False Then
strGreeting = "With reference to " + strItem
myDoc.Range.InsertBefore (strGreeting)
End If
Else
MsgBox "There is no item number in this message."
End If
End If
End Sub

You can use regex pattern:
(\d{11}|\d{3}-\d{8})
Try it.
This example is copied from here. I have not tested it.
Option Explicit
Sub GetValueUsingRegEx()
' Set reference to VB Script library
' Microsoft VBScript Regular Expressions 5.5
Dim olMail As Outlook.MailItem
Dim Reg1 As RegExp
Dim M1 As MatchCollection
Dim M As Match
Set olMail = Application.ActiveExplorer().Selection(1)
' Debug.Print olMail.Body
Set Reg1 = New RegExp
With Reg1
.Pattern = "(\d{11}|\d{3}-\d{8})"
.Global = True
End With
If Reg1.test(olMail.body) Then
Set M1 = Reg1.Execute(olMail.body)
For Each M In M1
Debug.Print M.SubMatches(1)
Next
End If
End Sub
