Trying to add a default signature into an email from VBA

If the answer to the above is yes, then this should work:

Sub Mail_workbook_Outlook_1()
    Dim OutApp As Object
    Dim OutMail As Outlook.MailItem
    Dim signature As String
    
    EmailTo = Worksheets("E-mail Sheet").Range("B26")
    
    Dim Found As Range
    
    EmailTo = Worksheets("E-mail Sheet").Range("B26")
    
    Set Found = Sheets("Current Clients").Columns("C").Find(What:=Sheets("E-mail Sheet").Range("A26").Value, _
        LookIn:=xlValues, LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:=False)
                                               
    If Not Found Is Nothing Then
        If IsEmpty(Found.Offset(, -2)) = False Then
            If MsgBox(Range("A26").Value & vbNewLine & vbNewLine & "An item request has  been sent on: " & Found.Offset(, -2).Value & vbNewLine & _
            "Items were recieved on: " & Found.Offset(, -1).Value & vbNewLine & vbNewLine & "See Current Clients page for more information" & vbNewLine & vbNewLine _
            & "Do you want to continue?", vbYesNo) = vbNo Then
                Exit Sub ' stop macro if user selects No
            End If
        End If
    End If

    
    Set OutApp = CreateObject("Outlook.Application")
    Set OutMail = OutApp.CreateItem(0)

    On Error Resume Next
    With OutMail
        .display
        signature = .htmlBody
        .To = Worksheets("E-mail Sheet").Range("B26")
        .CC = Worksheets("E-mail Sheet").Range("B19")
        .BCC = ""
        .Subject = "Updating Credit File - " & Worksheets("E-mail Sheet").Range("D26")
        .htmlBody = "Dear " & Worksheets("E-mail Sheet").Range("C26") & "," & "<br><br>" & _

Arkadi, thanks for the reply!
I should have specified that the signature is a default for my 2nd email account, but it's not the default signature for the default email account. The code I have here sends the email from the 2nd Outlook account, so I figured it would pull that default signature with your code, however it is not. Any suggestions? Thanks again!
