How to Attach Files with Dates in VBA - vba

Question

I have a macro that generates emails but I want to make this macro attach specific files with a date.
The date I want the macro to find when searching for the files is this:
lastSunday = DateAdd("d", 1 - Weekday(Now), Now)
Format(lastSunday, "dd-MM-yyyy")
Here is my full Macro:
Sub macro()
Dim OutApp As Object, OutMail As Object
Dim emailTo As String, emailCC As String
Dim lastSunday As Date
Dim c As Range
lastSunday = DateAdd("d", 1 - Weekday(Now), Now)
emailTo = WorksheetFunction.TextJoin(";", True, ActiveSheet.Range("Table22[To]"))
emailCC = WorksheetFunction.TextJoin(";", True, ActiveSheet.Range("Table22[CC]"))
Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)
With OutMail
.To = emailTo
.CC = emailCC
.Subject = "Weekly Reports - " & Format(lastSunday, "dd-MM-yyyy")
.Body = "Dear all," & vbCrLf & vbCrLf & _
"Please find attached the Weekly report" & vbCrLf & vbCrLf & "Hope this helps, please let me know if you require any additional detail." & vbCrLf & vbCrLf & "Kind regards,"
'.Attachments.Add "S:documents\[filename - DD-mm-YYYY]"
OutMail.Display
End With
End Sub

Answer 1

The Attachments.Add method creates a new attachment in the Attachments collection. The source of the attachment can be a file (represented by the full file system path with a file name) or an Outlook item that constitutes the attachment. So, you need to be sure the file doesn't contain forbidden symbols (it is a valid filename) and the file is located locally, for example:
Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)
With OutMail
.To = emailTo
.CC = emailCC
.Subject = "Weekly Reports - " & Format(lastSunday, "dd-MM-yyyy")
.Body = "Dear all," & vbCrLf & vbCrLf & _
"Please find attached the Weekly report" & vbCrLf & vbCrLf & "Hope this helps, please let me know if you require any additional detail." & vbCrLf & vbCrLf & "Kind regards,"
.Attachments.Add "S:\documents\filename - " & Format(lastSunday, "dd-MM-yyyy") & ".ext"
OutMail.Display
End With
