VBA code to delete emails after x Days

Question

I am trying to delete all emails in my inbox that are older than 90 days. I am not able to use the auto archive since it has been disabled at my office. I have some code that does not seem to be deleting every mail that is older than 90 days. I think the issue might be with my loop. I am using Outlook 2010 with exchange 2010.

Private Sub RemoveEmail90()

Dim olSession As Outlook.Application, olNamespace As NameSpace
Dim olInbox As Outlook.MAPIFolder
Dim i As Integer
Set olSession = New Outlook.Application
Set olNamespace = olSession.GetNamespace("MAPI")
Set olInbox = olNamespace.GetDefaultFolder(olFolderInbox)
Set Delete_Items = olInbox.Items

For i = Delete_Items.Count To 1 Step -1
    If TypeName(Delete_Items.Item(i)) = "MailItem" Then
            If DateDiff("d",now, Delete_Items.Item(i).ReceivedTime) > 90 Then Delete_Items.Item(i).Delete
    End If
Next

Set olSession = Nothing
Set olNamespace = Nothing
Set olInbox = Nothing
End Sub

I was able to fix it by tweaking the code. Now the code runs just fine. I change the "m" on line 13 to a "d" and now it is deleting all older emails. Updated code Above.

If DateDiff("d",now, Delete_Items.Item(i).ReceivedTime) > 90 Then Delete_Items.Item(i).Delete
