Excel VBA Code to retrieve e-mails from outlook - excel

Question

I am to write a VBA code that would retrive emails from Outlook based on certain conditions. The problem I have is that I have to denote a certain folder in my code (in the example below the folder denoted is "PRE Costumer". I would like to retrive all emails from my 'inbox' or in better case from all outlook folders. The problem is that my inbox consists of many subfolders (because of rules0. My problem is that I may not know all the subfolders names (as many useres are going to use the macro and even someone can have the e mails in Personal Folders).
Could you please advise is there a way to overcome this problem?
Please let me know if this question is vague (as I am newcomer)
Please find the line that I have probelm with marked with a comment.
Sub GetFromInbox()
Dim olApp As Outlook.Application
Dim olNs As Namespace
Dim Fldr As MAPIFolder
Dim olMail As Variant
Dim i As Integer
Set olApp = New Outlook.Application
Set olNs = olApp.GetNamespace("MAPI")
'Below is the line I have problem with
Set Fldr = olNs.GetDefaultFolder(olFolderInbox).Folders("PRE Customer")
i = 1
x = Date
For Each olMail In Fldr.Items
If InStr(olMail.Subject, "transactions") > 0 _
And InStr(olMail.ReceivedTime, x) > 0 Then
ActiveSheet.Cells(i, 1).Value = olMail.Subject
ActiveSheet.Cells(i, 2).Value = olMail.ReceivedTime
ActiveSheet.Cells(i, 3).Value = olMail.SenderName
i = i + 1
End If
Next olMail
Set Fldr = Nothing
Set olNs = Nothing
Set olApp = Nothing
End Sub

Just loop through all the folders in Inbox.
Something like this would work.
Edit1: This will avoid blank rows.
Sub test()
Dim olApp As Outlook.Application, olNs As Outlook.Namespace
Dim olFolder As Outlook.MAPIFolder, olMail As Outlook.MailItem
Dim eFolder As Outlook.Folder '~~> additional declaration
Dim i As Long
Dim x As Date, ws As Worksheet '~~> declare WS variable instead
Dim lrow As Long '~~> additional declaration
Set ws = Activesheet '~~> or you can be more explicit using the next line
'Set ws = Thisworkbook.Sheets("YourTargetSheet")
Set olApp = New Outlook.Application
Set olNs = olApp.GetNamespace("MAPI")
x = Date
For Each eFolder In olNs.GetDefaultFolder(olFolderInbox).Folders
'Debug.Print eFolder.Name
Set olFolder = olNs.GetDefaultFolder(olFolderInbox).Folders(eFolder.Name)
For i = olFolder.Items.Count To 1 Step -1
If TypeOf olFolder.Items(i) Is MailItem Then
Set olMail = olFolder.Items(i)
If InStr(olMail.Subject, "transactions") > 0 _
And InStr(olMail.ReceivedTime, x) > 0 Then
With ws
lrow = .Range("A" & .Rows.Count).End(xlup).Row
.Range("A" & lrow).Offset(1,0).value = olMail.Subject
.Range("A" & lrow).Offset(1,1).Value = olMail.ReceivedTime
.Range("A" & lrow).Offset(1,2).Value = olMail.SenderName
End With
End If
End If
Next i
Set olFolder = Nothing
Next eFolder
End Sub
Above takes care of all subfolders in Inbox.
Is this what you're trying?

To fix your error (olFolderInbox is a Outlook only constant, so you need to define it in vba that is not Outlook):
Const olFolderInbox = 6
'...
Set Fldr = olNs.GetDefaultFolder(olFolderInbox).Folders("PRE Customer")
Also to prevent missing Reference when run from another computer, I would:
Dim olApp As Object
Dim olNs As Object
Dim Fldr As Object
Dim olMail As Object
Dim i As Long
Set olApp = CreateObject("Outlook.Application")
'...
You might also want to disable ScreenUpdating, then enable it in Excel if you expect a long list.
UPDATE (Solution for all folders from a Root Folder)
I used something slightly different for comparing the dates.
Option Explicit
Private lRow As Long, x As Date, oWS As Worksheet
Sub GetFromInbox()
Const olFolderInbox = 6
Dim olApp As Object, olNs As Object
Dim oRootFldr As Object ' Root folder to start
Dim lCalcMode As Long
Set olApp = CreateObject("Outlook.Application")
Set olNs = olApp.GetNamespace("MAPI")
Set oRootFldr = olNs.GetDefaultFolder(olFolderInbox).Folders("PRE Customer")
Set oWS = ActiveSheet
x = Date
lRow = 1
lCalcMode = Application.Calculation
Application.Calculation = xlCalculationManual
Application.ScreenUpdating = False
GetFromFolder oRootFldr
Application.ScreenUpdating = True
Application.Calculation = lCalcMode
Set oWS = Nothing
Set oRootFldr = Nothing
Set olNs = Nothing
Set olApp = Nothing
End Sub
Private Sub GetFromFolder(oFldr As Object)
Dim oItem As Object, oSubFldr As Object
' Process all mail items in this folder
For Each oItem In oFldr.Items
If TypeName(oItem) = "MailItem" Then
With oItem
If InStr(1, .Subject, "transactions", vbTextCompare) > 0 And DateDiff("d", .ReceivedTime, x) = 0 Then
oWS.Cells(lRow, 1).Value = .Subject
oWS.Cells(lRow, 2).Value = .ReceivedTime
oWS.Cells(lRow, 3).Value = .SenderName
lRow = lRow + 1
End If
End With
End If
Next
' Recurse all Subfolders
For Each oSubFldr In oFldr.Folders
GetFromFolder oSubFldr
Next
End Sub
