How to get Outlook Email received time - vba

Question

I need to extract attachments from Emails received in a user preferred time frame.
Say like extract for Emails received between 2PM to 4PM.
Please find the below code I've that extract files perfectly - but it did for all the Emails in the folder.
Please help me to resolve it.
Sub Unzip()
Dim ns As NameSpace 'variables for the main functionality
Dim Inbox As MAPIFolder
Dim SubFolder As MAPIFolder
Dim Atchmt As Attachment
Dim FileName As Variant
Dim msg As Outlook.MailItem
Dim FSO As Object 'variables for unzipping
Dim oApp As Object
Dim FileNameFolder As Variant
Dim Totalmsg As Object
Dim oFrom
Dim oEnd
Set ns = GetNamespace("MAPI")
Set Inbox = ns.GetDefaultFolder(olFolderInbox)
Set SubFolder = Inbox.Folders("TEST")
Set Totalmsg = msg.ReceivedTime
oFrom = InputBox("Please give start time", ("Shadowserver report"))
oEnd = InputBox("Please give End time", ("Shadowserver report"))
If Totalmsg <= oFrom And Totalmsg >= oEnd Then
For Each msg In SubFolder.Items
For Each Atchmt In msg.Attachments
If (Right(Atchmt.FileName, 3) = "zip") Then
MsgBox "1"
FileNameFolder = "C:\Users\xxxx\Documents\test\"
FileName = FileNameFolder & Atchmt.FileName
Atchmt.SaveAsFile FileName
Set oApp = CreateObject("Shell.Application")
oApp.NameSpace(FileNameFolder).CopyHere oApp.NameSpace(FileName).Items
Kill (FileName)
On Error Resume Next
Set FSO = CreateObject("scripting.filesystemobject")
FSO.deletefolder Environ("Temp") & "\Temporary Directory*", True
End If
Next
Next
End If
End Sub

Made a few improvements to improve performance and clarity :
Test received time inside the loop on the messages
Defined related variables as Date (like MsG.ReceivedTime) and improved input messages
Added Option Explicit to avoid mishaps in future coding (VERY GOOD PRACTICE)
Use Environ$("USERPROFILE") to get User directory's path
Reorganize variables and initialisation outside of the loops
Added LCase to be sure to get all zips (including .ZIP)
Code :
Option Explicit
Sub Unzip()
'''Variables for the main functionality
Dim NS As NameSpace
Dim InboX As MAPIFolder
Dim SubFolder As MAPIFolder
Dim MsG As Outlook.MailItem
Dim AtcHmt As Attachment
Dim ReceivedHour As Date
Dim oFrom As Date
Dim oEnd As Date
'''Variables for unzipping
Dim FSO As Object
Dim ShellApp As Object
Set FSO = CreateObject("Scripting.FileSystemObject")
Set ShellApp = CreateObject("Shell.Application")
Dim FileNameFolder As Variant
Dim FileName As Variant
'''Define the Outlook folder you want to scan
Set NS = GetNamespace("MAPI")
Set InboX = NS.GetDefaultFolder(olFolderInbox)
Set SubFolder = InboX.Folders("TEST")
'''Define the folder where you want to save attachments
FileNameFolder = Environ$("USERPROFILE") & "\Documents\test\"
'''Define the hours in between which you want to apply the extraction
oFrom = CDate(InputBox("Please give Start time" & vbCrLf & _
"Example: 9AM", ("Shadowserver report"), "9AM"))
oEnd = CDate(InputBox("Please give End time" & vbCrLf & _
"Example: 6PM", ("Shadowserver report"), "6PM"))
For Each MsG In SubFolder.items
ReceivedHour = MsG.ReceivedTime
If oFrom <= TimeValue(ReceivedHour) And _
TimeValue(ReceivedHour) <= oEnd Then
For Each AtcHmt In MsG.Attachments
FileName = AtcHmt.FileName
If LCase(Right(FileName, 3)) <> "zip" Then
Else
FileName = FileNameFolder & FileName
AtcHmt.SaveAsFile FileName
ShellApp.NameSpace(FileNameFolder).CopyHere _
ShellApp.NameSpace(FileName).items
Kill (FileName)
On Error Resume Next
FSO.deletefolder Environ$("Temp") & "\Temporary Directory*", True
End If
Next AtcHmt
End If
Next MsG
End Sub

I am just going to include the part that you need to change. Other lines will be the same. Basically, what you need to do is to set the Totalmsg inside your loop for each msg;
Sub Unzip()
'... copy your code till here
Set SubFolder = Inbox.Folders("TEST")
oFrom = InputBox("Please give start time", ("Shadowserver report"))
oEnd = InputBox("Please give End time", ("Shadowserver report"))
For Each msg In SubFolder.Items
Set Totalmsg = msg.ReceivedTime
If Totalmsg <= oFrom And Totalmsg >= oEnd Then 'You check it for each msg
'rest will be the same until ...
FSO.deletefolder Environ("Temp") & "\Temporary Directory*", True
End If
Next
End If
Next
End Sub
