if you want to save all the attachments from multiple emails you can do it from outlook VBA code in Microsoft Visual Basic for Applications window in outlook, First lets create a folder, in this example you need to open a folder under “My Documents” call attachments

Then, in outlook type Alt + F11 keys to open the Microsoft Visual Basic for Applications window . insert new module and paste this code in :
Public Sub SaveAttachments()
'Update 20200821
Dim xMailItem As Outlook.MailItem
Dim xAttachments As Outlook.Attachments
Dim xSelection As Outlook.Selection
Dim i As Long
Dim xAttCount As Long
Dim xFilePath As String, xFolderPath As String, xSaveFiles As String
Dim xYesNo As Integer
Dim xFlag As Boolean
On Error Resume Next
xFolderPath = CreateObject("WScript.Shell").SpecialFolders(16)
Set xSelection = Outlook.Application.ActiveExplorer.Selection
xFolderPath = xFolderPath & "\Attachments\"
If VBA.Dir(xFolderPath, vbDirectory) = vbNullString Then
VBA.MkDir xFolderPath
End If
For Each xMailItem In xSelection
Set xAttachments = xMailItem.Attachments
xAttCount = xAttachments.Count
xSaveFiles = ""
If xAttCount > 0 Then
For i = xAttCount To 1 Step -1
xFilePath = xFolderPath & xAttachments.Item(i).FileName
xFlag = True
If VBA.Dir(xFilePath, 16) <> Empty Then
xYesNo = MsgBox("The file is exists, do you want to replace it", vbYesNo + vbInformation, "Kutools for Outlook")
If xYesNo = vbNo Then xFlag = False
End If
If xFlag = True Then
xAttachments.Item(i).SaveAsFile xFilePath
If xMailItem.BodyFormat <> olFormatHTML Then
xSaveFiles = xSaveFiles & vbCrLf & "<Error! Hyperlink reference not valid.>"
Else
xSaveFiles = xSaveFiles & "<br>" & "<a href='file://" & xFilePath & "'>" & xFilePath & "</a>"
End If
End If
Next i
End If
Next
Set xAttachments = Nothing
Set xMailItem = Nothing
Set xSelection = Nothing
End Sub
Highlight the email you want to extract the attachments from and run the script with F5
You will have all the attachments saved to the folder
Good Luck
