After importing your contacts from a PDA or other importing tools, you will most probably encounter a problem of assigning phone numbers to category "Other" rather than "Mobile" or "Main (seen as work)".

One way of solving this issue is importing the contacts to Excel using internal Outlook mechanism and moving the data from one column to another. The fun starts when the target column is filled with data and simple overwriting the data is troublesome. As a result we are facing manual data overwriting.

I'd like to suggest a simple solution that consists of starting a procedure in VisualBAsic4App, which will move a phone number  to category "Other" and overwrite the data that exists there.

Sub Changing_mobile_other_to_main()
    Dim oContact As ContactItem
    Dim oContactFolder As MAPIFolder
    Dim Ile&, nCounter&, item As ContactItem
    Ile = 0
    oContactFolder = Application.GetNamespace("MAPI").GetDefaultFolder(olFolderContacts)
    For Each item In oContactFolder.Items
        DoEvents()
        Ile = Ile + 1
        oContact = item
        If Not oContact Is Nothing Then
            With oContact
                If Len(Trim(.PrimaryTelephoneNumber)) = 0 And _
                Len(Trim(.OtherTelephoneNumber)) > 0 Then
                    .PrimaryTelephoneNumber = Trim(.OtherTelephoneNumber)
                    .Save()
                    nCounter = nCounter + 1
                End If
            End With
        End If
        If Not oContact Is Nothing Then oContact = Nothing
    Next
    If Not oContactFolder Is Nothing Then oContactFolder = Nothing
MsgBox nCounter & " for" & How many & " processed contacts.", _
vbInformation, "Machine by OShon VBATools.pl"
End Sub
