Using VBA I can create an InternetExplorer object with 3 different tabs using the following

Option Explicit

Public Enum IE_READYSTATE
    Uninitialised = 0

    I have found an answer that appears to work, though I haven't done rigorous testing. I've modified your code so that I can run it without your clsIE module. This code navigates the tabs to 3 urls when opening them and then navigates them to new urls using the shellwindows object.

    I changed the do while .busy.. lines as they didn't work for the 2nd and 3rd tabs in that the state of the IE applecation was ready whilst the new tabs were still loading.

    Sub Example_Click()
    Dim ieApp As InternetExplorer
    Dim SWs As ShellWindows
    Dim IETab1Number As Integer
    Dim IETab2Number  As Integer
    Dim IETab3Number As Integer
    
    Set SWs = New ShellWindows
    
    'Create IE and login
    If ieApp Is Nothing Then
        Set ieApp = CreateObject("InternetExplorer.Application")
        With ieApp
    
           'IE Tab1
           .Visible = True
           .Navigate "http://www.bbc.co.uk/news/"
           Do While .Busy Or Not .ReadyState = IE_READYSTATE.complete: DoEvents: Loop
           IETab1Number = SWs.Count
    
           'IE Tab2
           .Navigate2 "http://www.bbc.co.uk/news/uk-scotland-north-east-orkney-shetland-23822420", CLng(2048)
           'Do While .Busy Or Not .ReadyState = IE_READYSTATE.complete: DoEvents: Loop
           Do While SWs.Count = IETab1Number: DoEvents: Loop
    
           IETab2Number = SWs.Count
    
           'IE Tab3
           .Navigate2 "http://www.bbc.co.uk", CLng(2048)
           'Do While .Busy Or Not .ReadyState = IE_READYSTATE.complete: DoEvents: Loop
           Do While SWs.Count = IETab2Number: DoEvents: Loop
           IETab3Number = SWs.Count
           'ieApp.Visible = False
    
           SWs.Item(IETab1Number - 1).Navigate "http://www.bbc.co.uk/"
           SWs.Item(IETab2Number - 1).Navigate2 "http://www.bbc.co.uk/news/"
           SWs.Item(IETab3Number - 1).Navigate2 "http://www.bbc.co.uk/news/"
    
    
        End With
    End If
    Set ieApp = Nothing
    Set SWs = Nothing
    
    End Sub
    

    It uses the ShellWindows to manipulate the tabs. This is only done by number so I'm guessing it could be prone to errors.

    To make it more robust you may want to get some info from the tab after an operation and check that the value is the same when returning to it. For example sPageTitle = SWs.Item(IETab3Number - 1).Document.Title could be used to store the title of the page in a tab, the next time you want to use the tab you can check that it hasn't changed.
