Close Outlook via Access VBA

How can I close Outlook by using VBA code?  My RDC users are opening multiple instances of Outlook and that is causing problems/confusion.  I'd like to be able, upon opening a new Access form, to check to see if Outlook is open, and if it is, prevent another instance from opening.  If Outlook is not open, open it.

Best regards,

Hi, rhfarris.

You'll need something like the code below.  GetObject attempts to attach to an open Outlook session.  If there is one, then Err.Number will return 0.  If there isn't one, then Err.Number will return the error number which will be greater than 0.
Dim olkApp
On Error Resume Next
Set olkApp = GetObject(,"Outlook.Application")
If Err.Number > 0 Then
    'Outlook is not open so open it
Else
    'Outlook is already open
End If
Set olkApp = Nothing

Open in new window

Hi Rick,

How is your code doing it currently?  If you use the CreateObject function with outlook.application, it will either assign the currently open outlook to the variable, or create a new one if it doesn't exist.

Matt
 Dim olApp As Object 'you could also use Outlook.Application'
 Set olApp = CreateObject("outlook.application")
 'olApp now refers to the already-opened application if it existed, _
  or creates a new one if it did not exist'

Open in new window

Sorry BDF, I need to start refreshing again before posting :) Slightly different methods, but I don't like to impede on questions with responses.

    Dim oOutlook As Object
    Dim oNameSpace As Object
    Dim oInbox As Object
     
    Set oOutlook = CreateObject("Outlook.Application")
    Set oNameSpace = oOutlook.GetNamespace("MAPI")
    Set oInbox = oNameSpace.Folders(1)
     
    oOutlook.Quit  '<<< will close all open outlook

    Set oInbox = oInbox.Folders("Inbox")       'open a new one
    oInbox.Display

rhfarris,

Just a note here.

Whatever method you use, just do a quick check in the Task Manager to see if OUTLOOK.EXE is still running or not.
Sometime the Application Objects get left in memory.
