When you want to open a template, you need to go through the Choose Form dialog, which is a few more steps than most users want to take. In older versions of Outlook you could create Hyperlink buttons but Outlook 2010 and newer doesn't support hyperlink buttons and tighter security in Outlook 2007 means you need to respond to a warning dialog before the template (or hyperlinked file) opens.

We have solutions for both problems: a macro for Outlook 2010 and newer (also works with Outlook 2007) and a registry key to disable the warning in Outlook 2007.

See Disable the Unsafe Hyperlink Warning when Opening Attachments for the instructions to disable the warning dialog and the Open or Save dialog. Use this registry value with Outlook 2010 if you add files to Outlook's Shortcut navigation pane.

Open templates using a toolbar button

To create a button on the toolbar that will open a template in Outlook 2010 and up, you need to use a macro as it does not support hyperlink buttons found in older versions of Outlook. Additionally, opening a template hyperlinked to a toolbar button in Outlook 2007 brings up a security dialog.

Note: if the template contains custom fields, the customizations will be disabled and the template will be blank. These templates need to be opened using the Choose Form dialog.

The solution

Create a macro that replicates opening a template from the Choose Form dialog using the Application.CreateItemFromTemplate method:

Sub MakeItem()
Set newItem = Application.CreateItemFromTemplate("c:\path\template.oft")
newItem.Display
Set newItem = Nothing
End Sub 

Press Alt+F11 to open Outlook's VB Editor then copy and paste this macro into ThisOutlookSession. Add it to the ribbon or QAT. See How to use the VBA Editor for complete instructions to use the VB Editor. See Customize the QAT if you need help customizing the QAT.

If you want to use a macro to open different templates, assign the template path to a variable and pass the variable to the macro, like this:

Dim template As String

Sub OpenTemplate1()
template = "C:\Users\Diane\Templates\template1.oft"
MakeItem
End Sub

Sub OpenTemplate2()
template = "C:\Users\Diane\Templates\email.oft"
MakeItem
End Sub

Private Sub MakeItem()
Set newItem = Application.CreateItemFromTemplate(template)
newItem.Display
Set newItem = Nothing
End Sub

Open a Template and Add an Attachment

If you want to add an attachment to the message at the same time you open the template, you'll use newItem.Attachments.Add "C:\myfile.doc". Add it to your code after the line that opens the template (DUH!) and before the message is displayed (newItem.Display).

The macro will look something like this:

Sub AddAttachment ()
Dim newItem as Outlook.MailItem
Set newItem = Application.CreateItem("C:\path\template.oft")
newItem.Attachments.Add "C:\myfile.doc"
newItem.Display
End Sub

Open a published form

If you want to open a published form, use this code to call the form. You need to be viewing the folder you want the item to be saved in.

Use GetDefaultFolder function to use the default folder for the custom form type. For example, change the Set items line to this the following to create an appointment or meeting in the Calendar folder from any other folder:
Set Items = Session.GetDefaultFolder(olFolderCalendar).Items

Public Sub OpenPublishedForm()
   Dim Items As Outlook.Items
   Dim Item As Object
   Set Items = Application.ActiveExplorer.CurrentFolder.Items
   Set Item = Items.Add("ipm.note.name")
   Item.Display
 End Sub

Add a button to the ribbon tutorial

This tutorial shows you how to add a button to one of Outlook 2013's ribbon tabs. If you prefer to add them to the Quick Access Toolbar (QAT), the steps are the same but you'll start in File, Options, Quick Access Toolbar. Note: In Outlook 2010 you cannot add buttons to the ribbon but you can add buttons to the QAT.

1. Select Macros from the Choose commands from menu
2. Select the macro. Only Public macros that you can run manually will be listed here.
3. Click Add to add it to the QAT (or ribbon)
4. To change the icon and display name, click Modify.

After you add a macro the ribbon, you cannot move the macro or change the macro or module name. If you do, you'll need to recreate the macro.

Select a template from File Open dialog

The macro will open the File Explorer dialog to a specific folder for you to choose a template. This macro uses late binding, so you won't need to set a reference to the Word object model to use it.

Sub ShowOpenDialog()
'Display the Open dialog box
Dim wdApp As Object ' Word.Application
Dim dlgOpen As Object ' FileDialog
Dim strFile As String

'Set wdApp = New Word.Application
Set wdApp = CreateObject("Word.Application")
 Dim vrtSelectedItem As Variant
    'Set the dialog box type to Open
    Set dlgOpen = wdApp.FileDialog(msoFileDialogFilePicker) 

'Show only Outlook templates in the specific folder path
    With dlgOpen
         .InitialFileName = "D:\Documents\Slipstick Templates\"
        .Filters.Add "Outlook Template", "*.oft"

  If .Show = -1 Then
      strFile = .SelectedItems(1)
  
    Set newItem = Application.CreateItemFromTemplate(strFile)
      newItem.Display
    Else
    ' user clicked cancel 
    End If

    End With

End Sub

Create a Hyperlink button

This works in Outlook 2007 and older versions as well as all Office applications that have the Assign Hyperlink option on customized buttons. You can hyperlink to any file, although programs (*.exe) may be restricted for security reasons.

You can use any button in the Customize dialog (select a category on the left to see additional buttons). If you want to create a menu button, there is a blank one in the New Menu category.

1. Right click on the toolbar area.
2. Choose Customize
3. From the Commands tab, drag a button (any button) to the Menu bar or a Toolbar
4. Right click on the button to expand the customize menu
5. Click Assign Hyperlink then Open and select the file you want to open.

Video Tutorial

In Outlook 2007's main interface and in Outlook 2003 and older, you'll add a button to the toolbar as shown in the following video.

Disable the hyperlink warning

When you open templates or files using a hyperlink button or from Outlook's Shortcut navigation pane, you'll receive an unsafe hyperlink warning. You can disable the warning by editing the registry.

You may also receive the file open or save dialog when using a hyperlink button or shortcut. To disable this dialog when the "Always ask" field is grayed out, run Outlook as administrator. The "always ask" checkbox should be clickable. If not, you'll need to edit the registry for each file type. See Disable "Always ask before opening" dialog for more information.

The solution

Add a registry value to disable the warning dialog.

Open the registry editor and browse to the following registry subkey for
Outlook 2016:
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Security

Outlook 2013:
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Security

Outlook 2010:
HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Common\Security

Outlook 2007:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\Security

Note: If the Security key does not exist in your registry, you'll need to create it too.

Right click on Security key and choose New, DWORD. Type (or paste)

DisableHyperlinkWarning as the Value name then double click on it. Enter 1 as the Value data to disable the warning. Delete the key or use a value of 0 to enable the warning.

Group policy keys for administrators

Administrators will add the DisableHyperlinkWarning DWORD to the Policy key instead:

Outlook 2016:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Common\Security

Outlook 2013:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\15.0\Common\Security

Outlook 2010:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Common\Security

Outlook 2007:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Common\Security

Do It For Me

If you don't want to edit the registry yourself, you can download and run the following registry key for your version of Outlook.

How to use the macros on this page

First: You need to have macro security set to the lowest setting, Enable all macros during testing. The macros will not work using the options that disable all macros or unsigned macros. You could choose the option to warn about macros and accept it each time you restart Outlook, however, because it's somewhat hard to sneak macros into Outlook (unlike in Word and Excel), allowing all macros is safe, especially during the testing phase. You can sign the macro when it is finished and change the security to allow signed macros.

To check your macro security in Outlook 2010 and newer, go to File, Options, Trust Center and open Trust Center Settings, and change the Macro Settings. In Outlook 2007 and older, look at Tools, Macro Security.

After you test the macro and see that it works, you can either leave macro security set to low or sign the macro.

Open the VBA Editor by pressing Alt+F11 on your keyboard.

To put the code in a module:

1. Right click on Project1 and choose Insert > Module
2. Copy and paste the macro into the new module.
