October 12 2017 A security update released on October 10 2017 removes the Home Page tab from Outlook 2010, 2013, and 2016. This change was made for security reasons but because so many applications use Folder Home Pages, Microsoft has a registry key available to re-enable folder home page support.
An earlier update, back in 2011, removed folder home pages from non-default data files. If you need to use a folder home page in a non-default folder, you'll also need to set the NonDefaultStoreScript value at the bottom of this page.
Remember: if a registry key doesn't exist, you'll need to create it!
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Security DWORD: EnableRoamingFolderHomepages Value: 1
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\15.0\Outlook\Security DWORD: EnableRoamingFolderHomepages Value: 1
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\14.0\Outlook\Security DWORD: EnableRoamingFolderHomepages Value: 1
Do it for me
Folder Home Pages in Non-Default Data files
Problem: When you right-click on any of the folders that are listed down the left hand side in Outlook and choose Properties and then Home Page tab, the Home Page feature is disabled, preventing you from changing the address.
The home page setting is disabled in non-default data files "by design", beginning with Outlook 2007. If you want to use a folder home page in other data files and the URL field is grayed out, you'll need to configure a registry key to enable it.
You need to edit the following registry key and add the NonDefaultStoreScript value:
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\16.0\outlook\security DWORD: NonDefaultStoreScript Value Data: 1 (Hexadecimal) to enable.
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\15.0\outlook\security DWORD: NonDefaultStoreScript Value Data: 1 (Hexadecimal) to enable.
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\14.0\outlook\security DWORD: NonDefaultStoreScript Value Data: 1 (Hexadecimal) to enable.
HKEY_CURRENT_USER\Software\Policies\Microsoft\office\12.0\outlook\security DWORD: NonDefaultStoreScript Value Data: 1 (Hexadecimal) to enable.
After setting the registry value, you may need to restart Outlook for it to take effect.
Note that the Show folder home page checkbox is disabled (grayed out) until you enter a URL in the Address field.
Do It For Me
If you don't want to edit the registry, download and run the appropriate reg file for your version of Outlook.
You cannot add a URL to the Address box on the Home Page tab in Outlook 2007 MSKB (also applies to Outlook 2010)
Outlook does not support rendering all types of folder home pages
