Cannot see shortcut icons in Outlook 2007

We have just installed Sourceone 6.5.2.6031 and our clients are running Office 2007

The forms are showing up fine in Tools - Options - Other - Advanced Options - Custom Forms - Manage Forms

I have run an archiving and shortut archiving job and can search for archived messages but no icons are showing up in Outlook.

I have tried reinstalling Outlook and repairing Outlook on 2 different machines,

This is happening for both users we have selected to test on.

Now stuck for ideas going forward.

Any help appreciated thanks
