I have received the following comment - "Wonder if there was an update that brought about a security change. The security change to enable a Trusted application to communicate with Outlook would be a good one to look at". But when I look at the Trust Center settings for Trusted Publishers there is only one entry (Intel Wireless Display). Can I add MS Access to this list in some way? But I can't see any way to do this!! Can someone guide me and maybe comment whether this might solve my problem?
