Recently office products (excel and word) are opening some (not all) documents from network shares in "Protected view".

So far I have added the drive letter and the server name to the GPO's
       UC\Policies\Admin tools\Microsoft office 2016\security settings\trust center\Trusted Location #1 (and more)
       Added trusted locations for drive letters and server name with subfolders which should work.

I can turn the security mode off but this feels the wrong thing to do.  Am I missing something very obvious?

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection.  Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
