Bit desperate because I already posted to 2 microsoft official forums with hardly any views... :(
Here's my sad story...
For optimalisation reasons I generated and copied links to particular OneNote 2016 pages (Office 365 - Win7 64bit), which I use frequently.
They are in the format "onenote: / NAME OF PAGE / plenty of random hash numbers / location on hard drive".
I put them on my HDD (desktop) in new shortcut files, and assigned a hotkey to each as is standard Windows feature.
This works just as designed, except for a major obstacle: each time I use the link (any which way I use it, by hotkey or clicking or etc), I get an MS Office OneNote Security Warning "Microsoft Office has identified a potential security concern / Hyperlinks can be harmful...", which I need to click yes to.
Of course the whole point of the shortcut was to have immediate access to the page, not having to click the popup away.
I tried to look for the "Check Microsoft Office documents that are from or link to suspicious Web sites." option in OneNote TrustCenter - there isn't anything remotely similar in mine.
I tried the registry option of DisableHyperlinkWarning 1, in fact I already had that, in Common\Security for Office "16.0".
Also tried new key (not dword, as per instruction) "onenote:" in
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Common\Security\Trusted Protocols\All Applications
So I pretty much ran out of options, I would be really grateful for a fix.
