When you open templates or files using a hyperlink button or from Outlook's Shortcut navigation pane, you'll receive an unsafe hyperlink warning. You can disable the warning by editing the registry.
You may also receive the file open or save dialog when using a hyperlink button or shortcut. To disable this dialog when the "Always ask" field is grayed out, run Outlook as administrator. The "always ask" checkbox should be clickable. If not, you'll need to edit the registry for each file type. See Disable "Always ask before opening" dialog for more information.
The solution
Add a registry value to disable the warning dialog.
Open the registry editor and browse to the following registry subkey for
Outlook 2016:
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Security
Outlook 2013:
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Security
Outlook 2010:
HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Common\Security
Outlook 2007:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\Security
Note: If the Security key does not exist in your registry, you'll need to create it too.
Right click on Security key and choose New, DWORD.
Type (or paste) DisableHyperlinkWarning as the Value name then double click on it.
Enter 1 as the Value data to disable the warning. Delete the key or use a value of 0 to enable the warning.
Administrators will add the DisableHyperlinkWarning DWORD to the Policies key instead:
Outlook 2016:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Common\Security
DWORD: DisableHyperlinkWarning
Value: 1 (disable the warning), 0 (enable the warning)
Outlook 2013:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\15.0\Common\Security
DWORD: DisableHyperlinkWarning
Value: 1 (disable the warning), 0 (enable the warning)
Outlook 2010:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Common\Security
Outlook 2007:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Common\Security

Not working on Windows 10 with Office 2016 (Office 365)
did you use the 'do it for me' for outlook 2016?
Hi Diane. I have Office 2016 and Windows 10. I used your "Do it for me" file and it I keep getting a warning for this "C:\Users\Skip\AppData\Roaming\Microsoft\Templates\Skips Outlook Templates". The registry file has been changed because I checked it. Will you please help me?
Add the template folder as a trusted location in file, options, trust center.
What about Office 2016? I added the key under
HKEY_CURRENT_USERSoftwarePoliciesMicrosoftOffice16.0CommonSecurity but still get the pop-up warning when hyperlinking to a PDF stored on my local drive.....
Thx!
I'll check it - it should work. Did you restart Outlook? When using policy keys, you need to restart outlook.
It's working here - i'll update it with a ready-to-use reg file.
Thanks so much for this post!
I have been annoyed by these warning for over two years.
What about outlook 2013?
It's the same, but version is 15. I updated the "do it for me" and the registry keys for Outlook 2013. Thanks for bringing it to my attention that it needed updated.
