After installing Windows 10 and Office on a new laptop, I started getting the following error message when I tried to click on any link in any email message or click on a table of contents link in a Word doc:
"Your organization's policies are preventing us from completing this action for you. For more info, please contact your help desk"
While it's not an entirely bad thing to have email links require a copy and paste, it's a real problem with other links like the Table of Contents in a long Word document.
There is a KB article at https://support.microsoft.com/en-us/kb/310049 that discusses this issue. The solution for Windows 10 is to find a system that doesn't have the problem and export a registry key then import it into the offending system. The key it references was missing from my system.
The steps that worked for me were to find a Windows 10 system that didn't have the problem, run regedit and locate the following subkey:
Then you export the subkey to a file, copy the file to the system having the problem and import it into that system's registry (either by double clicking the .reg file or importing it via regedit).
There is a last verification step to verify the String (Default) value of "HKEY_CLASSES_ROOT \.html" key is "htmlfile".
