Cannot save Outlook account settings

---

Problem:

Cannot save Outlook account settings

Setup: Windows 10
Outlook 2013, 2016
ZCO v8.6
AD or Possibly Samba PDC

When configuring ZCO/Outlook account information you may see the following errors:

Errors:

"You can not save any changes. The path to store the files ZDB not specified or is not accessible. If you have selected the storage of ZDB files in a folder outside, be sure to specify the correct path to that folder."
OR 
"You can not save any changes. impossible to complete the action."

Solution:

Sometimes Outlook has problems, when configured through AD or Samba domains, saving locally. In order to allow saving local settings, please try the following registry edit:

Create or set a new registry DWORD value, named ProtectionPolicy, value 1, to enable local backup of the MasterKey instead of requiring a RWDC in the following registry subkey:

HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb" 

Once you update that registry key, try re-configuring your Zimbra profile
