Operating:

- Windows 7

- Office 2010

When opening an excel file from my NAS drive, I get the message "this file originated from an internet location and might be unsafe" with the option to click on "enable editing"

What I have done so far:

- Enabled "allow trusted locations on my network"

- Added the location of the NAS drive. (example:   \\XX-222X22\)

-- Enabled "subfolders of this location also trusted"

But the problem remains. 

When unboxing "enable protected view for files from the internet" the problem is resolved.

But off course I want actual files from the internet to be intercepted. So unchecking this box is not really an option.

- The issue occurs with all excel files from the network hard drive (NAS drive)

- It has the problem with all excel files. (.xlsx and .xls)

- I have another computer on the network, running on windows vista, and the same version of excel.

This computer does not have any problems with any of the excel files.

And I never had to assign a trusted drive, or un-check the "enable protected view for files from the internet"

The question is why the external hard-drive (NAS) is treated as an internet connection.

And how to fix this.

All help is much appreciated.

Thanks.

Hi,

Have you tried to add the NAS drive path in Local intranet through IE, see if it solve your problem, thank you.

Did the above solution work for you?
