Few days ago I came across a very annoying issue with a new SharePoint server and a Word document.
I uploaded a regular Word document to my SharePoint 2013 server easily.
But when I try to open Word file an error message occurs, and the file couldn’t be opened properly.
Word experienced an error trying to open the file.
Try these suggestions.
* Check the file permissions for the document or drive.
* Make sure there is sufficient free memory and disk space.
* Open the file with the Text Recovery converter.
There cause is actually Word’s default security settings… probably a good thing!
You can resolve this issue in at least two ways:
1. Disable “Protected View” From Settings (not recommended)
You can disable protected view for files originating from the Internet.
This option isn’t recommended, as it potentially exposes you to unnecessary risks by unchecking the highlighted box below in the Trust Center (Word Options > Trust Center > Trust Center Settings > Protected View).
Anyway it does let you access the file(s) again.
2. Add SharePoint site to Trusted or Intranet Zone (Recommended)
This is the preferred option, as it means you are trusting one site rather than the whole of the internet.
From Internet Explorer settings or from your Control Panel > Internet Options, add the site to either the “Trusted” or “Local intranet” Zone:
The bad news are you have to configure this option in each Office application separately.
