This is a new one for me, and I believe it may have popped up after the recent Windows Update:
“Word experienced an error trying to open the file”.
Now if I SAVE that same file out of outlook (or copy and paste it to a drive), and then open from there – it opens fine.
Here is the solution:
- Open Word 2010, 2013 or 2016
- Go to File | Options | Trust Center | Trust Center Settings | Protected View
- Un-check the “Enable Protected View for Outlook Attachments” checkbox
Click ok/save that setting.
Go back to outlook and your word document should now open fine.
I have double checked this and it does work fine for Word 2016 as well.
