I found out a way to open the files, but unfortunately not directly from the Outlook.
Here are the steps that i performed to open word and excel files:
- Right click on the file name
- Click Properties
- In the tab General look at the very bottom, below the Attributes it displays:
Security: This file came from another computer and might be blocked to help protect this computer.
Next to the text there is a button Unblock
- Click Unblock, then Apply, and OK
- Open the file regularly.
I'm still searching that rather lengthy and (so far) ineffective comment string on opening older versions of Excel using 2013. Like many here, I too an unable to open older versions - be they 2007 or 2003 - and my difficulty has nothing to do with Outlook.
It is NOT a program association problem and everything I have tried up to the point in the commentary has failed to solve the problem. Note that when I follow the above steps associated with a problem file there is no security message below the Attributes
area in the General tab and hence to Unblock option.
Note that I am using the desktop installation which came from Office365 and Windows 7. I do NOT get an error message - Excel opens but does not open a file (i.e., Workbook).
I'll keep trudging through the commentary to see if eventually one of the proposed solutions bears fruit.
