I want to use my Macbook Air 2011 as an external disk for my iMac 2011. I connected the two with a Thunderbolt cable and when starting the MacBook Air I pressed "T" and it worked except with Office documents. Can anybody help?

Question

I want to use my MacBook Air as an external disk to my iMac. I talked to Apple care and we solved it by connecting a Thunderbolt cable between the two computers. I then turn on the MacBook Air while pressing the "T" and it works. I can sit and work on my iMac and grab/change/save the files that are in my MacBook Air EXCEPT for the Microsoft Office files. I called Microsoft and they can't solve it. They say it might be a problem with the Thunderbolt cable. Has anybody have this problem?
Both computers are 2011 and they both have Office 2011.
Thanks in advance,
Alejandra

For Word it says "Word cannot open this document. The document might be in use, the document might not be a valid Word document, or the file name might contain invalid characters (for example, /)"
For Excel it says "the file could not be found. Check te spelling of the filename, and verify that the file location is correct. If you are trying to open the file from your list of most recently used files on the File menu, make sure hat the file has not been renamed, moved or deleted.
I tried this with many different documents, and I always get the same message.
