--- Comment #2 from C. Leu kle@bluewin.ch --- Yes, I can confirm that this really solved the problem. I had just to create a "Recent" folder in the corresponding user profile.
And it looks that this issue does NOT occur on user profiles which already includes a "Recent" folder.
Whatever, many thanks for the fast help and resolution Austin English!
So this problem is now "bisected" and understood. It is just necessary to establish regarding older Office versions like 2010 a "Recent" folder in the user profile. That's all. Maybe this is not needed for newer MS Office versions but it is definitely for older ones. ;-)
