I have one user that when he opens up excel files most of the times they aren't visible. (On occation they are visible.)

When we try to preview the documents in the printing dialog to are shown correctly.
The documents are located on the network, a Small business server 2008.

When we log on to the same computer (Win7 Prof) as another user it works fine. (We have reinstalled the computer)
It also works when the "problem" user is log on to another computer and opens the documents.

Are there some kind of security setting on user level in office 2010?

Hi de0021,

Could you tell me whats the meaning of the excel file is not visible? If it was opened as shown in the following figure without spreadsheet? Or it is a normal spreadsheet just without contents in the cells. And did you get any pop up message bar from file when you open it?

You said the same file with other users account worked fine.  I suggest to check if the permission of the users account on the network is different from other normal users accounts. If yes, try to modify this users permission and try again.

Or this issue might be caused by DDE in excel. If you use Excel 2010 you might get an error when opening Excel or double clicking an Excel file that says There Was a Problem Sending the Command to the Program. Check if the user checked the checkbox Ignore other applications that use Dynamic Data Exchange (DDE), as shown in the following figure.

If possible could you take a screenshot and upload it so that we can get more accurate solutions to this problem. I am glad to help and forward to your reply.

Hope its helpful.

Regards,
