we had a similar problem, when we upgraded to 5.3.4R3P2 we no longer had any issues. you might want to upgrade to the latest version if you haven't already.

Subject: Problems with MS Excel and Oplocks?

I've seen a strange problem over the past few days. We have MS Windows 9x/NT users running Excel 97 and Excel 2000. Dozens of minutes, or even hours, after a person stops editing the file (Save & Quit), you can't access the file via NFS or CIFS. CIFS apps complain the file is in use. NFS clients complain with "permission denied". Doing a truss of a chmod or rm on the file shows ERR#13 - EACCES. The only way to "unlock" the file is t have the CIFS user logoff of the client, or to terminate the CIFS session of the Filer. The user clearly does not have any apps open on the CIFS client.

This sounds suspiciously like Windows 9x/NT and Excel is doing something weird to keep the lock open. Has anyone seen this with Excel, and how did they resolve it?
