Microsoft Office hosted files remain locked until the server is restarted
McAfee VirusScan Enterprise 8.0, Patch 15 + HotFix 311933 McAfee VirusScan Enterprise 8.0, Patch 16 Microsoft Office Suite Microsoft Windows (all supported versions, see 613414)
Microsoft Office temporary files are not deleted. When using Microsoft Excel or Microsoft Word, it is not possible to save, rename or delete files. Microsoft Office files are being locked. Locked files are only released after a computer restart. The Microsoft Office application displays the following error:
Microsoft Excel Save not completed. File rename failed, Retry?
Clicking Cancel generates the following message:
Microsoft Excel Your changes could not be saved to 'Tape logs v1.5.xls', but were saved to a temporary document named <File_Name>. Close the existing document, then open the temporary document and save it under a new name.
Change or Cause
The file system filter driver in this release, in conjunction with the opportunistic locking mechanism (enabled in Microsoft Windows operating systems by default), can cause server-hosted files to remain locked until the server is restarted.

Sorry about dragging this back up. I'm having a similar issue on my network. Server 2003 R2, ePO 4.0.0, VS 8.7.0i. The only time I see the issue though is when I use the 'Convert' function in MS Excel 2007 on any of my client PCs to convert an older xls file to the current file type .xlsx When I do so McAfee on the file server will lock the temp file ~$filename.xlsx until I stop the service McShield on that server. As soon as I stop McShield all of the locked files go away.
So, a wild guess is that since I am on more recent versions of ePO and VS, the only solution I have from the options you listed is to disable OpLocks maybe?
