The issue: when saving a document from either Word, Excel or PowerPoint 2010, every so often it will show the message 'file' is currently in use. Try again later.

We started our rollout of Windows 7 beginning of this year, and this issue was infrequent, but is now affecting enough people to be a problem.

Usually, if you clear the alert, then save again, it works fine, though only in Word or Excel. Annoyingly, PowerPoint has a bad habit of changing the file to read-only after the error. So the only choice is to save to a new file name.

The issue seems to only happen to files in the user's My Documents, which is a redirection folder from their HomeShare.

The HomeShares are spread across 3 different file servers, 2 Windows 2003 and 1 Windows 2008 R2.

Has anyone seen this issue and know how to fix it?
