missing/lost files in office 2007 (64bit) after saving

We have deployed Office 2007 on a SBS 2008 network (64bit) after some
problems converting the ACT data base & associated Excel & Word 2003 document
formats everything seemed to getting along. Yesterday I had a call to say an
Excel spread sheet, converted on the 9th March, had disappeared after a
recent save. The shared spread sheet (located @ \\server1\actshare\documents)
has been used for several days & it appears in the “recently opened†list at
the top of the workbook but when they try to open it they receive a file path
error & when I search the server the file is nowhere to be found. Can anyone
help me with this please?

 

This isn't a 64-bit issue, and could happen at any point with an office
document saved to a network UNC point. There are any number of possible
causes, including user error as the single most likely cause. But it's also
possible, especially if working on the file from a wirelessly connected
workstation, to have an interruption in network connectivity cause the loss.

The recovery can be accomplished either by restoring a backup or, in some
cases, by finding the temporary file that Office creates while you're
working on the document and renaming it.

 

My customer site is seeing this also. local user folder is stored on server, recent file list shows all the documents they have edited, but they no longer exist as of the 17th.
Server 2008 R2, seems to only affect office file types and pdf's.

 

try office ng or server
