It is not safe to store any files in AFS which are databases that
are accessed via multiple applications at the same time.  This is
because there is no byte range locking supported in AFS.

The problem that was solved in AFS with regards to Office applications
is that the overlapped I/O problems which used to prevent Office
applications such as Word and Excel from even writing their files
into AFS have been fixed.

I am not aware of any problems being reported with file corruption
other than those related to byte ranging locking issues.
