We have a remote office which has a 2mb WAN link, The users in the remote office have a variety of Office installs from 2003 to 2010 SP1.
When attempting to open an excel file over the WAN link (The file is on our main shared drive in Sydney) they can open and edit the document however when it comes to saving they receive "Document not saved" and the original document is gone and a .tmp file remains where the original file was on the network drive/shared folder.
If they then hit save a second time it saves correctly and the document is in the correct .xls format.
The excel files do have some funky tables etc in them and are a few mb's in size, however we have the same issue with a new excel document with only one word written in it.
Does anyone know what would be causing this issue?
We have tried added NetworkResiliency and PivotTableNetworkResiliency as per http://support.microsoft.com/kb/291204.
We have tried removing certain hot fixes from Microsoft as mentioned in http://support.microsoft.com/kb/983458.
We added the share to be a trusted site.
There are no errors in Event Viewer.
I have found another few threads on similar issues with no fix:

We do have a RiverBed at the remote office and one at the site in Sydney which is for network optimization. On the RiverBed with have all CIFS ports added and QoS marking done so it should be optimized.
Any assistance with how to fix this annoying issue would be greatly appreciated.
Thanks
