Our user is unable to edit Excel documents within SharePoint 2007. We use Office 2010 32-bit. There are no error messages. It just does not save. During troubleshooting, noticed 3 SharePoint Add-Ons missing from IE9: Export Database Launcher, OpenDocuments
Class, and Stssync Handler. The suggestions were to 1) repair Office 2010, and 2) Uninstall and reinstall Office 2010. Neither option worked.
Noticed today while troubleshooting that Excel files do not modify at edit, but Word documents do. Checked permissions for the user within the library and she has contributor access. All other users in that user group are able to edit Excel documents. I
even deleted and reentered her within the permissions group, but the problem remains.
" Finally i figured out the cause to this problem. After having the load balancer data packet we took last week analyzed by the manufacturer and checking the http connections(using FIDDLER) being thrown by client machine to the load balancer, we found
out that the problem is caused by the following:
1) Insufficient setting in the Load Balancer
2) Change in http method handling between Office 2003 & Office 2010
Unlike Office 2003, office 2010 seems to be throwing LOCK/UNLOCK method towards the server regularly which is unfortunately NOT SUPPORTED BY DEFAULT on our load balancer(OS:Alteon 188.8.131.52). This blog helped me alot:
