I'm running Windows 8.1 with Office 365, all 64bit. This happens with Word and Excel both. I can save documents locally, OneDrive, OneDrive for Business but not my company's file server. This happens when I'm remote and local (in the office). I have uninstalled and re installed Office 365 several times. I have removed indexing on the file server folder than I am trying to save to.
I have removed file indexing on the folder containing the documents...same results
I am the only one editing these docs...
I have uninstalled 64 bit...reinstalled 32bit Office...same results
I returned the system to 64bit office...
I'm running McAfee Enterprise + AntiSpyware Enterprise 8.8 and have no way of disabling it
