\n\tHi, so we've got a strange intermittent issue with some of our users where they cannot save an excel file on the network. We have 3 Windows 2008R2 file servers, replicating using peerlink, and people are accessing them through a DFS namespace. \n\t. \n\tWhen this issue occurs, which is not all the time, the user can literally create a brand new file on the network and try to save it, and he immediately gets the error noted above. What I'm saying here is that we know for a fact no one else is in these files and have eliminated that as a possible cause.
If the AutoRecover and AutoSave option is turned on in Word 2013, Excel 2013, and PowerPoint 2013, then you can automatically save versions of your file while you're working on it to avoid losing your work if a crash, power loss, or you close a file without saving happens.
