I have one particular user who has just about every possible problem with Excel. Intermittently, she can't copy Excel files from one network location to another; Excel crashes regularly; Excel opens files in protected mode; she can't recover files; (Autosaved) files all over the place because of the crashes; copying files from one network location to another occasionally causes the new file to be corrupted, and on, and on.
She's using Office 2013, and any network files are on Windows Server 2012.
We have tried everything we can think of at this point. She's on her second Windows profile, second PC, she has 8 GB of RAM (some Excel files use 1.5 GB of RAM, though most are pretty normal); an i5 chip, Win7 Pro. We've changed her Ethernet cables and the switch she's plugged into, and a dozen other things to see if anything would make any difference.
It's all her, no one else has anything approaching this level of problems, though she does more work on large, networked Excel files than anyone else.
Does any of this ring a bell for anyone, and did you find a solution?
