We have a bunch of excel files that are at random becoming corrupt. The error message is excel has found unreadable content...
I believe this question is relevant to serverfault because the problem has only started occurring since we have setup folder redirection, roaming user profiles and offline files on our desktops. The files have been in use for around 5 years prior with no issues.
The excel files are located in a subfolder of our company folder on the server. The entire company folder is shared and available offline. About 32gb in total.
After one of the files became corrupt I tried to restore if from a backup. From one of the desktops I deleted the corrupted file on the server, I copied the new file to the existing location then opened, saved, closed, opened and noticed it was corrupted. I can recreate this occurrence many times, but the weird thing is it seems to be related to that particular folder. If I copy the file to any other folder (even other shared and available offline folders), open, save, close, reopen it then it is not corrupted. It only gets corrupt if I copy it to its original location.
Does anyone know what an earth is going on?
Using windows 7 on all desktops and windows server 2008 r2 on the server.
