We are having a strange issue with Microsoft Excel and saving to a network share. When anyone (users or admins) saves changes to an Excel workbook saved in a particular network share it generates a .tmp file. From my research this is to be expected, but the temp files should clear when the workbook or Excel is closed.
These files are building up and so far the only way to get rid of them has been to manually delete them.
From my research on this issue a lot of articles have been opened with similar problems, but none of the solutions seemed to have fixed the problem. I have found that if I grant Full Control permissions to 'Everyone' on this folder the tmp files do not appear, but I can only do this for testing purposes. I have tested opening and saving an Excel document with a domain admin account (which also has Full Control access to the folder) and the tmp files still generate unless the 'Everyone' group has Full Control permissions.
Does anyone have any suggestions on how to resolve this? The issue occurs regardless of what Operating system the client is using or version of office. I have tested this with Windows 7 and Windows 8, along with Office 2010 and 2013.
