I have a user with read permission for library with excel files. When user clicks on document it opens in readonly mode, but user has option to edit file and if he does that all changes are saved on server. I think it's strange - read permission should not allow to modify document, but it dose. Any idea how to solve this issue?

[EDIT] So lets sum up: 1) excel file is document library with unique permissions, only I and enother user can access it, all other groups and users excluded; 2) excel file inherits permissions from document library; 3) that user has read permission and all over the site he never gains write permissions directly or trough group; 4) When i with write rights open the file i get pop-up window it asks me I want to read file or edit it, if user opens it - he gets message that this file can be harmfull; 5) Excel file is opened Excel 2010 and states that file is opened in readonly mode from server, but you can click edit workbook and save - saves are made on server; 6) I checked that user can modify any excel file in directory.

I would double-check that the user was not inadvertently included in some other group with write permissions. While the user may still be allowed to save it locally (unless you are using Information Rights Management server), he or she should not be allowed to save the doc back to a document library with just read permission.

  • This folder has unique permissions so i don't think that the issue Nov 10, 2010 at 16:49
  • I don't suppose the user in question would be a site collection administrator by chance? That would override it...

  • Let me say again - its just a simple user, his not admin. Folder with documents has unique permissions and his permissions are set to read Nov 11, 2010 at 7:42
  • I don't see where you said before that it was not an admin user. User can mean a lot of things. Forgive me if I missed it. Well, somewhere up or down the chain this user is being given write permissions. When you say "folder" do you actually mean a folder in a document library (my assumption), or is the document simply in a document library? Also, does this occur for all documents in the folder or just the one? I wonder if write permission was granted at the document level itself? It would also override the folder permission.
