I've run into a weird issue that is stumping me. I have a user that needs to be able to write to an excel file on one of our shares. Another user, who has the exact same level of access (as verified by the Effective Permissions utility in Advanced Security) can write and save to the excel file, but when this user tries to do so it returns "Access Denied." I've verified that his user is a member of the group, I've verified that his login is being viewed as a member of the group, I've verified that there are no Deny permissions set. I've also verified that neither user is an Owner of the file. Has anyone run into this kind of issue before? It's confusing me because everything I'm seeing shows that he should have permission to save the file, but he can't, meanwhile another user that is a member of the exact same groups *can*.
