Users still able to access any mailbox irrespective of permissions. What to check?!
Posted on 2006-05-30
Alriiighty, basically one of the sites I manage as 50+ users, among other servers we have a DC and an exchange server, we had an issue 6 months ago with the Information Store which resulted in me exmerging the mailboxes out, creating anew store and merging them back in. Since then however, all users have been able to access any other mailbox, calendar etc and not only view but also change and delete emails, appointments etc. Even though some mailboxes have editor permissions for certain staff to read appointments etc, anyone can add, edit and delete anything from everyone one elses outlook. As you can guess this is a serious security issue, one that I have been unable to sholve in the short time that I have attempted to fix this. Before resorting to microsoft paid support I thought I'd pick someone's brain on here. I can obtain more specific information if it will help in narowing down the problem.
