Outlook 2007 on Exchange 2010- We have a number of shared mailboxes that multiple people work out of for workflow purposes. Most people have the ability to read full details, delete all items, create items, create subfolders, and edit all. To process an email in the shared mailbox, the user will move an email from the inbox to a work in progress folder (still in the shared mailbox). Once the task is completed, the user moves the email to a completed folder (again, still in the shared mailbox). Note that we were told in order for people to move emails to folders in the shared mailboxes, they had to have delete all authority. Lately we have been having a few incidents where a person will accidentally move an email from one of the shared mailboxes to their own mailbox. The email effectively disappears from the shared mailbox and we can't trace it anywhere. Recently, we have "misplaced" a critical email. We are seeking suggestions on how to allow people to move emails within the shared mailbox, but prevent them from moving emails to outside of the shared mailbox. We would hate to lock down moving period because the inbox would become confusing and extra burden would be placed on one person to be the only one to move emails. Thoughts, comments, suggestions would be appreciated. Thanks in advance.
