Mailbox contains all the important emails, communication and documents that have been shared with the sites and these documents are helpful especially when it comes to reconcile TMF. People with specific positions only have access to mailbox for particular studies because in clinical industry mailboxes are used for sharing study related information. It can be hard to track all the documents from CRAs and study coordinator and this is where shared mailbox helps.
When the study is complete, this entire shared mailbox that includes all the emails and documents is given to the sponsor as a record of every discussion and information that was exchanged during the studies.
Study coordinator and specialist who have been involved in all the study are responsible to maintain the entire shared mailbox.
