E-sign contracts and sharing cases

Hello,
I would like to ask you if there is any possibility to set a team for Adobe Acrobat Sign. In team we have 3 people with accounts on their personal corporate mail addresses registered and all of them send calculations to customers for signing. Of course, via their mails, so they receive approved contracts in their mailbox and only them, separately, can check status of their agreements. Because of sickleave, vacations and other absences, we need to find a solution how to share these cases at one place and work on them, be able to see their current status and if necessary, complete it. 
Is there any solution except new account registered to shared mailbox with sharing credentials? 

thank you!
