At work we are currently checking to create a generic mailbox for every store of the company, like a branch mailbox. However, each store has multiple users (POS users and managers) and we need to give everyone the access, even the users who don't have a mailbox on their own.
For example, the store in Kingston has 3 managers (real persons) and 5 POS users (branch.kg01 - branch.kg05). We want to create a email kingston@ourcompany.com that each one of them will be able to access via Outlook.
I tried creating a mailbox for one the POS users, then give the others a delegate access but since the other POS users don't have an existing mailbox, we can't give them access.
Is there a way in Exchange we can create a sort of Shared Mailbox without using delegates?
EDIT: I tried using a Shared Mailbox, but it still needs a base mailbox to be added to. The managers have their own email, but not the POS users.
