The section for managing roles and permissions. There are two types of permissions in the service: account permissions and mailbox permissions, which are separately combined into the corresponding roles. Separate tabs are provided for the account and mailbox roles: Account and Mailbox.
Each tab has a search bar by role name, as well as a filter by permissions. In the lower right corner, there is the functionality to switch between pages, to the specified log page, select the number of users on the log page, the number of items in the log, and paging.
At the account and mailbox level, there are already system roles (not available for deletion) called Account Owner and Mailbox Owner, respectively, which include all permissions at their level.
