Mailbox permissions are granted through roles, just like account permissions. The key difference is that you must select the mailbox that the role applies to.
If the account has many mailboxes, the Mailbox tab shows only the 3 most recently created mailboxes. Use search and filters to find the required mailbox instead of scrolling through the full list.

Use the search field to find a mailbox by name. Use the permission status filter next to the search field to switch between these mailbox groups:
All — shows all mailboxes available for permission management.
Mailboxes with permissions — shows mailboxes where the user has at least one permission.
Mailboxes without permissions — shows mailboxes where the user has no permissions.
Open the user page in the Admin panel.
Go to the Mailbox tab.
Select the mailbox you want to grant access to.
Create a role for the selected mailbox and choose the required permissions.
Click Invite in the page header.
After you click Invite, the system shows a notification in the upper-right corner and sends an invitation email to the user. The next steps depend on whether the user is new or already exists.
To review the full list of permissions, see Mailbox Permissions.
