You can specify Access Control List for your Mailboxes to grant access to those Mailboxes to other CommuniGate Pro users.
Select a Mailbox in the Outlook Folder List, and use the Properties menu item to open the Properties dialog box. Open the Permissions panel:
Use the Add and remove buttons to specify the Accounts and other identifiers to specify those who should have access to this Mailbox.
Select an identifier in the list and use the checkboxes to grant required access rights to this identifier. See the Mailboxes section for more details on Mailbox ACLs.
Note: a user needs to have the Admin Access Right in order to specify the default Mailbox (Folder) View.
