CloudLink tasks for Exchange include an optional action to synchronize mailbox delegation permissions. This option enables users to read in Personal.cloud the archived messages of Exchange mailboxes for which they have Full Access delegation permission.
Note the following regarding mailbox delegation synchronization at this release:
CloudLink synchronizes the delegation permissions that have been applied to on-premises Exchange user mailboxes and shared mailboxes. The Exchange administrator typically applies these mailbox delegation permissions through the Exchange Admin Center or the Exchange Management Console, or with PowerShell.
CloudLink does not synchronize delegate access to mailbox folders that users can set from Outlook.
CloudLink synchronizes delegation permissions that have been granted to users and mail-enabled security groups.
