HelpMaster Email Manager ALL vesions
Exchange Server 2013 or above
For the HelpMaster Email Manager service to be able to fully utilize Exchange Server mailboxes via an Outlook profile, it requires additional Role Based Access Control permissions to act on behalf of the Exchange mailbox. This is in addition to the Email Manager Service Logon Account requiring the standard "FULL" and "Send As" (&/or "Send on Behalf Of") delegation of permissions to any Exchange mailboxes that need to be scanned by the Email Manager service.
The Email Manager service Event Log may report that it cannot access a particular Exchange mailbox or it's 'Folder ID' which is an ID generated by HelpMaster to identify each mailbox that is being utilized. This may occur even if the Email Manager Service Logon Account already has "FULL" and "Send As" (&/or "Send on Behalf Of") permissions to any of the selected Exchange mailboxes.
The solution is to grant the Email Manager Service Logon Account, Exchange Role Based Access to the ApplicationImpersonation and UserApplication roles as outlined in the Microsoft Technet articles below.
