Exchange Import – Additional Permissions (4294075)

Note: This section is for ingesting data into Exchange 2010 SP 2 or later.
The Archive Shuttle Exchange Import module ingests data in to Exchange mailboxes or Personal Archives using MAPI. However, certain messages may fail to ingest using this mechanism even after a number of retries. By default the module will fall back to use Exchange Web Services (EWS) when this situation arises.
In order to support this failback, the service account that is being used to ingest the data must be granted an additional role within Exchange.
An example of the PowerShell command that can be used to grant this extra permission is shown below:
[PS] C:\>New-ManagementRoleAssignment -Name:VaultAdminImpersonization -Role:ApplicationImpersonation -User: ADomain\TheUser
