Issue
In some situations, the Office 365 module might reports the following when ingesting data into Office 365:
2016-03-11 14:37:33Z|1299| 34|ERROR| ProcessFailedResult| Error while ingesting Item with Id [a106a19a-5099-1f65-204b-6b8f71e2c371] ItemRoutingId: [11345] Error: [Microsoft.Exchange.WebServices.Data.ServiceRequestException: The request failed.

Solution
This may be caused by one of the accounts that have Application Impersonation rights being locked-out. Check and correct that in Office 365, and then see if the errors stop being logged.
