Troubleshooting Microsoft Office 365 Errors

This topic provides details for troubleshooting known errors that result in inaccessible items (mime-type:"filesystem/inaccessible“) that may be encountered when processing data.

ERROR

com.nuix.data.util.RetryCallable - Final retry attempt number 10 failed

• Description: The request to retrieve data from Office 365 has failed. This error is likely to occur after a connection has been throttled and the maximum number of retries has been reached.
• Impact: Data will be missing from the evidence set.
• Resolution: Retry the ingestion once the connection is no longer being throttled.
• Important: To reduce the potential for data loss resulting from connection throttling, it is recommended to not use more than four workers when ingesting data from Office 365.

To try and prevent future failures of this type, the following system properties can also be configured at startup:

• Increase the default (10) maximum retry count:
  nuix.data.msgraph.retries=10
• Increase the default (1 second) retry delay:
  nuix.data.msgraph.retryDelay=1
• Increase the default (5 seconds) retry delay increment:
  nuix.data.msgraph.retryDelayIncrement=5

• Description: Indicates that an error with code “ErrorAccessDenied” was returned from the Microsoft Graph API for this request.

  nuix.data.msgraph.http.use-system-props=true

  See HttpClientConfiguration for details on configuring the Apache HTTPClient.
