When performing a Microsoft Office 365 import in Okta, the process fails if the API connection uses invalid Global Administrator credentials. Re-authenticating the integration with valid credentials in the Okta Admin Console resolves this issue. Administrators encounter the following error during the import process:

An error occurred during import Could not validate your Office 365 credentials, received error: 400 AADSTS50126: Error validating credentials due to invalid username or password Trace ID: Correlation ID: Timestamp:

• Okta Identity Engine (OIE)

The Microsoft Office 365 import fails because the Global Administrator credentials used to establish the API connection are invalid.
