Error: The Autodiscover service returned an error

Article ID: 71
Last updated: 15 Feb, 2014

[Error] Error connecting to the mailbox. There is a configuration, password or autodiscover service availability problem. Additional details follow: The Autodiscover service returned an error.

More information:

Typically when this error is generated it is because the single sign on (SSO) application isn't able to issue the account a token.  Is there an SSO solution in place?

Suggested Resolutions:

  • Try installing the Office 365 Sensor with an account that is not dependent upon SSO.
  • Or, to bypass SSO and Autodiscover functionality set the UPN value to be the email address.  When this is done there isn’t a reliance on SSO or Autodiscover to resolve the account.
