The ‘Resource not found: Resource could not be discovered’ error relates to Microsoft and often occurs with the Outlook mailer. It typically indicates that the email address you’re using for the authorization process doesn’t have an active mailbox associated with it.
When setting up an SMTP plugin like Easy WP SMTP with the Outlook mailer, it’s crucial to check the status of your mailbox. It should not be inactive, deleted, or hosted on-premise.
Resolving the Error – Solution
To fix the ‘Resource not found: Resource could not be discovered’ error, you need to verify that the email address you’ve provided in the SMTP plugin settings corresponds to an active mailbox. Make sure your mailbox is not inactive, deleted, or hosted on-premise.
Addressing these potential issues by either reactivating the mailbox, retrieving the deleted one, or moving your on-premise mailbox to the cloud, should resolve the error. However, if your mailbox is functioning correctly and the error persists, consider reaching out to Microsoft support, as the error originates from their end.
