Outlook IMAP in PHP
I'm trying to retrieve inbox mail using IMAP, but I'm encountering the following error. I've attached the code and error details below. Please advise. $imapServer = "{outlook.office365.com:993/imap/ssl/novalidate-cert}INBOX"; $username = '*************'; $password = '*************'; // Use an App Password for security $imapStream = imap_open($imapServer, $username, $password, OP_READONLY, 0, ['DISABLE_AUTHENTICATOR' => 'GSSAPI']); I'm getting this error: A PHP Error was encountered Severity: Warning Message: imap_open(): Couldn't open stream {outlook.office365.com:993/imap/ssl/novalidate-cert}INBOX Filename: controllers/Cron_Controller.php Line Number: 39 Backtrace: File: C:\xampp73\htdocs\WPS2.0_2025_03_04_1847\application\controllers\Cron_Controller.php Line: 39 Function: imap_open File: C:\xampp73\htdocs\WPS2.0_2025_03_04_1847\index.php Line: 348 Function: require_once A PHP Error was encountered Severity: Notice Message: Unknown: LOGIN failed.
