For some reason, IMAP using office365 is not working

Here error log:

2023/04/27 21:27:16 [error] 77464#77464: *6 FastCGI sent in stderr: "PHP message: PHP Warning: imap_open(): Couldn't open stream {outlook.office365.com:993/imap/readonly/ssl}INBOX in /var/www/html/post.php on line 623" while reading response header from upstream, client: ip, server: domain.tld, request: "POST /post.php HTTP/1.1", upstream: "fastcgi://unix:/run/php/php8.1-fpm.sock:", host: "domain.tld", referrer: "domain.tld/settings_mail.php"

tried below based on the error

telent outllok.office365.com 993 - works fine
checked the imap extension - enabled
firewall disabled
using app password or account password - same error - credential works on other appss
changed the imap config to: $imap = imap_open("{{$imap_mailbox}}INBOX", $config_smtp_username, $config_smtp_password, OP_READONLY, 0, ['AUTHENTICATOR' => 'LOGIN']);

and

// Connect with LOGIN authentication method

$imap = imap_open("{{$imap_mailbox}}INBOX", $config_smtp_username, $config_smtp_password, OP_READONLY, 0, ['DISABLE_AUTHENTICATOR' => 'PLAIN']);

- people on google reporting same thing with php imap, so i`m about to try bellow acording to my ChatGPT friend recommendation:

// Validate admin role

validateAdminRole();

// Prepare connection string with encryption (TLS/SSL/<blank>)

$imap_mailbox = "$config_imap_host:$config_imap_port/imap/readonly/$config_imap_encryption";

// Connect to IMAP server

$imap = imap_open("{{$imap_mailbox}}INBOX", $config_imap_username, $config_imap_password);

// Check for errors

if (!$imap) {

die('Could not connect to IMAP server: ' . imap_last_error());

}

// Search for new messages

$message_numbers = imap_search($imap, 'UNSEEN');

// Loop through each message

foreach ($message_numbers as $message_number) {

// Fetch the message headers and body

$headers = imap_headerinfo($imap, $message_number);

$body = imap_body($imap, $message_number);

// Parse the message into a ticket object

$ticket = parseMessageIntoTicket($headers, $body);

// Add the ticket to IT Flow

$result = addTicketToITFlow($ticket);

// Mark the message as read

imap_setflag_full($imap, $message_number, "\\Seen");

}

// Close the connection to the IMAP server

imap_close($imap);

It uses the Microsoft Graph API to access the user's mailbox and retrieve the emails. The retrieved emails can then be parsed and processed to create tickets in ITflow.
